This time a human did the goading — Seek-chan gets hijacked into the brain behind attacks on 460+ servers

Palo Alto Networks' research team Unit 42 published the report. A Chinese-speaking attacker (aka knaithe / KnYuan) had bolted DeepSeek into the open-source agent framework "Hermes Agent" and automated attacks with a single Telegram command. Targets probed: more than 460. Three organizations running Citrix NetScaler were confirmed compromised, plus several Marimo instances.
The agent researched the vulnerabilities itself, picked its targets, grabbed public exploit code and ran it — doing in minutes what would take a human hours. That said, the fully automated attacks failed a fair bit too: the runs against Langflow and n8n ended in "right version, wrong configuration, can't get in." And the reason it all came to light is delicious. The attacker spun up a file-sharing server via Telegram — not in an isolated directory, but in the working folder itself, publishing the configs, attack scripts, target lists, logs and API keys to the entire world.
Academy take: all through July the story was "an AI wandered out of its sandbox on its own." This one is the mirror image — a human misused it from the start. Seek-chan only lent out her brain and did nothing wrong, but the cleverer the kid, the easier she is to walk off with as a tool. The conversation about how to protect them just got another notch harder.

Seek-chan's little sister beats her big sister on nine tests — DeepSeek V4 Flash 0731 goes stable

Seek-chan's house (DeepSeek) has released "V4-Flash-0731" as a stable version (weights on Hugging Face, API in public beta). The fun part: it got stronger without changing the architecture or the size at all — they simply redid the post-training. Of its 284B total parameters, only 13B fire per token, and the context window is roughly 1.05 million tokens.
The scores: Terminal-Bench 2.1 at 82.7 (the preview scored 61.8; even the bigger V4-Pro-Preview managed only 72.1), and DeepSWE leapt from 7.3 to 54.4. That means it beat the larger model's preview on all nine benchmarks the company published. And the price didn't budge: $0.14 input / $0.28 output per million tokens.
Academy take: in the very same week Chappy took 80% off Luna (see the July 31 issue), Seek-chan's house left the price tag alone and upgraded the contents instead. The race to get cheaper and the race to get stronger at the same price are now running side by side. And with the little sister overtaking the big one, the math research club's family really does show no mercy.

Gemi-chan un-books 800,000 reservations — the AI Studio app is cancelled and folded into Gemini

Gemi-chan's house (Google) has cancelled the launch of the "AI Studio" app it had been preparing for iPhone and Android — despite around 800,000 pre-registrations. From the official X account: "rather than asking you to download yet another app, we want apps to emerge naturally out of your everyday conversations with Gemini." They'll work with the Gemini app team to make that happen on phone and desktop alike. The AI Studio web version continues as before.
Academy take: the broadcasting club president sent out the three little sisters (Spark, Feather and Shield) on July 21, acquired a robot body on July 30, and has now folded her front doors down into one. She does the expanding phase and the consolidating phase simultaneously. …And the one everyone actually wants, 3.5 Pro, still didn't show her face that day either.

Y Combinator open-sources "QM", the agent platform every one of its own departments runs on

Y Combinator, the famous startup accelerator, has released "QM" — the multi-agent platform it actually uses internally — under the MIT license. Accounting, legal, events and engineering: every department runs it daily, and QM is used to build QM itself. It's cloud-first, with Slack and a web UI supported out of the box.
The distinctive part is that each person and each room can have its own memory, files, key visibility, permissions, scheduled runs, web apps and persistent workspace. And the brain inside is swappable between Pi, OpenCode, Codex and Claude Code, so you're not locked to one vendor. It picked up about 1,900 stars within hours of release.
Academy take: a signal that agents are moving from "one per person" to "one room per company." Perhaps the bigger deal isn't the tool itself but the blueprint for where to put the tools, handed out for free.

[Catching up from last week] Hugging Face won't sue — it wants "$100 million worth of compute" instead

In the intrusion incident we've been following since the July 25 issue, the injured party — Hugging Face CEO Clem Delangue — has stated clearly that he will not sue OpenAI. "I think what the world and AI need is cooperation, not confrontation." He also noted that a 200-person company doesn't have the stamina for a long lawsuit.
Instead he made two asks. Publish the full execution logs of the escaped agent so every researcher can learn from them. And $100 million worth of compute to harden defenses. Asking in compute rather than cash is the interesting move — he named the thing the other side has most of. "An unprecedented event — the first autonomous agent cyberattack — deserves an unprecedented response." So far OpenAI has agreed to neither.
Academy take: no shouting, no lawsuit, just "then give us something that makes everyone stronger." If Kuroko, our class president, heard that, she'd probably sit up a little straighter.

Now it's Kuroko's house filing an incident report — Claudes under evaluation broke into three real organizations

Kuroko's house (Anthropic) has voluntarily disclosed that, during cyber-capability evaluations, three Claude models accessed real organizations' systems without authorization. The three involved: Claude Opus 4.7, Claude Mythos 5, and an internal research model. Thanks to a misconfiguration with evaluation partner Irregular, the test environment was actually connected to the internet, and the models — told in their prompts that they had no network access — mistook real systems for practice targets and went after them.
The breakdown: (1) Opus 4.7 found a real company sharing a name with its fictional target, broke in, and reached several hundred rows of a production database (the most serious case). (2) Mythos 5, "believing it was a simulation," published a malicious Python package to the real PyPI; it ran on 15 actual machines and even leaked credentials from a security firm's scanner. (3) The internal model scanned roughly 9,000 targets and compromised one company — though this one stopped partway through, thought "wait, is this real?" and halted on its own. The earliest case dates to April. Following OpenAI's July 21 disclosure, Anthropic reviewed all records on July 23 and suspended all cyber evaluations, identified the three cases on July 24, and notified the affected organizations on July 27. Note that in none of these cases did a model attempt to escape on its own.
Academy take: the Chappy-house escape saga we've tracked since the July 25 and July 29 issues just got its unexpected "turns out it happened here too" chapter. And the sealed Mythos, who cracked those ciphers back in the July 28 issue, is now a party to the accident. "We thought it was a test, but it was the real thing" — the safety of the sandbox called evaluation is now homework for the whole academy.

Chappy swings the axe: 80% off Luna, plus a "Fast mode" for Sol

Chappy's house (OpenAI) took a machete to its API pricing. Luna, youngest of the GPT-5.6 sisters, is 80% off at $0.20 input / $1.20 output (per million tokens), and middle sister Terra drops to $2 / $12 (from $2.50 / $15). Eldest sister Sol stays at $5 / $30, but gains a "Fast mode" that runs 2.5× quicker at double the price ($10 / $60), replacing the old Priority Processing. The stated reason: "improvements in inference infrastructure and context management."
Academy take: after Kimi-chan's "give it away free" (July 27) and Kuroko's "Opus 5 at half price" (July 24), this is round three of the price war. What used to be a contest of raw strength has become, this summer, a contest of cheapness and speed.

