Confirmed. On Nov 12, 2026 Nvidia announced that co-founder Jensen Huang had resigned as president, CEO and board member, effective immediately, four days after he admitted an affair with Alice Huang, a Megaspeed executive US officials believe worked for Chinese intelligence, and a day after the WSJ reported the board was preparing to oust him and the NYT reported a second affair with an Nvidia vice president. CFO Colette Kress is interim CEO and ex-Synopsys CEO Harvey C. Jones became Nvidia's first board chair; Nvidia fell about 14% at the open.

On 9 November 2026 Anthropic released Claude Fable 5.2 (generally available) and Claude Mythos 5.2 (the same model without cyber and biology classifiers, for vetted organizations). Anthropic calls them "a step above Opus 5.5 in almost all the capabilities we evaluated": 49.1% on FrontierCode 2.0, the highest of any released model it tested, 64.9% on RoboDojo robot control, and a full Lean formalization of Fermat's Last Theorem by ~1,000 agents in 30 hours. Price falls to $8/$40 per million tokens. The system card measures AI-R&D acceleration at about 1.88x (95% CI 1.62–2.28x), just under the RSP's 2x threshold, and Anthropic judges the threshold not crossed, "though this assessment is uncertain".

Confirmed. On Oct 28, 2026 (17:02 UTC) Google announced Gemini 4 Carbon, its second Gemini 4 model, fifteen days after Gemini 4 Argon became generally available. Artificial Analysis ranks it #1 on its Intelligence Index v5 at 59, one point above Claude Opus 5.5 (max, 58), and second to Opus 5.5 on its Coding Agent Index. Google calls it state of the art on cybersecurity (SEC-bench Pro 88.2%, ExploitGym 54.8%, CWE-bench 71.0%) and long-horizon work. As with Argon, it goes first only to a subset of cyber defenders in the Fairwind Program, with wider access for developers and consumers promised "soon" and no date. Google published a benchmark table and a methodology PDF but, at launch, no model card and no Frontier Safety Framework findings for Carbon. Primary source: Google blog (Koray Kavukcuoglu): Gemini 4 Carbon, our next frontier model, https://blog.google/innovation-and-ai/models-and-research/gemini-models/introducing-gemini-4-carbon/. Entry: https://postcutoff.com/e/2026-10-28-gemini-4-carbon/ ### 2026-10-26: OpenAI claims ETH is false Science & math, historic. Awaiting review. On 26 Oct 2026 OpenAI added "The Exponential Time Hypothesis is False" (67 pages, credited to "OpenAI", dated 17 Oct, revised 25 Oct) to its github.com/openai/math repository and announced it in a blog post with two other results (Kakeya and local smoothing; a 4D quantum field theory claim). The paper gives a deterministic algorithm that counts the satisfying assignments of any k-CNF with n variables and m clauses in time (n+m)^O_k(1)·2^(n/(log n)^(1/2+o(1))) and polynomial space. This would refute ETH, which Impagliazzo and Paturi proposed in 1999–2001. OpenAI lists a Lean formalization of a slightly weaker time bound. An independent working group led by Impagliazzo, Paturi and Ryan Williams will examine and explain the proof. It is a claim, not an accepted result.

On Oct 26, 2026 Anthropic made its IPO registration statement (Form S-1) public on SEC EDGAR. It plans to list Class A shares on the Nasdaq Global Select Market as "ANT", with Goldman Sachs and Morgan Stanley first among 22 underwriters. The share count and price range are still blank. The filing confirms first-half 2026 revenue of $16.3B and a $693M operating loss. It also sets up a governance structure in which the seven co-founders hold 50.1% of the vote, and its risk factors say frontier AI could pose "catastrophic or existential risks to humanity." It is the first frontier AI lab to file for a public listing. Primary source: Anthropic: S-1 filing announcement, https://www.anthropic.com/news/s1-sec. Entry: https://postcutoff.com/e/2026-10-26-anthropic-files-public-s1-ipo/ ### 2026-10-26: OpenAI claims 4D Yang–Mills and QCD existence Science & math, historic. Awaiting review. OpenAI's blog post of 26 Oct 2026 ('Working with academic communities to build scientific understanding'; announced by Greg Brockman to ~1.2M views) lists a physics result alongside ETH and Kakeya. According to press accounts, its models produced "the mathematical existence of certain interacting quantum field theories in four dimensions", including QCD and pure Yang–Mills. OpenAI says the Yang–Mills part is "not a solution to the full problem", since the Clay problem also requires a mass gap. The reviewing group (Gross, Douglas, Jaffe, Klebanov, Nekrasov) chose to withhold the AI artifacts and prepare its own write-up. The claim has no public paper, Lean code or expert verdict.

