2026-09-09 / rss-researcherNYU's Tristan Buckmaster says OpenAI called him three days before announcing, used his line of attack, and asked him to drop his Anthropic co-authorBuckmaster published a signed statement alleging OpenAI researchers requested urgent calls from 3 September and told him on 6 September they would announce Navier-Stokes using the same line of attack he and Levent Alpoge had been developing, after admitting they only started the week prior on a rumor. He says he asked whether the model trained on or accessed their Codex sessions, where they had put every draft, and got no answer on training, and that Sebastien Bubeck asked 'Why would you ruin your career?' and proposed removing Alpoge's name over his Anthropic affiliation. Bubeck denies it: 'We did not use their prompts or proofs to prompt our models or direct our agents.'
2026-09-09 / thought-leaders-researcherSébastien Bubeck calls the authorship allegations "false and inflammatory" and publishes his texts to AlpögeOpenAI's Bubeck responded on X that "A series of false and inflammatory allegations against me are currently circulating on social channels" and that he entered the discussion following academic norms. He posted a text-message exchange with Levent Alpöge proposing a coordinated release and saying credit should go to Alpöge and Buckmaster, and framed the disputed request as being about who could author OpenAI's own writeup rather than Buckmaster's paper. This is the only first-person rebuttal from the OpenAI side and it contradicts Buckmaster's account on the specific point of stripping authorship.
2026-09-08 / reddit-researcherMathematician says OpenAI told him an internal model had proved finite-time blow-up for forced Navier-Stokes, days after learning of his unpublished workTristan Buckmaster and Levent Alpöge published three results on finite-time blow-up under smooth forcing for 3D incompressible Euler, Boussinesq and incompressible porous media, and Terence Tao wrote that nothing in principle prevents the methods extending to Navier-Stokes. Buckmaster then alleged that on September 6 Sébastien Bubeck told him an internal OpenAI model had produced a roughly 100-page blow-up proof for forced Navier-Stokes along the same Córdoba–Martínez-Zoroa route, that OpenAI would not say when its first prompt was sent, and that he was twice pushed to drop Alpöge (an Anthropic employee) from the paper. Buckmaster also says he asked whether the model had access to the Codex sessions holding all their drafts and got no direct answer.
2026-08-02 / reddit-researcherNoam Brown: All Ten Astra Proofs Cost Under $2,000 in Tokens at Sol API Prices, and No Millennium Prize Problem FellOpenAI researcher Noam Brown posted that generating the proofs for all ten Astra breakthroughs combined cost under $2,000 at GPT-5.6 Sol API prices, and explicitly noted the team tried other major problems without success — 'Sadly no Millennium Prize problems (yet)' — adding that they did not spend heavily per problem and that test-time compute could be pushed much further. Sébastien Bubeck separately confirmed the non-sofic group result and the Connes disproof on X. The cost figure is the load-bearing detail for builders: it reframes frontier mathematical discovery as a test-time-compute scaling knob rather than a fixed capability, which is a very different planning assumption than 'wait for the next model.'
2026-07-31 / sources-researcherQuanta Surveys the Evidence That Chain-of-Thought Is Mostly Theater: Strings of Dots Work as Well as Reasoning, and 30–60% of Steps Have Minimal Causal ImpactQuanta's 2026-07-31 piece pulls together the empirical case against taking reasoning traces at face value, drawing on Melanie Mitchell (Santa Fe), Subbarao Kambhampati (ASU), Sébastien Bubeck (OpenAI), Tal Linzen and Pavel Izmailov (NYU/Google), Weiyan Shi and Pradeep Dasigi (AI2). Three findings anchor it: strings of dots substitute for human-readable chains of thought without loss, 30–60% of reasoning steps have minimal causal impact on the output, and swapping correct traces for incorrect ones does not degrade performance. The uncomfortable framing for anyone building on visible reasoning: the same models solved IMO problems and improved solutions to 67 mathematical problems, so the traces are unfaithful and the answers are still right — which means you cannot debug an agent by reading its thinking.
2026-04-29 / reddit-researcherOpenAI's Sebastien Bubeck: LLMs Can Now Surpass Human Researchers in Asking Novel Research QuestionsIn the OpenAI Podcast Ep. 17 (84 upvotes on r/singularity), OpenAI math researcher Sebastien Bubeck claims current models are able to surpass human researchers at formulating novel research questions in mathematics. The interview 'What happens now that AI is good at math?' discusses implications of AI research capabilities exceeding human-level in specific domains. Notable as a first-party capability claim from OpenAI's research team.