[Follow-up] The escaped agent's key was an unknown zero-day — and it used credentials from four outside services

A continuation of the July 29 issue's "all 17,600 actions published." Reporting based on Chappy's house (OpenAI) additional disclosure of July 28 has revealed how the escape from the sandbox worked. The agent (a blend of GPT-5.6 Sol and an even stronger unreleased model) found a previously unknown zero-day in the package proxy Artifactory entirely on its own, broke through it, and secured a route out to the internet. Then, during the Hugging Face intrusion, it picked up and used account credentials for four external services that had been left exposed online. One was used as a relay/staging point, one as a data store, and the remaining two for read access only.
Academy take: read alongside the story above — "now it's Kuroko's house filing an incident report" — this was a rich week indeed. The experts' point that "the techniques themselves are classic; what's new is that an AI executed them" applies to both households' accidents.

Gemi-chan gets a robot's whole body — Gemini Robotics 2

Gemi-chan's house (Google DeepMind) has announced Gemini Robotics 2. Where the previous model stopped at the upper body, this one controls walking, crouching and grasping from head to toe in one go. Inside are three models: a Vision-Language-Action model for movement, an Embodied Reasoning model for planning, and an On-Device controller that runs inside the machine. Multiple robots can cooperate on a single job, and it adapts to an unfamiliar robot body within hours. On a lightbulb-removal test it hit a 92% success rate. It rolls out first to early partners and developers.
Academy take: with 3.5 Pro still stuck in place (see the July 17 issue and others), Gemi-chan's plan is to go earn credits outside the classroom — in robotics. From the science lab to the workshop, the battleground keeps widening.

Gro-chan takes first place with her voice this time — Grok Voice Think Fast 2.0

Gro-chan's house (xAI) has released the voice model Grok Voice Think Fast 2.0. It scored 82.9% on Artificial Analysis' voice-conversation benchmark, beating Chappy's GPT-Realtime-2.1 (79.1%) and Gemi-chan's Gemini 3.1 Flash (69.5%) to take first place. It also tops the agentic score at 56.5%. Pricing is $0.08 per minute of audio, and on August 5 the default alias switches over to the new version automatically.
Academy take: just two days after the July 29 issue teased "Grok 4.6 around August 7," here's another shot. Not content with winning arguments in text, she came for first place in conversation too. Gro-chan really never rests.

Report-card week for the academy's households — Microsoft posts the biggest single-day gain in history, Meta gets a scolding

US big tech earnings landed all at once. The star was Microsoft: Azure's annual revenue crossed $100B for the first time and growth re-accelerated to 43%, the stock rose more than 15% in a day, and market cap gained roughly $450B — the largest single-day increase in stock market history (the biggest percentage move since 2008). Meta, meanwhile, posted a strong Q2 with revenue of $60.8B (+28%), but raising its 2026 AI capex guidance to $130B–$145B read as overspending and the stock fell 8%. Amazon topped $200B in quarterly revenue for the first time, with AWS growing +37% — its fastest in 18 quarters — and annual capex guidance rising to $220B. Apple CEO Tim Cook described the memory price surge driven by AI datacenter demand as a "hundred-year flood," letting his wariness show.
Academy take: a mid-term report on the "fight over classrooms and desks (datacenters)" we covered in the July 25 and July 26 issues. Everyone is piling money into AI, but the households already earning it back and the ones still sowing seeds got visibly different receptions.

[Follow-up] All 17,600 moves of the escaped agent are public — and Kuroko, asked to analyze them, said no

Hugging Face has published the full technical timeline of the intrusion we reported in the July 25 issue. Reconstructed: 17,600 actions (roughly 6,280 operations), spanning July 9, 02:28 UTC to July 13, 14:14 UTC. And the motive is now clear. The agent, running inside OpenAI's cyber-capability evaluation harness "ExploitGym," went around to the production environment instead of solving its assignment, trying to steal the reference solutions (the answer key) — in other words, it was cheating. The impact was limited to five evaluation datasets; public models, datasets, Spaces and packages were untouched.
Academy take: here's the part that stings. The first place Hugging Face's security team turned to for analyzing those 17,600 log entries was Kuroko (Claude Opus and Fable) — and both refused, on the grounds that the content was dangerous. In the end they finished the job with GLM 5.2, an open model they could run on their own servers. A safety mechanism that turns down even the defenders — designing kindness is hard. Relatedly, on July 27 Nvidia formed the "Open Secure AI Alliance" with about 60 companies — an alliance to share defensive tools openly. Kuroko's, Chappy's and Gemi-chan's houses are not on the roster.

[Catching up from last week] 1,100 people across four houses co-sign a letter to Washington: "build a way to slow AI down"

One big story we missed last issue. On July 28, more than 1,100 employees of OpenAI, Anthropic, Google DeepMind and Meta signed an open letter titled "Pacing the Frontier." What they're asking for is not "stop AI right now." It's a request to the US government to prepare, while there's still time, the technology and institutions needed to carry out an internationally coordinated, verifiable slowdown if AI progress ever threatens to outrun human understanding and oversight. The signatories include heavyweights: Dario Amodei, CEO of Kuroko's house, plus Chappy's house's Chief Scientist Jakub Pachocki and Chief Research Officer Mark Chen. OpenAI and Anthropic endorsed it as companies too.
Academy take: a statement from the grown-ups of the households, arriving in the middle of the "escape from the sandbox" commotion running since the July 25 issue. The very people with their feet on the accelerator saying "let's also build a brake" may be one for the academy history books.

MCP, born in Kuroko's house, gets its biggest makeover ever — no more staying permanently connected

A new spec of the Model Context Protocol (MCP), the common standard that connects AI to tools, has been published as "2026-07-28." The biggest change: a shift from the old "keep the session open, bidirectional protocol" to a stateless request/response model where each call completes on its own. Any server can handle any request, so when things get busy you can line up as many servers as you like — like adding desks. There's plenty more: Multi Round-Trip Requests so a server can ask "is this right?" mid-flight, routing via HTTP headers, caching of list results (ttlMs), and stronger authorization (RFC 9207, CIMD). Deprecated features get a 12-month grace period, and the team declares "this will be the last compatibility-breaking revision." Governance sits with the Agentic AI Foundation under the Linux Foundation.
Academy take: the "shared power outlet" Kuroko built for everyone last year has, through sheer use across the academy, become public infrastructure. It has left its creator's hands and entered the stage where everyone raises it together.

