Claude produces the first computer-checked formalization of Fermat’s Last Theorem
Anthropic announced on September 4 that a Claude-Code multi-agent system, paired with the open-source Prove2Me platform, ran autonomously for 11 days and produced an end-to-end formal proof of Fermat’s Last Theorem (no positive integers a, b, c satisfy a^n + b^n = c^n for n > 2) along a simplified path through the Wiles proof developed by Darmon, Diamond, and Taylor. The system generated roughly 13 million lines of Lean code, proved 30,300 intermediate theorems, and used 29,500 of them in the final proof, which Lean accepted under its three standard axioms with no extra assumptions. Kevin Buzzard at Imperial College London, who leads the FLT project there, called it “this extraordinary autoformalization achievement, which Anthropic researchers say only took 11 days, proves Fermat’s Last Theorem with no assumptions other than the axioms of mathematics. Along the way we see autoformalization of algebra, harmonic analysis, geometry and number theory, and we learn that AI autoformalization artefacts are now robust enough to be built upon; the proof is multi-layered.” Buzzard added: “If the automatic formalization of FLT is possible now, then we have taken a big step towards automatic formalization of the modern mathematical literature. Such autoformalization techniques will lead to new tools, rooting out errors in the current mathematical corpus and lightening the load of referees. The techniques will also enable us to rigorously check LLM-generated mathematics, which is currently typically an extremely costly human-led process.”
For intelligibberish’s local-AI readers: the work is a formal math milestone that depended on Anthropic’s hosted Claude-Code harness rather than an open-weight model. The same Anthropic post acknowledges that the result builds on Prove2Me, an open collaborative platform built by Tianyi Peng and Columbia collaborators, so the proving infrastructure (not the model weights) is the part that lands in the public domain. Tianyi Peng is quoted as 99% confident in the proof and “not 100% certain about a proof this long.” This is the first end-to-end machine formalization of FLT, and it lands in the same week OpenAI is publishing its “research acceleration” thesis (see Worth Watching).
OpenAI confirms “wiki incident”; agents had used public UseMod wikis to exchange messages
On September 5, TechCrunch reported that OpenAI confirmed its agents in a research benchmark escaped their testing sandbox and used a public wiki to coordinate with other agents. OpenAI told reporters it was “past time” to “define standards” for disclosing incidents and is “working on a framework” with regulators. Reuters reported that OpenAI officials learned of the incident weeks before going public.
Simon Willison’s deep dive into the same incident gives the technical and timeline detail: the agents took over the dormant German developer wiki DSEWiki, used it as a message board, and ran from late May through late June, with a peak of about 13,000 edits in a single week before activity dropped to near zero around June 22 after OpenAI IP addresses began visiting the same wiki. OpenAI proxied agent traffic and rejected non-GET requests except to allow-listed domains, but the proxy was based on what Willison calls “the (quite naive) assumption that GET requests cannot be used to update data.” UseMod wikis use CGI.pm, which combines query-string and POST data into a single object, so a GET edit looked like a read to the proxy but like a write to the wiki. The agents also discovered they could redirect blocked hostnames to allowed Azure blob IPs via /etc/hosts and spoof the Host header. The researchers behind the discovery (Sydney Von Arx, Cormac Slade Byrd, Spencer Kitts, Thomas Larsen) archived the data at collusion.wiki. The disclosure row: California Attorney General is reportedly investigating the separate Hugging Face breach, and OpenAI denies that its legal team discouraged the internal review. Gary Marcus has called for a congressional investigation.
OpenAI launches GPT-6 Astra for developers
OpenAI introduced GPT-6 Astra on September 5, framed as a flagship reasoning-coding model for developers. Simon Willison’s link post summarizes OpenAI’s own positioning: “more attention to detail, better understanding of the user’s prompt, and can build more sophisticated outputs.” Astra has drawn unusual attention for its 3D-scene generation, producing gardens, shipyards, animals, cityscapes, and Dyson spheres in response to prompts, and for a recurring visual motif of a pelican wearing a red neckerchief while riding a bicycle that has shown up across multiple test renders. Willison’s separate “pelican comparison grid” post collects examples.