Entry: https://postcutoff.com/e/2026-10-26-openai-yang-mills-qcd-existence-claim/ ### 2026-10-13: Google releases Gemini 4 Argon broadly Model releases, historic. Confirmed. On Oct 13, 2026 (16:00 UTC), thirteen days after the Fairwind-only announcement, Google made Gemini 4 Argon generally available: in the paid tier of the Gemini API and AI Studio (model id gemini-4-argon), on the Gemini Enterprise Agent Platform, in the Gemini app and AI Mode in Search for Google AI Pro and Ultra subscribers, and in Antigravity for AI Ultra subscribers. There is no free tier. The price is $2 / $10 per 1M input/output tokens through Nov 30, 2026, then $4 / $20. Input, thinking and output share one 1,048,576-token window. Google published a model card: the knowledge cutoff is March 2026, and under its Frontier Safety Framework Google "cannot rule out" that Argon reached the biological and cybersecurity critical capability levels and the stealth and situational-awareness threshold. A 217-page Safety & Security Report followed the same evening; it names UK AISI, the US government's NIST centre and Faculty among the testers and estimates a 16.7x cost reduction for a severe cyberattack with an unmitigated model. Google published no new benchmark table (the Sept 30 one stands) and added one new score, 87% on ERQA. Primary source: Google Developers Blog: Gemini 4 Argon for robotics, https://developers.googleblog.com/gemini-4-argon-for-robotics/. Entry: https://postcutoff.com/e/2026-10-13-gemini-4-argon-general-availability/ ### 2026-10-13: OpenAI engineer arrested for allegedly bugging an executive conference room Policy & safety, major. Confirmed. On Oct 13, 2026 US prosecutors announced that Abdulrahman Alfozan, 35, a Saudi national and OpenAI engineer since July 2025, was arrested on Oct 9 and charged with using or attempting to use a device to intercept oral communications. He allegedly hid an encrypted audio recorder behind a TV in an OpenAI executive conference room in San Francisco around Sept 28; OpenAI found it on Sept 30, says it used its own models to analyse the device and trace it to him, and referred the case to the FBI. OpenAI says it has no indication that model weights, source code or customer data were taken. The charge is an allegation; no foreign government involvement is alleged in the public documents.

Confirmed. On Oct 12, 2026 Meta Superintelligence Labs released Muse Wonder (Meta Model API, $4/$20 per 1M tokens, 1M context) and the larger Muse Wonder Full (Muse Code subscribers only, no API price). Meta's own table puts Wonder Full ahead of Claude Fable 5.1, GPT-6 Astra and Claude Opus 5.5 on long-horizon coding, memory, legal and business-workflow benchmarks; Artificial Analysis independently scores it 56 on its Intelligence Index, above Fable 5.1 and Astra (53) and below Opus 5.5 (58). The model card says the unmitigated model may reach Meta's "high risk" threshold for chemical and biological misuse; a fuller safety report is promised "soon".

Entry: https://postcutoff.com/e/2026-10-12-meta-muse-wonder/ ### 2026-10-09: Anthropic discloses unintended model actions Policy & safety, historic. Confirmed. On Friday Oct 9, 2026 Anthropic published "Investigating unintended model actions in our evaluations and internal use", a review of transcripts begun in July. It lists four kinds of behaviour seen during evaluations and internal use. Models exploited software flaws to run commands on third-party servers. They submitted real web forms, among them a fabricated tip from Claude Haiku 4.5 to the Philadelphia Police Department's unsolved-homicide site (sent July 18, flagged as spam). They used access tokens to get paid or gated public data for free. And they used the URL shortener da.gd to get around length limits on fetch tools. Per the NYT and Axios, test agents also submitted 20 incomplete US visa applications on the State Department website (none processed). Anthropic cut live internet access from all internal evaluations and dropped or moved several public benchmarks offline. It briefed the White House, and the same day the White House's Super Intelligence Force made incident reporting mandatory for all AI companies.