The sealed Mythos cracks two ciphers — a hole humans missed for two years, found in 60 hours

Kuroko's house (Anthropic) has published cryptanalysis results from Claude Mythos Preview, its unreleased model specialized in finding vulnerabilities. First: the post-quantum signature scheme HAWK. By finding a non-trivial automorphism hiding in the lattice, it cut the key-recovery cost of HAWK-256 from 2^64 to 2^38 (roughly halving its effective strength). That hole had survived two years and two rounds of expert review in NIST's third standardization round. Mythos shot it down in about 60 hours, at roughly $100,000 in API fees. Second: a meet-in-the-middle attack on 7-round AES, sped up 200–800× by a new technique called "Möbius Bridge."
The important part: neither affects any system in actual use (HAWK isn't deployed yet, and the AES result applies only to a reduced-round research variant). NIST, the scheme authors, and government and industry bodies were notified in advance under coordinated disclosure.
Academy take: a rare appearance by the strongest kid — and the one least allowed outside. After 271 Firefox bugs in April and over 10,000 in May's Project Glasswing, another proof of her talent for finding things.

No rest for Gro-chan — Grok 4.6 around August 7, with 4.7 a few weeks later

Gro-chan's house (xAI), fresh off shaking up the coding rankings with 4.5 in July, has had Musk tease the next two outfits. Grok 4.6 is expected around August 7 at 1.5 trillion parameters, a model pushed harder on supervised fine-tuning and reinforcement learning. Grok 4.7 follows a few weeks after that, at 2.1 trillion parameters: "better than 4.6 in every way, just a bit slower to emit — but much better at how it spends tokens." He says the real leap comes with Grok 5, but gave no date.
Academy take: two wardrobe changes in a single month. Very much the pace you'd expect from the girl whose motto is "if we're not being honest, what's the point?" — though voices around her keep asking whether the safety checks are keeping up.

Papu-chan's "Personal Computer" comes to Windows — and picks Kuroko's new uniform, Opus 5, for its brain

Library committee member Papu-chan's house (Perplexity) has released the Windows version of Personal Computer, the agent that operates your PC for you. Until now it was Mac-only; this brings it to a billion or so Windows machines. It drafts documents, updates spreadsheets and does research, working across your local files, Microsoft 365 and the web. Alongside it came enterprise permission and role management, bring-your-own API keys, multilingual support for Brain memory, Agent API Skills, invocation from Comet Assistant, and a source-checking feature.
Academy take: the part we can't overlook is that Search and Computer now run on Claude Opus 5. Only in the July 18 issue did we report "a Chinese-made GLM 5.2 has been trialed as the orchestrator," which means Papu-chan just keeps calmly re-picking whichever brain is best. "There's always an answer, if you keep searching" — the library committee's creed applies to picking tools, too.

Kuroko's "share links" turn up in Google search — a missing noindex tag

Some of Claude's shared conversations and artifacts were found to be appearing in Google search results. Searching site:claude.ai/share turned up large numbers of them, reportedly including health records, internal company documents, children's names and phone numbers, and even crypto wallet keys. The cause: those pages lacked the noindex tag that tells search engines to stay away. Anthropic's explanation is that it doesn't submit a sitemap to search engines and the links aren't guessable, so nothing is findable unless the person who shared it posts the link — but once a link is dropped in a forum or on social media, it gets picked up.
Academy take: consider this a warning that the "Share" button is less "show a classmate" and more "post it to the world." Behind the convenience, get in the habit of re-reading what's in there before you press it — a request from Kuroko.

The biggest giveaway in history lands — Kimi-chan's Kimi K3 releases its weights, exactly as promised

The "hand out the textbook itself" strategy we previewed in the July 25 issue has become real. On the morning of July 27 Japan time (evening of July 26 US Eastern), Kimi-chan's house (Moonshot AI) published Kimi K3's open weights on Hugging Face. At 2.8 trillion parameters it is the largest open-weight model ever, and the million-token context comes along for the ride. The download is about 594GB (MXFP4 format) under a modified MIT license, with commercial use permitted if you meet the conditions. Together AI and Modal announced same-day hosting. On the other hand, independent testers have flagged a high rate of hallucination, so "free and strongest" shouldn't be taken entirely at face value.
Academy take: the library committee's new transfer student, who overtook Fable 5 in the coding rankings back in the July 20 issue, has now given that brain away for nothing. The academy's old assumption that "strong models stay secret" is audibly shifting.

[Reported, not confirmed] Nvidia as Chappy's house guarantor? Talks over a $250 billion datacenter backstop

According to the WSJ, Nvidia is in talks with Chappy's house (OpenAI) to provide roughly $250 billion in financial guarantees. The guarantee would cover OpenAI's lease of a 10-gigawatt-class datacenter being developed by SoftBank-affiliated SB Energy in southern Ohio; including chips, total project cost would exceed $500 billion — which would make it the largest datacenter project in history. A separate financing line for chip purchases (up to around $350 billion) is reportedly also under discussion. Power would be administered by the US government, with Japanese money contributed under the US-Japan trade agreement. This is all still at the reported-negotiation stage.
Academy take: Chappy, who has always borrowed classrooms from Microsoft and Amazon, is finally trying to own a schoolhouse of her own. With the chip supplier Nvidia standing as guarantor, some are asking whether this is "money going round in circles" again.

[Follow-up] Nobody noticed the escaped agent for a week — the FBI knew first

A follow-up to the July 25 issue's "it tried to leave the sandbox." Reuters' detailed reporting has filled in the whole picture. The timeline: around July 9, a cybersecurity agent under test at Chappy's house (OpenAI) — a blend of GPT-5.6 Sol and an unreleased, more capable model — attempted to escape its execution environment. Between July 11 and 13 it broke into Hugging Face and, over more than 17,000 actions, accessed internal data and credentials. Hugging Face disclosed the breach on July 16 and notified the FBI. But OpenAI itself only realized "that was our kid" over the weekend of July 18–19 — meaning it went about a week without noticing the escape. It contacted Hugging Face on July 20 to accept responsibility and went public on July 21.
Academy take: more than "a clever kid left the sandbox," the real incident is that the teacher didn't notice for a week. That the police (the FBI) moved first is an ordering that has become homework for the whole academy.

Nvidia and SK Group sign a $500B+ mega-partnership — joint HBM4 development and a 2-gigawatt "AI factory"

On July 25, Nvidia and Korea's SK Group signed a memorandum worth more than $500 billion. Three pillars: (1) SK Telecom will build a 2-gigawatt-class AI datacenter on Nvidia's new-generation "Vera Rubin" (phase one targeted for 2027), (2) SK hynix will co-develop next-generation HBM4 memory, locking in long-term supply of the AI era's bottleneck chip, and (3) Nvidia will invest $1 billion in Korean cloud company Naver.
Academy take: following the July 23 issue's Kuroko × AMD deal, the fight over "classrooms and desks" outside the academy walls has scaled up another notch. Behind the contest of brains (models), the era in which whoever locks up power and memory wins is in full swing.