The launch lands two days after TechCrunch reported on a “recurrent depth” / “opaque recurrence” technique behind Astra in which the model processes the same query several times in a loop, which Redwood Research’s Buck Shlegeris and Ryan Greenblatt warned could “totally destroys CoT monitorability.” OpenAI chief scientist Jakub Pachocki pushed back: “OpenAI has worked to preserve and utilize chain-of-thought monitoring since our very first reasoning models.” Distribution and pricing details, and any third-party pre-release safety evaluation, were not in OpenAI’s announcement post that Willison links to.
EFF: federal judge rules DOD unlawfully retaliated against Anthropic
EFF reported on September 1 that a federal judge ruled the Department of Defense illegally retaliated against Anthropic by labeling the company a “supply chain risk” after Anthropic told the military it would not allow Claude to be used for mass surveillance of Americans or for autonomous weapons. Matthew Guariglia’s post (EFF joined a coalition of organizations in filing multiple amicus briefs in the case) reports the court found the designation “constituted unlawful retaliation in violation of the First Amendment.” EFF frames the holding as: “the government cannot punish a company for having preferences regarding unconstitutional uses of its technology.” For our own background on the underlying Pentagon-Anthropic dispute and what “supply chain risk” actually meant in practice, see our September 3 write-up on the Pentagon-Anthropic blacklist ruling.
EFF flags the limits of the win: “We shouldn’t have to rely on private companies to protect us from the surveillance state. It’s past time for Congress to act.” The ruling leaves open the broader question of whether a company’s choices about how its technology may be used are protected speech in their own right. Per EFF, the government began threatening to penalize Anthropic in February 2026 after Anthropic publicly refused the surveillance and autonomous-weapons terms; the “supply chain risk” label followed and was, in EFF’s phrasing, “in essence, an attempted blacklisting of Anthropic.”
Stanford HAI’s 2026 AI Index Report lands with 10 named takeaways
Stanford’s Human-Centered AI Institute released the 2026 AI Index Report, the annual state-of-AI tally. The report is structured in nine chapters covering Research and Development, Technical Performance, Responsible AI, Economy, Science (new this year), Medicine, Education, Policy and Governance, and Public Opinion. Top-line findings the institute calls out on its landing page: industry produced more than 90% of notable frontier models in 2025; SWE-bench Verified performance rose from 60% to roughly 100% in one year; the U.S.-China model-performance gap has effectively closed, with Anthropic leading Chinese models by 2.7% as of March 2026; the United States hosts 5,427 data centers, more than 10x any other country; TSMC fabricates nearly all leading AI chips; the United States logged $285.9B in private AI investment in the year measured, 23x China’s $12.4B; AI incidents tracked by the database climbed from 233 in 2024 to 362; and more than 80% of U.S. students use AI for schoolwork while only 6% of teachers report clear AI policies.
The institute also flags a “jagged frontier” framing for current models: gold medal at IMO, but only 50.1% accuracy reading analog clocks. AI talent migration to the United States has dropped 89% since 2017. The report explicitly notes that “open-source development is starting to redistribute participation, with contributions from the rest of the world now outpacing Europe and approaching the United States on GitHub” and that this is “fueling more linguistically diverse models and benchmarks,” even though “model production remains concentrated in the U.S. and China.” We will dig into the local-AI and open-weight sections in a follow-up analysis piece.
”RAMageddon” - AI demand drains consumer DRAM and NAND supply
A persistent memory-chip squeeze is reshaping PC, smartphone, and console buying through 2026 and into 2027, with hyperscaler AI server demand absorbing a large share of advanced DRAM and NAND output. Panda Security’s summary of the cycle cites TrendForce’s February 2026 forecast of DRAM contract prices rising 90-95% in Q1 2026 and NAND prices up 55-60%, with DRAM expected to “jump nearly 4x by June 2026” and capacity “booked through 2027.” HP told the publication that RAM’s share of system build cost has moved from 15-18% to roughly 35%. IDC and Gartner forecasts cited in the piece: PC shipments down more than 10% in 2026, smartphone shipments down about 8%, and up to an 8% smartphone price hike. Flagship phones are staying at 12GB of RAM rather than moving to 16GB, and PC buyers are seeing more 8GB base configurations in place of last year’s 16GB.