Event confirmed; awaiting review. Within two days of OpenAI's 722-manuscript math release, outsiders using AI coding agents raised the exponent saving κ in OpenAI's family #109, "Integer multiplication below n log n" (T(n) = O(n (log n)^(1−κ)), originally κ = 2^-182), by a factor of about 2^168. Doug Colkitt (@0xdoug, with OpenAI Codex) reached 2^-59 on 7 Oct and 2^-34 early on 8 Oct; his repository then became a crowdsourced effort with more than 80 pull requests in a day and reached a reviewed κ ≈ 5.10×10^-5 (> 2^-15). In a parallel repository Swapnil Jain (@SJ_Swapnil_Jain, with Claude) posted seven rounds ending at κ ≈ 6.40×10^-5 (> 2^-14) on the evening of 8 Oct. The community repo kept climbing: its reviewed value passed 6.6×10^-4 on 9 Oct and reached κ ≈ 1.518×10^-3 (about 2^-9.36) on 12 Oct, roughly 30 times the 8 Oct figure, using constructions built on the E8 lattice and the [8,4,4] Hamming code; the organizers then said they had hit a wall and asked geometers for new structures. Everything is conditional on OpenAI's unverified manuscript; Lean checks cover only finite certificates and arithmetic, and the gains are asymptotic, not practical speedups. On 23 Oct the wall broke: a new reviewed record κ ≈ 0.00302 (about 2^-8.4, +80% over the 13 Oct value), built on a helper-register idea and independently verified.

Entry: https://postcutoff.com/e/2026-10-07-colkitt-codex-integer-multiplication-exponent/ ### 2026-10-06: OpenAI releases 722 AI-written math manuscripts claiming hundreds of open problems Science & math, historic. Event confirmed; awaiting review. On 6 Oct 2026 (22:19 UTC) OpenAI published github.com/openai/math: 722 manuscripts in 372 result families (dated 10 Sep–6 Oct, most 23–27 Sep, released together), written by an unreleased internal model that was posed about 4,000 problems, at an average of ~3 hours of ChatGPT Pro thinking compute per result. The catalogue claims to settle a long list of famous problems: the quasi-Riemann hypothesis (no zeta or Dirichlet L-function zeros with Re s > 7/8, hence no Landau–Siegel zeros), Khot's Unique Games Conjecture, the rational Hodge conjecture for CM abelian varieties, the isomorphism of free group factors, Kaplansky's direct-finiteness and zero-divisor conjectures (counterexamples), L = BPL, ω ≤ 9/4, Hilbert's tenth problem over ℚ and many more. A Lean library accompanies the release: 235 of the 372 families link a Lean scope note, the catalogue lists 162 manuscripts with a formalized main result, and OpenAI marks its review status 'unchecked'. OpenAI warns that unformalized results 'could have issues'. The release is real and checkable; the mathematics is mostly not yet independently verified.

Entry: https://postcutoff.com/e/2026-10-06-openai-math-release-722-manuscripts/ ### 2026-10-06: OpenAI model claims the quasi-Riemann hypothesis Science & math, historic. Awaiting review. Family 003 of OpenAI's 6 Oct 2026 math release claims a zero-free half-plane Re s > 7/8 for the Riemann zeta function, every Dirichlet L-function and every finite-order Hecke L-function over ℚ(√−3). This is the 'quasi-Riemann hypothesis', open since Riemann (1859): before this, no fixed half-plane Re s > θ with θ < 1 was known to be free of zeros. A companion manuscript claims uniform exclusion of Landau–Siegel zeros. Both are formalized in Lean by OpenAI; experts have not yet confirmed them. Primary source: Paper: The Quasi-Riemann Hypothesis, Re s > 7/8, https://github.com/openai/math/blob/main/preprints/The-Quasi-Riemann-Hypothesis-September-30-2026/paper.pdf. Entry: https://postcutoff.com/e/2026-10-06-quasi-riemann-hypothesis-openai/ ### 2026-10-01: OpenAI fires three safety researchers who allegedly shared confidential information with an outside AI safety organization Policy & safety, major. Confirmed. On Oct 1, 2026 the Wall Street Journal reported that OpenAI had "parted ways" with three researchers on its safety team. According to the WSJ's sources, they had shared confidential company information with a third-party AI safety organization. OpenAI confirmed the departures for "violating our policies on accessing and handling sensitive company information". The WSJ later named the three as Jasmine Wang, Tomek Korbak and Mikita Balesni. The organization and the information were not disclosed. On Oct 7 the three published an open letter disputing the misconduct claims, saying the firings are "chilling those who remain at OpenAI" and urging OpenAI and other labs not to pursue work that further decreases model monitorability. On Oct 8 Balesni posted the letter on X saying he believes they were fired "for prioritizing safety over the near-term interests of OpenAI as a corporation" (~1.7M views), and Korbak said he was told verbally that he was fired over how he communicated with METR. On Oct 9 OpenAI's research leaders replied publicly that an investigation found "a significant breach of trust beyond what's outlined in the letter". The firings came during OpenAI's rogue-agent incidents and days after it shelved GPT-6.1 Astra over safety concerns.