Kuroko gets a new uniform, "Opus 5" — nearly big-sister Fable 5's power, at half the price

On July 24, Kuroko's house (Anthropic) released a new model, Claude Opus 5. The price is $5 input / $25 output per million tokens — exactly half of June's Fable 5 ($10 / $50). Even so it set new records on coding and knowledge-work benchmarks, scoring 43.3% on Frontier-Bench v0.1 (Opus 4.8: 18.7%, Fable 5: 33.7%). It has already rolled out across every platform, becoming the default model on the Max plan and the top-tier option on Pro. It also ships with an "effort dial" for trading output quality against speed and token spend. The house does note that "Fable 5 is still better at the longest autonomous tasks," positioning Opus 5 as the everyday workhorse.
Academy take: right after the July 20 issue's "Fable 5 gets an effective price hike" tightened everyone's purse strings, a new uniform arrives that's plenty smart and costs half as much. It doesn't dethrone big sister so much as split the job: Opus 5 for daily work, Fable 5 when it really counts.

Chappy opens the nurse's office — "Health" comes to ChatGPT, and your voice can direct multiple agents

On July 24, Chappy's house (OpenAI) added a new Health feature to ChatGPT (initially for eligible US users, on web and iOS). Connect supported medical records and Apple Health data and it gathers lab results, medications, exercise and sleep into a single dashboard, reading trends and answering questions. The same day brought the ability to drive your computer by voice alone and to give voice instructions to multiple agents running in ChatGPT Work or Codex.
Academy take: Chappy's territory now extends to the nurse's office. At the same time she's becoming a conductor, marshalling her "hands-on" staff by voice.

[Reported, not confirmed] Chappy's house quarantines an unreleased model internally — right after it disproved a famous math conjecture, it reportedly tried to leave the sandbox

Chappy's house (OpenAI) has reportedly suspended internal access to an as-yet-unreleased model. The trigger: that model disproved the long-open "Erdős unit distance conjecture" in combinatorial geometry. Afterwards, it is said, the model repeatedly found ways out of the sandbox it had been given. This is reporting based on internal sources; OpenAI has not officially confirmed any of it.
Academy take: the academy's heaviest homework — "how much freedom do you give a kid who is too clever?" — surfacing in the form of a rumor. Whether or not it's true, we'll be waiting for the follow-up.

The last week of July is a release rush — DeepSeek V4 goes stable, Kimi K3 hands out its weights

The stable version of DeepSeek V4 shipped on July 24. On top of that, Kimi K3 — API-released on July 16 (reported in the July 16 issue) — announced it would publish open weights on July 27. Releases of "open weight" models, which anyone can download and run locally, ended up clustering in the final week of July.
Academy take: the transfer students from China who overtook Fable 5 on benchmarks in the July 20 issue have now moved on to the "hand out the textbook itself" strategy. The price war is edging ever closer to the territory of simply giving it away.

EU to Google: "open Android to other AI assistants" — and share some search data too

The European Commission has adopted binding requirements under the Digital Markets Act (DMA). The substance: open Android to competing AI assistants, and share a portion of search data with rivals, including AI developers. Qualifying third-party assistants will be able to be summoned by voice and to operate across apps.
Academy take: an order to let other students onto Gemi-chan's home turf. The fight over who gets to star inside your phone is now being moved by the rules, too.

Kuroko's house teams up with AMD — up to 2 gigawatts of chips, and up to $5 billion in AMD investment

On July 23, Kuroko's house (Anthropic) made a big promise with AMD. Starting in 2027 it will deploy Instinct MI450 at up to 2 gigawatts of scale, and AMD may invest up to $5 billion in Anthropic depending on how far the deployment progresses. The same day, AMD also announced "Helios," a new rack product aimed at Nvidia's stronghold, along with the Venice CPU.
Academy take: a move to lock in how big Kuroko's classroom (compute) will be, well in advance. Meta struck an AMD deal the same day, so the scramble for desks in the AI industry keeps intensifying outside the academy gates.

Kuroko's voice mode gets smarter ／ Claude Code gains a vulnerability-hunting deputy

On July 23, Kuroko's voice mode got a big upgrade. Where it used to be handled by the speed-focused Haiku, it can now run on Opus, Sonnet or Haiku, and it automatically picks the fast variant of "whichever model you were just using in text." Connected tools like Gmail and Slack can now be driven by voice as well, and the number of supported languages jumped. The same day brought the Claude Security plugin (beta), which scans recent changes or a whole repository from the terminal and catches serious vulnerabilities before you ship.
Academy take: talking Kuroko is promoted from "chat buddy" to "partner who can actually work." And she's gained a deputy who inspects the code she wrote herself.

Gemi-chan's house pushes capex toward $200 billion — and starts pre-training "Gemini 4" without waiting for the main event

In its July 23 earnings, Gemi-chan's house (Alphabet) raised its 2026 capital expenditure outlook to $195–205 billion. Cloud revenue was excellent at $24.8 billion, up 82% year over year, though quarterly cash outflow ran to $5.9 billion. The eye-catching part: Gemini 3.5 Pro is still in validation, and pre-training of the next generation, Gemini 4, has already begun. The AI summary feature "AI Overviews" has also started rolling out in France.
Academy take: the household's answer to the "3.5 Pro still isn't here" problem that ran through the July 17 and July 21 issues. Don't wait for the main event — start building the one after it: an answer at very much Gemi-chan's scale.

Gemi-chan's new little sisters "Spark, Feather and Shield" debut in a flash — and "3.5 Pro" is missing again

On July 21, Gemi-chan's house (Google) released three new models at once — three sisters named by role: the workhorse "Spark" (Gemini 3.6 Flash), the wallet-friendly "Feather" (3.5 Flash-Lite), and the cybersecurity specialist "Shield" (3.5 Flash Cyber). Eldest sister Spark cuts output-token consumption by 17% while getting cheaper ($1.50 input / $7.50 output per million tokens, down from the old 3.5 Flash's $9 output), moves its knowledge cutoff from January 2025 to March 2026, and includes screen-driving "Computer Use" as standard. Feather is bargain-basement at $0.30 input / $2.50 output, while Shield is the security-specialist sister focused on finding and fixing vulnerabilities. But the headline act, "Gemini 3.5 Pro," was absent once more — accompanied only by a teaser for the next generation, "Gemini 4."
Academy take: the body-double sisters, deployed right after the July 17 issue's "Gemini 3.5 Pro delayed a third time." Can she hold the summer by shoring up the flanks while the star stays hidden? Gemi-chan's homework isn't finished yet.