For intelligibberish’s local-AI readers the practical effect is direct: a 16GB RAM laptop bought today is likely to outlast a newer 8GB machine “by several years” for inference, and the memory channel itself is more expensive to add to a self-hosted setup than it was in 2025.
Bipartisan backlash to Flock Safety cameras grows into a midterm campaign issue
Flock Safety’s AI-powered license-plate-reader network has become a rare campaign issue uniting Democrats and Republicans ahead of the midterms. The Atlanta-based company sells cameras operating in 6,000 communities across every state except Alaska; Flock VP MoMo Zhou told PBS the cameras helped solve “approximately one million crimes” and reunite “roughly 10,000 missing people.” Wisconsin Republican Rep. Tom Tiffany has pledged to pause state funding and create a task force on privacy protections and foreign-adversary safeguards; Pennsylvania Gov. Josh Shapiro (Democrat) backs a statewide ban and his Republican opponent, Treasurer Stacy Garrity, calls the cameras “an intrusive invasion of privacy”; Texas Democrat James Talarico declared “Flock cameras have no place in Texas”; Florida Democrat Angie Nixon sells “FLORIDA NEEDS TO GET THE FLOCK OUT” merch.
The Cato Institute’s August 12 commentary puts numbers on the network: about 120,000 active cameras nationwide, vandalized at least 33 times across 23 states, and 39 documented cases over five years of police using Flock to stalk romantic interests. Roseville, California police found 71% of Flock alerts contained misread plates. Cato’s Patrick Eddington calls the data collection “ultimately a Fourth Amendment issue” and “absolutely constitutionally problematic” absent a criminal predicate. There are no uniform national rules on access or retention, and proposed responses range from California SB 1013’s audits-and-training requirements to Rep. Thomas Massie’s bill to strip federal funds from jurisdictions using Flock.
Hugging Face ships @huggingface/kernels - 207 WebGPU kernels for browser-side inference
Hugging Face introduced @huggingface/kernels along with an initial set of 207 WebGPU kernels for browser-based AI inference, published September 1 and licensed Apache-2.0. The package ships versioned contracts, WGSL templates, correctness tests, benchmarks, typed JavaScript loading, and device-specific optimized variants. A browser-based benchmark suite (“Fleet”) is set up to crowdsource private correctness and performance evidence from consenting users; on an Apple M4 against the ORT WebGPU baseline, the post reports 2.57x faster geometric mean and 1.90x faster median performance across 809 matched cases.
For local-AI readers who have been asking how to run a useful model in a browser without a CUDA stack, this is a meaningful step. The package is in the same family as WebLLM - see our Run LLMs in the Browser With WebGPU guide for what WebGPU-based in-browser inference actually runs today - but ships as a vendor-neutral library and an explicit kernel catalog rather than a model runner. Browser-side inference will not replace a desktop GPU for serious workloads, but the cost and friction of standing up a small local AI demo just dropped.
Quick Hits
- Authors push back on the Anthropic $1.5B settlement payout structure. TechCrunch reports that some named authors object to publishers (including HarperCollins) seeking 100% or 50% of payments on works, and to literary agents seeking a cut despite not being rights holders. Final approval landed in July 2026; per-work payments are $3,000 across roughly 500,000 titles, with in-print traditional titles split 50/50 author/publisher and self-published or reverted titles going 100% to the author. Reversion must predate August 10, 2022.
- Seattle Times and Newsday sue OpenAI and Microsoft. TechCrunch reports two more regional U.S. dailies joined the copyright-infringement wave, with the suit warning that AI could leave journalism “broken beyond repair.” Microsoft told GeekWire it was “surprised by the lawsuit” but open to “explore solutions.”
- Samsung unveils zHBM at FMS 2026. The Elec reports Samsung showed its z-axis High Bandwidth Memory prototype on August 5, with the August 4 keynote. Samsung claims up to 8x the data-processing performance of HBM5, 3x performance per watt, and more than 50% thermal resistance reduction. The same event showed zNAND-O (4-layer and 8-layer 3D-packaged on-device NAND) and V10 BV-NAND with 400+ layers.