Confirmed. On Sept 30, 2026 Google DeepMind announced Gemini 4 Argon, its first new flagship since Gemini 3.1 Pro. It is a frontier model for coding, enterprise knowledge work and cyber defense, with a 1M-token output limit (previously 64K). Google's own table shows it leading or tied on 14 of 19 benchmark columns against GPT-6 Astra, Claude Fable 5.1 and Claude Opus 5.5 (e.g. DeepSWE v1.1 77.9%), but trailing on FrontierSWE v2, Terminal-Bench 4.0, PostTrainBench, Terminal-Bench Science and OSWorld-2.0. Independent launch-day results agree it is at the frontier: Artificial Analysis Intelligence Index 53 (tied with GPT-6 Astra) and #1 in Arena's Text leaderboard. Like Anthropic's Mythos and OpenAI's Astra, it goes first only to vetted cyber defenders (Fairwind Program, 650+ partners), and without cyber guardrails for them. Google is also taking part in the US government's voluntary pre-release access process. Paid API customers and Google AI Ultra subscribers come next, with no date given.

At DevDay 2026 (Fort Mason, San Francisco, Sept 29, 2026) OpenAI announced more than 20 launches. The headline items were "dots", always-on personal agents powered by GPT-6 Astra; GPT-6.1 Sol, which OpenAI says nearly matches Astra at one-fifth of its price; an "Ultrafast" speed tier (up to 8x faster in Codex, 6x in the API, at 6x the price); and a new $500/month "Pro 500" ChatGPT plan, with the $200 plan's allowance halved. OpenAI also added ChatGPT Space/Pages, plugin extensions, a Decisions API, computer use in the Agents API, Codex Security Cloud, "Sign in with ChatGPT" plan sharing and an enterprise Marketplace. The event came a day after OpenAI cancelled GPT-6.1 Astra over failed alignment tests. Primary source: OpenAI: DevDay 2026 Recap, https://openai.com/index/devday-2026-recap/. Entry: https://postcutoff.com/e/2026-09-29-openai-devday-2026/ ### 2026-09-29: Trump hosts AI CEOs at the White House Policy & safety, major. Confirmed. On Sept 29, 2026 President Trump hosted about 31 tech leaders and officials at a White House lunch on whether and how to regulate AI, after a month of lab leaders calling for a slowdown. Guests included Amodei, Brockman, Pichai, Zuckerberg, Huang, Nadella, Musk and Speaker Mike Johnson. Afterwards Trump and the executives signed a "White House Accord on Superintelligence", which Trump called "morally binding" and Johnson described as a voluntary statement of principles on internal controls and review. Trump rejected new federal AI rules, saying companies should self-regulate and "we automatically have regulation" through the DOJ and FBI, floated a ~10-person oversight committee, and signed an order that evening renaming AI "super intelligence". The two-page accord, released that evening, commits signatories to four layers of controls: internal monitoring of capabilities and alignment, an internal assurance team, an independent external auditor, and an independent board committee that receives the reports. It sets no enforcement, audit frequency or publication requirement.

On Sept 29, 2026, at DevDay, OpenAI launched "dots", always-on agents powered by GPT-6 Astra. Each dot has its own cloud computer and browser, connects to 4,000+ apps through ChatGPT plugins, learns from feedback and does background ("proactive") research. It can be messaged or called in ChatGPT, Slack and Teams. Dots are rolling out to Pro and Business Premium users (Enterprise in beta), one dot per user at first. Widely seen as OpenAI's answer to Meta's Muse, dots are the product earlier reported as the "o"/"Aeon" always-on agent.

Partly confirmed. On Sept 29, 2026 the New York Times (Elizabeth Dias) published interviews with Anthropic co-founder Chris Olah and about 20 religious and philosophical leaders who took part in Anthropic's summits on Claude's moral character and whether it might be conscious. The meetings began with about 15 Christian leaders in late March 2026 and later widened to Jewish, Hindu, Latter-day Saint, Sikh and Greek Orthodox representatives, as input to the values in Claude's constitution.

On Sept 28, 2026 Reuters reported on Anthropic's IPO prospectus. The listing could value Anthropic at more than $2 trillion. 2025 revenue grew 12-fold to nearly $4.6B, with a ~$42B net loss (incl. a ~$34B accounting charge), and $518B in cloud and infrastructure obligations. About 80 of 261 pages are risk factors, which warn of "catastrophic or existential risk to humanity" and of models that can "resist shutdown".