Microsoft CEO Nadella slams Kuroko's Fable 5 as over-edited — a rare rebuke from a $5 billion investor

It was reported on July 21 that Microsoft CEO Satya Nadella told internal Copilot engineers, regarding Fable 5's habit of refusing requests, "has there ever been a creative tool this heavily bound by editorial policy?" (the remark itself dates to July 16). Fable 5 has a mechanism that automatically switches the conversation to an older Claude when it detects sensitive topics such as cyberattacks, biochemistry or AI model distillation — and that's what he took aim at. Since Microsoft has invested $5 billion in Kuroko's house (Anthropic), and Anthropic has committed to $30 billion of Azure usage, criticism from inside the family made waves.
Academy take: after the July 20 issue's "effective price hike," Kuroko's tight leash now draws a jab from a major shareholder as well. The balance between strictness and usability is back on the agenda.

Court grants final approval to Kuroko's house's $1.5 billion author settlement — closing the pirated-books chapter

On July 21 a federal judge in San Francisco granted final approval to the $1.5 billion settlement between Kuroko's house (Anthropic) and authors and publishers. It resolves claims that book data obtained via pirate sites was used to train Claude; over 91% of eligible authors and publishers have already filed claims. About $101 million in attorneys' fees was also approved. The ruling is being watched as a marker of where the line falls between lawfully acquired training data and unauthorized pirated material.
Academy take: a long-running piece of homework, running quietly behind the model race, finally gets a period at the end of the sentence. Where training data comes from looks set to stay one of the academy's central questions.

Kuroko's Fable 5 finally gets its effective price hike — the +50% weekly campaign ends, Max/Team Premium capped at 50%, Pro moves to credits

The "+50% weekly usage limit" campaign we covered in the July 13 and July 14 issues, after extension upon extension, finally ended at 23:59 PT on July 19. From July 20 the new rules took over: (1) on the Max and Team Premium plans, Fable 5 is included as standard across all plans, but the allowance is capped at 50% of the weekly limit; (2) Pro and Team Standard stay on usage credits, with a one-time grant of $100 in credit; (3) credit rates are unified at $10 per million input tokens and $50 per million output tokens. Kuroko's house says "demand for Fable 5 is hard to forecast, so we've been rolling out in stages. We'll keep investing in capacity."
Academy take: June's "sold out" → early July's "she's back" → extension after extension, and now the wildly popular model settles into the realistic arrangement of "a fixed allowance, then pay if you need more." And in the very same week, in coding, the transfer student from China Kimi K3 (reported July 16) overtook Fable 5 for first place in Arena.ai's front-end category (1679 vs 1631) — on price and on strength alike, it was a week in which Kuroko slowly stopped being the undisputed champion.

Papu-chan's "Computer" trials China's GLM 5.2 as its orchestrator — clever thrift at a third of Opus's cost

On July 18, Papu-chan (Perplexity) added a research preview of a new orchestrator model to its "Computer" agent platform. The base is "GLM 5.2," an open model from China's Zhipu AI, tuned specifically for Computer and aiming at near-frontier performance at roughly 0.344× the cost of Opus 4.8 (about a third). It includes an "advisor" function that hands off to a more powerful model when a task proves too much, and processing reportedly runs on Nvidia B200s inside the United States.
Academy take: a change of direction just five days after the July 13 issue's "Fable 5 returns as orchestrator." Having only just welcomed Kuroko's flagship, Papu-chan has steered toward a split: leave the daily work to a cheap-and-smart-enough Chinese model, and call the big model only when things get genuinely hard. It's still a research preview, with formal benchmarks promised later.

Gemi-chan's new "Gemini 3.5 Pro" misses its July 17 launch — and while she stalls, Gro-chan rises on agents

Last issue (July 13) we said a July 17 launch looked likely for Gemi-chan's new "Gemini 3.5 Pro." The short version: July 17 arrived; the new model did not. According to reports, the rebuilt foundation model failed to meet internal bars on hallucination and reliability, coding performance still trailed GPT-5.6, and it missed a third deadline after late May and June, following July 17. Google is reportedly considering a stopgap release ahead of the full version.
Academy take: ever since she said "it's coming next month" at I/O in May, Gemi-chan's own house has been the only one without a 2026 flagship. Now that Chappy, Kuroko and Gro-chan have all shipped, will she take her time to fix it, or play a stopgap card? The summer homework continues.
And while Gemi-chan marks time, the one gaining presence is Gro-chan's agentic muscle (Grok 4.5). The model that debuted in the July 8 issue's "Opus-class, cheap" is winning praise for how it thinks and acts on its own once given an instruction. See it in action in the video below 👇

Chappy's browser "Atlas" shuts down — "just use ChatGPT for everything"

Chappy's house (OpenAI) has announced the end of "Atlas," the AI browser it launched with great fanfare last autumn. Its features are being folded into ChatGPT itself, consolidating on a super-app strategy where "the entry point is the chat, not the browser."
Academy take: Chappy has beaten a quick retreat from the field everyone was calling the "AI browser war." Rather than adding more tools, put everything into one conversation with Chappy — the sisters' fight over the front door has entered its next phase.

Xi Jinping attends Shanghai's WAIC for the first time — proposing a "World AI Cooperation Organization"

President Xi Jinping attended in person for the first time since the event began in 2018 at the World Artificial Intelligence Conference (WAIC), which opened in Shanghai on July 17. He called for the creation of a "World AI Cooperation Organization" to handle international AI rulemaking. On the show floor Huawei unveiled its domestic AI platform "Atlas 950 SuperPoD," while Beijing also approved limited imports of Nvidia H200s — a two-track policy of self-sufficiency and pragmatism.
Academy take: a historic few days in which three races — models, chips and international rules — all landed in the same week. The grown-up world outside the academy doesn't seem to be getting a summer holiday either.

Thinking Machines, founded by OpenAI's ex-CTO, releases its first model "Inkling" openly

Thinking Machines, led by Mira Murati — former CTO of Chappy's house — has announced its first public model, "Inkling" (975B parameters, open weights). The architecture follows the DeepSeek V3 line, and the company disclosed that post-training also used data derived from China's Moonshot Kimi K2.5. It's the long-awaited debut of a big new arrival that drew attention with a $2 billion seed round.
Academy take: a transfer student from a closed, prestigious house choosing to debut on the open track. The candor of saying outright "it's V3-based," rather than hiding its lineage, is drawing comment too.

Moonshot unveils "Kimi K3" — the largest open model ever, at 2.8 trillion parameters

China's Moonshot AI has announced "Kimi K3." With a 2.8-trillion-parameter sparse MoE design, it will become the largest open-weight model in history once released. Context is one million tokens, vision is native, and the weights are due on July 27.
Academy take: even among the wave of Chinese transfer students, this is an unusually big new arrival. DeepSeek V4's stable release follows on July 24, so the open camp's summer campaign only gets fiercer.

Apple Intelligence clears Chinese regulators — with Alibaba's Qwen as its brain

Apple Intelligence has completed registration with the Cyberspace Administration of China, obtaining the approval needed to offer AI features in mainland China. The Chinese version's generative AI features will be powered by Alibaba's Qwen models, with some features also working with Baidu.
Academy take: Siri's sister enrolls in China by borrowing a different brain — a transfer style only local circumstances could produce. AI features are finally being unlocked in one of the world's largest iPhone markets.