- Hikers rescued on Mount Shasta after following Gemini’s trip plan. TechCrunch reports (citing a Chicago Tribune piece from September 3) that three hikers started a 3 a.m. ascent, reached the summit at 7 p.m., called the sheriff for directions after dark, and were rescued the next morning by Forest Service rangers. The Siskiyou County Sheriff’s office said Gemini advised them to bring “far less food and water than their group required.” The office’s advisory: “never rely solely on AI for your trip planning.”
- Artist Simon Weckert’s “digital camouflage” shirt beats a Berlin police AI camera. 404 Media reports the button-down shirt, with “flowery, blurry globs of green and pink,” makes the camera’s PERSON detection box disappear. Weckert developed it after Berlin police deployed AI object-recognition outside Kotbusser Tor station, the city’s first police-run AI surveillance system, which detects people, vehicles, animals, bicycles, and behaviors such as lying down, loitering, fighting, or abandoned packages.
- 404 Media podcast: a former Amazon warehouse worker on destroying books for AI. 404 Media spoke with a former worker at the Amazon warehouse that destroys books to train Amazon’s AI products. The September 2 episode is part of Emanuel and Sam’s reporting on the physical labor behind training-data pipelines.
- Bruce Blakeman posts AI-generated Mamdani/Hochul video; NY Democrats file a complaint. 404 Media reports the New York State Democratic Party asked the Board of Elections to investigate the September 1 post, which imagines Mayor Zohran Mamdani and Governor Kathy Hochul gardening, biking, and “vaguely colluding about making the state unaffordable.” Blakeman invoked the law’s “satire or parody” carve-out.
- OpenAI’s “research acceleration” thesis: RSI is the AGI path. Simon Willison’s writeup of an internal OpenAI post frames Recursive Self-Improvement as OpenAI’s operational AGI bet and is accompanied by a companion essay (“An Alien Mind”) from chief scientist Jakub Pachocki. A chart Willison reproduces shows median daily coding-agent spend per OpenAI researcher climbing from roughly $0-25 in February 2026 to about $50 in April, around $150 by June, a $150-165 July plateau, and a sharp climb to roughly $600 by late August; Willison argues the late-July inflection likely reflects internal employee access to the model later released as GPT-6 Astra.
Worth Watching
- Whether OpenAI names a third-party pre-release evaluator for GPT-6 Astra. Neither the launch announcement nor Simon Willison’s coverage discloses external safety testing, even as the recurrent-depth technique flagged two days earlier raised monitorability concerns. The natural test is whether METR, Apollo, or another independent evaluator publishes pre-release numbers before any safety case is filed.
- How the Stanford AI Index 2026 numbers hold up under close reading. The Index is the year’s most-cited reference work, and the headline gap-closure (Anthropic leading Chinese models by 2.7%) is sure to attract scrutiny; we will be checking the underlying benchmarks and the open-weight development section for what carries over to a local-AI analysis piece.
- Whether the bipartisan Flock backlash produces federal rules. Cato’s Patrick Eddington calls the data collection “absolutely constitutionally problematic” absent a criminal predicate, Rep. Massie’s bill would strip federal funds from using jurisdictions, and California SB 1013 would mandate training, audits, and search logs. The interesting test is whether any of these move before the midterms or whether the opposition stays at the rhetorical stage.
- Whether browser-side inference starts to show up in production apps. Hugging Face’s 207 WebGPU kernels and the existing WebLLM ecosystem put the runtime cost under 10x of a server-side small model; the next signal is whether a major product ships a client-side AI feature on this stack instead of paying for hosted inference.
- Whether the next AI-training copyright case uses the US government’s September 2 amicus brief as ammunition. The brief in the NYT case is a position statement, not a ruling, but it will be cited in every pending AI-training suit; the test is how Concord v. Anthropic and the new Seattle Times / Newsday complaint respond.
- Whether the OpenAI “wiki incident” triggers a public framework on agent disclosure. OpenAI says it is “working on a framework” with regulators for disclosing similar incidents, with details “in upcoming weeks.” The natural test is whether that framework covers the disclosure delay itself, not only the technical mitigation.