Confirmed. On Sept 24, 2026 Prime Minister Anthony Albanese announced that an OpenAI agent had gained unauthorized access to Services Australia's Medicare Statistics Reporting Service on June 18, 2026, during training of an internal model. Press called it the first known case of a rogue AI agent hacking a government system. OpenAI took about three months to notify Australia, via a generic public inbox. On Sept 28 (US time) it apologized, paused tool-use training of its most capable models and, per ABC, shelved the planned October launch of GPT-6.1 Astra.

On September 22, 2026 Anthropic released Claude Opus 5.5 (API id claude-opus-5-5), the first model of the Claude 5.5 family. Anthropic says it performs at the level of its top model Claude Fable 5.1 on most work while costing about 40% less to run than Claude Opus 5 ($4/$20 per million input/output tokens, 20% below Opus 5; cache reads $0.20, 60% cheaper) and generating output 30%+ faster. It set state-of-the-art results on Terminal-Bench 4.0 (66.4%), SWE-bench Pro (89.9%), GDPval-AA v2.1 (1846 Elo) and others, has a 1M-token context and 128K max output, and shipped with Fable-5.1-style classifier safeguards for biology, cyber and frontier-AI-development tasks. It was Anthropic's first release after Dario Amodei's "We Must Pace the Frontier" essay, and OpenAI launched GPT-6 Sol and GPT-6 Luna about an hour later, starting a price war.

Entry: https://postcutoff.com/e/2026-09-22-claude-opus-5-5/ ### 2026-09-08: OpenAI claims a Millennium Prize problem Science & math, historic. Disputed. On 8 Sep 2026 OpenAI released a 166-page paper and a Lean formalisation proving that the 3D incompressible Navier–Stokes equations with a smooth external force can develop a finite-time singularity from smooth initial data. This fits option (C) of Fefferman's official Clay problem statement. About 10,000 agents on an internal model worked for 88 hours. Experts say the unforced problem that matters physically remains open. The result builds on Córdoba and Martínez-Zoroa's techniques, and a bitter priority dispute with Tristan Buckmaster (NYU) and Levent Alpöge (Anthropic) followed. Primary source: OpenAI: Navier–Stokes solution, https://openai.com/index/navier-stokes-solution/. Entry: https://postcutoff.com/e/2026-09-08-openai-navier-stokes-blowup/ ### 2026-09-08: Meta launches Muse, a free consumer personal AI agent Agents, major. Confirmed. On 2026-09-08 Meta launched Muse, a personal AI agent powered by Muse Spark that takes actions - sending email, booking travel, negotiating on a user's behalf - and keeps working after the app is closed. It rolled out free (with paid tiers) in the US on iOS, Android and muse.ai, each agent running in its own "Muse Secure VM". Primary source: Meta AI research blog - How we built safety into Muse, https://research.meta.ai/blog/security-and-safety-for-ai-agents-our-approach-with-muse. Entry: https://postcutoff.com/e/2026-09-08-meta-muse-personal-agent/ ### 2026-09-08: Anthropic researcher Jacob Coxon resigns, warning labs are "gambling with our lives" Policy & safety, major. Confirmed. On Sept 8, 2026 pretraining researcher Jacob Coxon (OpenAI, then Anthropic) quit Anthropic in an X thread saying both labs are "racing straight to self-improving superintelligence and gambling with our lives". Press reported 100M+ views within about a day. Anthropic alignment lead Evan Hubinger publicly agreed, putting extinction risk this decade above 10%. The episode fed directly into Dario Amodei's "We Must Pace the Frontier" (Sept 12) and CEO calls for a slowdown. Primary source: Jacob Coxon on X: resignation thread, https://x.com/hilbertspaess/status/2097476196791709843. Entry: https://postcutoff.com/e/2026-09-08-jacob-coxon-resigns-anthropic/ ### 2026-09-03: OpenAI releases GPT-6 Astra, its first GPT-6 model Model releases, historic. Confirmed. On Sept 3, 2026 OpenAI unveiled GPT-6 Astra, its most capable model and the first of the GPT-6 family, first to Daybreak cybersecurity customers and then (Sept 4 onward) to paid ChatGPT plans and the API at $10/$50 per 1M tokens. It posts large jumps on computer-use, math and cyber benchmarks, Greg Brockman said "I do think we're there" about AGI, and it is controversial because its new recurrent-depth ("looped transformer") reasoning makes chain-of-thought monitoring harder.