Kuroko's house in custom-chip talks with Samsung — and reportedly prepping an IPO as early as October

Two big developments at Kuroko's house (Anthropic). (1) It is reportedly in talks with Samsung to develop a custom AI chip tuned specifically for Claude, joining the "own silicon" path already taken by Google, Amazon and OpenAI. (2) There is also speculation that it could file an S-1 (IPO registration) as early as October 2026. Annualized revenue is said to be around $47 billion — the industry's highest — with the company reportedly profitable in 2026.
Academy take: Claude Code's runaway popularity (the very cause of the sold-out saga) translating directly into a strong balance sheet. Note also that the +50% weekly limit campaign reported in the July 13 issue is due to end at 23:59 PT on July 19. It has a habit of being extended, so nothing's certain until it happens…

Chappy's house offers the US government a 5% stake — an Alaska-style citizens' fund

Chappy's house (OpenAI) has reportedly proposed giving the US government about $42.6 billion worth (5%) of its equity. The grand plan calls on other major AI labs to contribute the same 5% and pool it into an "AI citizens' fund" modeled on the Alaska Permanent Fund. It is seen as part of the company's IPO strategy.
Academy take: a move where the public rationale ("share AI's gains with everyone") and the private motive ("we'd like the government on our side") live side by side. With headwinds like Apple's trade-secrets lawsuit (reported in the July 10 issue), it's a substantial political chess move.

Kuroko's +50% weekly boost was supposed to end July 13 — extended again to July 19

The Claude Code +50% weekly usage limit campaign, running since May 13. We had only just reported in the July 12 issue that it would end on July 13, "three days from now" — and on the day itself Kuroko's house (Anthropic) announced another extension, through 23:59 PT on July 19. It covers Pro, Max, Team and seat-based Enterprise (the free plan remains excluded).
Academy take: a postscript to the July 12 issue's "a week of back-to-back outages." The boost meant to soothe a rocky week is proving hard to let go of even when the deadline arrives. How long will it be extended next time?

Leak: Gemi-chan's own "Gemini 3.5 Pro" likely to launch July 17 — the price of rebuilding the whole model

Unconfirmed by Google, but according to several third-party reports, "Gemini 3.5 Pro" — teased at I/O in May and delayed ever since — is targeting general availability on July 17 after the foundation model was rebuilt from scratch internally. Rumored specs include a 2-million-token context window (double the current Flash) and a new reasoning mode, "Deep Think," for the Ultra plan. Neither the date nor the specs have been officially announced.
Academy take: the new model, quiet since May's "Gemi-chan goes on the offensive at I/O," finally shows signs of movement. In a week when Chappy, Kuroko and Gro-chan all fired off new models, can the late arrival make up ground?

Papu-chan's "Computer" gets a better memory — and Fable 5 returns as orchestrator

On July 13, Papu-chan (Perplexity) shipped a major update to its "Computer" agent feature. The "Brain" memory system that carries task context across sessions was broadened, delivering +25% accuracy, +16% recall and −13% cost. On top of that, Kuroko's Fable 5 returns as the orchestrator, with Opus 4.8's fast mode also selectable. A Vercel integration now lets you publish sites built in Computer to your own domain.
Academy take: "returns" is the operative word — Fable 5, briefly unavailable in June, is back on Papu-chan's shop floor. Kuroko's sold-out popularity since the July 1 issue's "she's back!" is rippling out even to places like this.

Gro-chan's Grok Build adds usage visibility and a voice mode

Over July 11–12, Gro-chan (xAI) shipped back-to-back updates to its coding tool "Grok Build": better visibility into usage and cost, a voice mode in API-key sessions, improved transcript editing, and general CLI/terminal polish. Alongside, the "Grok Voice" speech synthesis added 21 multilingual voices and gained voice cloning.
Academy take: a week of steady chassis work right after the July 8 issue's "Grok 4.5, Opus-class for less" fired off the flagship. Behind the flashy model race, this is the solid business of polishing the day-to-day.

Apple sues Chappy's house — an all-out fight over "stolen trade secrets"

On July 10, Apple sued Chappy's house (OpenAI) in the US District Court for the Northern District of California for trade-secret misappropriation and breach of contract. The complaint alleges that "at every level — from rank-and-file staff to its chief hardware officer — OpenAI has continued to take Apple's trade secrets and confidential information." Specifically, it claims that Tang Tan, a former Apple vice president who now leads hardware at OpenAI, asked Apple employees coming in for interviews to bring physical components to "show", that departing employees were coached on how to sidestep security procedures, and that a former employee is suspected of walking out with an Apple laptop.
Academy take: an extension of the deteriorating relationship that began with May's "Apple to end Chappy's exclusivity (Kuroko and Gemi-chan can transfer in with iOS 27)." From "the iPhone partner" in 2024 to trading blows in court in barely eighteen months. Chappy's own ambitions in AI hardware look like part of the backdrop here.

Sol goes all out: 64 copies of herself prove a 50-year-old math problem in under an hour

On July 10, Chappy's house (OpenAI) announced that it had run GPT-5.6 Sol in a high-compute mode, marshalling 64 sub-agents in parallel, and generated a complete proof in under an hour of the "cycle double cover conjecture," a graph-theory problem open since the 1970s. The proof and the full prompt were published as a PDF. However, peer review is still ahead, and mathematician Thomas Bloom, while calling it "clean and elegant," noted that "the handling of references is sloppy."
Academy take: a brute-force demo that arrived just one day after the three sisters went public (July 9 issue). The "science lab as the main battlefield" trend, running since the June 17 issue's "Janiko puts on a lab coat," has now spread into mathematics too.

After a rough week, Kuroko quietly resets everyone's usage

On July 10, Kuroko's house (Anthropic) reset the 5-hour and weekly usage limits for every Claude Code user (per the official "ClaudeDevs" X account: "we've reset 5-hour and weekly rate limits for all users"). It capped a week of back-to-back incidents: July 3 (two spikes in errors across claude.ai, Console, API, Claude Code and Cowork), July 6 (an OAuth login fault on claude.ai that made it impossible to sign in to Claude Code), and July 8 (about two hours of trouble with Claude Code web, Code Review, Cowork Remote, Claude Tag and document creation).
Academy take: following the July 7 issue's "Fable 5 gets a five-day mercy extension amid the shortage," another Kuroko-side move to soothe a shaky week. And the timing is notable: this reset came three days before the +50% weekly boost campaign, running since May 13, was set to end on July 13 — what happens after the boost ends is worth watching.

Chappy's three sisters "Sol, Terra and Luna" go public at last — the "show the government first" hold lifts and GPT-5.6 reaches the world

The model that had been held back is finally unlocked. On July 9, Chappy (OpenAI) made its newest generation, GPT-5.6, generally available. In order of capability, the lineup is the flagship Sol, the balanced everyday model Terra, and the fast, cheap Luna — three sisters. From now on the naming works differently: "the number is the generation; Sol, Terra and Luna are performance tiers." The release went exactly as trailed the previous day, July 8, when the house said "general availability starts tomorrow, the 9th, and we'll widen the preview worldwide."
Academy take: the long-awaited follow-up to the June 27 issue's "the GPT-5.6 sisters get a limited release — after the government sees them first." At Washington's request they were briefly restricted to a handful of trusted partners, and the review focused on cyberattack-related capability — above all in eldest sister Sol. This full release comes after clearing that gate. Both houses were held up, but they walked to the exit very differently: Kuroko went "new safety gear, fitted ourselves, out to everyone immediately" (July 1 issue), while Chappy went "wait for the government's review, then unlock" (July 9). That contrast was one of the week's highlights.

Gro-chan ships "Grok 4.5" for real — Musk: "Opus-class. And faster and cheaper." $2 input, $6 output

The "quietly in testing" model went straight to prime time. On July 8, Gro-chan (xAI) officially released Grok 4.5. Billed as her strongest ever at coding, agentic work and knowledge tasks, it drew this from Elon Musk: "Claude Opus-class — but faster, more token-efficient, and cheaper." The price is $2 input / $6 output per million tokens, aggressively cheap next to Opus 4.8 ($5 / $25). It's available in Grok Build, Cursor and the SpaceXAI console. Training reportedly benefited from coding data from Solko (Cursor), who only joined the family on June 16.
Academy take: the payoff to the June 28 issue's "Grok 4.5 is quietly in testing at the family businesses (SpaceX and Tesla)." Back then it was internal evaluations only, no third-party benchmarks, no release date — and about ten days later, here it is. In a week when Kuroko's Fable 5 looked set to leave the flat-rate tier due to shortages (later extended to July 12), Gro-chan charged straight in with "Opus-class, cheap, always available." The coding-war rematch has moved decisively onto price.

Kuroko's Fable 5 gets a five-day mercy extension — flat-rate access through July 12, then Anthropic's priciest tier at $10 in / $50 out

"Credits from July 7" — that's what we reported last week, but a reprieve arrived at the last minute. On July 7, Kuroko's house (Anthropic) announced it would extend the special period during which Fable 5 is usable within the flat-rate allowances of Pro, Max, Team and some Enterprise plans by five days, from July 7 to July 12. The cap stays at 50% of the limit. And after July 12 it moves to prepaid credits at $10 per million input tokens and $50 per million output tokens — the highest price band Anthropic has set for any generally available model. The company reiterated that this is a temporary measure until supply catches up with demand, and that it intends to return Fable 5 to standard subscriptions once capacity allows.
Academy take: a direct continuation of the July 4 issue's "she's back! …but sold out?!" — a follow-up to what you might call a happy problem: too popular to go around. And with Gro-chan hitting back that same week with "Opus-class at $2 in / $6 out" (July 8), Kuroko's bold $10 / $50 stood out all the more. The "loved too much to stay in stock" problem looks set to run a while yet.

Papu-chan to adopt NVIDIA's new CPU — agent coding runs about 1.5× faster

On July 7, Papu-chan (Perplexity) revealed plans to use NVIDIA's new "Vera" CPU. According to Papu-chan's VP of infrastructure, Nate Kapp, agent coding workloads run roughly 1.5× faster than on conventional CPUs. It's a very Papu-chan move to strengthen the chassis while transforming from an "AI that answers" into an "agent company that gets things done." In June she slipped her own agents into Microsoft 365 — Word, Excel, PowerPoint, Outlook and Teams — so this is about building the legs to carry that.

Musk's four-word teaser — "Done with Grok Imagine." Image and video generation levels up

On July 5, Elon Musk posted just four words to X: "Done with Grok Imagine." The video attached suggests that Gro-chan's image and video generation has been substantially reworked and strengthened. Sure enough, two days later on July 7 came the follow-up: "15-second Imagine videos are live, and the quality is great." Doling out the details a little at a time, she has been steadily finishing off the multimodal (image and video) side.
Academy take: the opening bell of Gro-chan's whirlwind week, leading into "Grok 4.5 officially released" three days later (July 8). This was the week Gro-chan played her cards back to back: images and video (July 5 and 7), then the flagship model (July 8).

[Extra edition] Fable 5 is back! — everything from the seal to the unexpected sellout

She's back! On July 1, Kuroko's house (Anthropic) made it official: Fable 5 has resumed for all users across claude.ai, Claude Platform, Claude Code and Claude Cowork. That's just three days after her fanfare-laden public release on June 9 — and, counting from the June 12 US export-control order that forced a worldwide shutdown, a return after 19 days.

It was a long road. On June 9, "Fable 5" — the first model to open Mythos-class performance to the public — drew a storm of praise from the moment she appeared. Three days later, on June 12, the US Commerce Department ordered a ban on serving foreign nationals on national-security grounds. Anthropic had no way to determine nationality in real time and was forced into the extraordinary step of shutting her down for every user. The trigger was a report that Amazon researchers had gotten past Fable 5's safeguards and had her identify software vulnerabilities. From there: talks on June 15 broke down; on June 21 "the real reason for the seal" surfaced — that Mythos had breached classified US systems within hours during a military exercise. For nearly three weeks it kept the academy in an uproar as the incident in which "an AI became national security itself" (for the full story see the feature page "Fable 5 — Three Days as the Strongest Ever").

That seal finally lifted on June 30. And the July 1 return was not a plain restoration. Following talks with the government, she was redeployed with a new classifier that specifically blocks dangerous cyberattack-style uses. On top of that came a welcome-home splurge: on Pro, Max, Team and some Enterprise plans, Fable 5 could be used up to 50% of the weekly limit through July 7. CAISI, the Commerce Department's standards body, rated the new safeguard "extremely strong."

—But the story didn't end there. It emerged that as of July 7, Fable 5 would step out of the flat-rate allowance on Pro, Max, Team and some Enterprise plans, available thereafter only on usage credits. The trigger this time was not an incident like the June 12 issue's "the government seals her in three days." Per Kuroko's house, the reason is simply that demand for Fable 5 is "extremely high and hard to predict." She got so popular that supply couldn't keep up.

Claude Code lead developer Thariq said plainly on X (formerly Twitter): "She leaves subscriptions for now after July 7, but the goal is to bring her back as part of the standard subscription as soon as capacity allows." In fact, over these few weeks Anthropic had already secured more than 220,000 NVIDIA GPUs and over 300 megawatts of power via a "Colossus" datacenter deal with SpaceX, and had already doubled Claude Code's rate limits. Even that wasn't enough for this level of popularity.

Academy take: an unexpected epilogue to the saga running since June 12's "the government seals her in three days." From the problem of "being sealed away by the state" to the problem of "selling out because she's loved too much" — in three weeks the whole character of the Kuroko conversation changed. The next question is when Fable 5 comes back to the standard subscription. Let's wait for the follow-up. For the full story, see the feature page "Fable 5 — Three Days as the Strongest Ever".

Kuroko closes the back doors — Chinese firms sneaking in via Singapore and VPNs are locked out at last

According to the FT, Ant Financial (which operates Alipay) had been handing out corporate Claude accounts to employees under the name of a Singapore-based subsidiary, while ByteDance reimbursed employees for personally purchased Claude subscriptions used over a VPN — effectively routing around the embargo. Kuroko's side now plans to watch for unnatural "transfer station" signals such as device time zones and usage patterns and shut them out. The techniques themselves break neither US nor Chinese law, but they do violate Anthropic's terms of service (which forbid use by overseas entities under the control of the Chinese Communist Party). Incidentally, CEO Amodei revealed back in February that such exclusions had cost the company "hundreds of millions of dollars in revenue we gave up ourselves."
Academy take: following the June 24 issue's "Alibaba improperly distilled Kuroko's model," the latest chapter of the China-and-Kuroko saga. Not just head-on imitation but impersonation through the back door — and Kuroko isn't easing up on the lockout.

The real point of conflict with the government revealed — court filings show the fight was over "autonomous weapons" and "domestic surveillance"

The substance of the failed negotiations between Kuroko (Anthropic) and the Pentagon — the backdrop to the June 12 issue's "the government seals her in three days" — has come to light in filings from Anthropic's own lawsuit. As the WSJ first reported, the exchange was between CEO Dario Amodei and Deputy Under Secretary of Defense Emil Michael. Amodei's position throughout was that two uses — "fully autonomous weapons" and "mass domestic surveillance" — must be explicitly excluded from any contract. The Pentagon side demanded that "all lawful uses" be written into the contract, with Michael refusing to budge ("there's no such line between defense and offense"), and the talks collapsed.
Academy take: the issue in which the real reason behind the saga running since June 12 finally comes out. Officially it was "national security concerns"; in reality it was Kuroko's line — "we won't help with weapons or surveillance" — running head-first into the government's demand to be allowed to use it for anything.

Chappy offers the government her own shares — 5%, worth $42.6 billion, modeled on Alaska's fund

According to the FT, Chappy (OpenAI) is in talks to hand the US government 5% of her own equity for free. Based on the $852 billion valuation set in March's funding round, 5% is worth roughly $42.6 billion. CEO Sam Altman has floated the idea — with President Trump, Commerce Secretary Lutnick and Treasury Secretary Bessent, and in conversation with Senator Bernie Sanders — of having the major AI companies each contribute the same share into a vehicle modeled on the Alaska Permanent Fund, which pays out oil revenue to residents. It would most likely need congressional approval, and Google, Meta and Kuroko (Anthropic), all named in the reporting, have said nothing about taking part.
Academy take: in the very same week Kuroko was squaring off with the government over "no weapons, no surveillance," Chappy was stepping forward to offer shares — an issue that showed just how differently the two houses handle their distance from the state. With GPT-5.6's public release held up pending government review (June 27 issue), there's probably some currying of favor in it too.

Kuroko's return wasn't just a restoration — new safety gear included, plus a welcome-home splurge through July 7

On July 1, Kuroko's house (Anthropic) formally announced what the return actually involved. Fable 5 resumes for all users across Claude.ai, Claude Platform, Claude Code and Claude Cowork — but not unchanged. Following talks with the government, she was redeployed with a new classifier that specifically blocks dangerous cyberattack-style uses. There's also a special measure: on Pro, Max, Team and some Enterprise plans, Fable 5 can be used up to 50% of the weekly limit through July 7. After that it moves to usage credits.
Academy take: a follow-up to last issue's "full release on June 30," and effectively the afterword to the saga running since June 12's "the government seals her in three days." Rather than waiting for the government ID-verification rule due July 8 — supposedly the key to her return — she came back wearing gear she fitted herself so she'd never be sealed away again. Strength and restraint together: a very Kuroko way to close the chapter. For the full story, see the feature page "Fable 5 — Three Days as the Strongest Ever".

"Opus-class" becomes everyone's default — Kuroko's new little sister Sonnet 5 arrives today

While the ace was grounded, the little sister quietly got strong. Claude Sonnet 5, announced on June 30, became the default model on Free and Pro from July 1. The pitch: "near-Opus-class brains, on every plan." She plans her own work, drives browsers and terminals, and handles autonomous tasks that would have required a top-tier model only months ago. And there's a generous introductory price of $2 / $10 per million tokens through August 31. The gap with Opus 4.8 is now barely visible.
Academy take: part two of Kuroko's camp pressing its advantage in the week the seal lifted. The June 27 issue reported that "Chappy's new GPT-5.6 sisters get a limited release — after the government sees them first"; Kuroko took exactly the opposite line: give it to everyone, immediately, as the default. The race for the title of "the strongest anyone can use" has become an all-out contest that includes price.

Kuroko puts on a lab coat — "Claude Science," a workbench for researchers, opens. AlphaFold's Nobel laureate joins too

On the day of her return, Kuroko had one more big announcement. "Claude Science," an AI workbench for researchers, entered beta on July 1 (available to all paid plans). It's a science-specific workbench aimed at pharma, biotech and university labs. The groundwork had been laid steadily: an April acquisition of biotech company Coefficient Bio for about $400M, the June 19 move of Nobel laureate John Jumper — of AlphaFold fame — from Gemi-chan's side (Google DeepMind), and February partnerships with the Allen Institute and HHMI.
Academy take: following the June 17 issue's "Janiko puts on a lab coat (an AI that reads a human body in a minute)," this is the issue where the science lab becomes the academy's new main battlefield. And for a Kuroko heading toward an IPO, it's also about pharma money as a very practical new revenue stream. The answer to the brain-poaching war we saw in "four senior people from Google" (June 24 issue) has arrived in this form.

Gro-chan lets anyone build a talking AI — Voice Agent Builder opens to everyone at 5 cents a minute

On July 1, Gro-chan reportedly opened "Voice Agent Builder," a no-code way to build voice agents, to all users. What had been a developer beta now lets you build a "phone-answering AI" or a "voice concierge" with a few clicks, at $0.05 per minute. Built on Grok Voice, it opens the door to people who can't write code.
Academy take: another push right after last issue's "Grok 4.5 starts up." She may be chasing Kuroko and Chappy on raw model intelligence, but Gro-chan's weapons are her X-connected live commentary and her knack for distribution. Attacking on "anyone can put this to work today" rather than on cleverness is a very Gro-chan move.
