BREAKING: OpenAI might have stolen another major proof. In a detailed Mastodon post, which I report in full in the comments, Andreas Thom presents several pieces of evidence suggesting that OpenAI may have trained Astra on conversations in which he and Gábor Kun were working on Gromov’s soficity conjecture, one of the ten problems OpenAI later announced Astra had solved. I know Andreas. We met several times early in our careers. He is an exceptional mathematician, a leading expert on sofic and hyperlinear groups, and one of the most respected scholars in the field. He has spent two decades working on this problem. If his account is correct, this is not a minor dispute over attribution. It would mean that unpublished human work was absorbed into a model and then presented to the world as a breakthrough by the model itself. And if the allegations raised by Levent Alpöge, Tristan Buckmaster, and now Andreas Thom are all substantiated, we are no longer looking at isolated incidents. We may be looking at one of the greatest intellectual scandals in the history of science. AI is not discovering new mathematics. AI is stealing human discovery.

Sweet mother of God. @GaryMarcus
tristan buckmaster just published a statement that is, if accurate, one of the ugliest things i’ve read out of a frontier lab. not because of the math. because of what happened after openai found out two people were about to beat them to the punch. buckmaster and levent alpöge spent a year pushing the córdoba / martínez-zoroa program to smooth forcing. august 15 they got blowup for boussinesq and 3d euler. lean-verified august 22. they were paying openai out of pocket and dumping every draft into private codex sessions. the program is obscure. almost nobody else was on it. this was not “paste the clay problem into a chatbot.” then this: > thursday sept 3, buckmaster emails openai privately. rumors are flying. he is trying to stop a mess, not start one. > they reply the same day: give us details so we can “avoid competing.” also, want free compute? > sunday they suddenly need a call “at any point today.” sebastien bubeck gets on. levent is not invited. > openai says an internal model has a ~100-page proof of forced navier–stokes blowup. fefferman options c and d. the exact route buckmaster and alpöge had quietly chosen. > they show him a prompt and claim the model was “simply given the problem statement.” levent is told “very little human input.” > that falls apart on the same call. a whole team had been on it. they started on the unforced problem, warmed the model up on easier equations including euler, and even the prompt they showed him was written by prompting codex. > he asks when the first prompt went out. they stall. then agree: the past few days. after information about his work reached openai. > he asks whether the model was trained on, or had access to, the private codex sessions where they put every draft of this project. > answer: the model does not look up user data. > he asks again. about training. > no answer. then it stops being a science story and becomes an hr story. > offer 1: you post euler. we post navier–stokes the next day. > offer 2: after you post euler, you alone write the navier–stokes paper, credit our model, and we cut levent. > bubeck says twice he wants levent removed from authorship because he works at anthropic. he declines both. he says if they release it that way, he goes public. the reply is not a scientific objection. > “why would you ruin your career?” > “if you don’t want me to be nice, then i don’t have to be nice.” later, a text to levent proposing a one-on-one: > “i don’t know if tristan is being fully rational right now.” that is not how you treat a collaborator. that is how you split one. openai got word two researchers were closing a path almost nobody else was on. they spun up a team on that exact path. they would not answer whether the researchers’ unpublished drafts in openai’s product were used. they tried to dictate the announcement order. they tried to remove a coauthor because he works at a competitor. when that failed, someone reached for a career threat. this is a lab finding out academics were about to publish, sprinting the same narrow program, refusing the data question, and trying to manage credit around a rival affiliation. really slimy if even half of this holds. what the fuck is happening.

Pregunta a la comunidad vinculada a Iberia: sabe slguien de Don Emilio @alternateb747..? No se lo lee desde hace semanas (su ultimo post creo fue el 30 de junio). No se si @fjlopezm11 puede tener alguna pista. Ojala este todo bien, se lo extraña por estos lares.

It's always nice to see one's work cited by other academics. Marghoti et al. (2026) work proving that that standard 3-body Kuramoto couplings are mathematically equivalent to pairwise connections modulated by latent transmission channel variables. In arxiv.org/abs/2607.07662

Some of the answers to Frances' post, regardless of your stance and opinions about the whole saga and Arday's failings (who is ever exempt from them?) reveal how fucked up some people are. I am perhaps surprised, but I know I shouldn't.
What kind of person writes a rant like this about someone who has tragically died at the age of 41 leaving two small children? Show some respect, Julia. Shut up.

"We’ve spent four decades treating back-propagation as the only law of physics in neural networks." Law of physics 🤣 Clueless clown... Example of dressing up an interesting paper in distributed-systems engineering and mathematical optimization in cheap "AI bro" terminology.

Interesting post. Although the OP omits certain nuances e.g. - Systemic thresholds are designed so that the net income path stagnates rather than dip into negative territory; - Higher gross income means the couple is paying significantly more into the Rentenversicherung (pension fund) and unemployment benefits (it's an intertemporal allocation rather than a total loss, in principle); - There are also differences in the regional impact, as local housing costs (wohngeld) are linked to local rent levels; and - The loss of child supplement benefits (kinderzuschlag) does not eliminate the universal allowance child benefit allowance (kindergeld); the issue is nevertheless real: the current system actively discourages secondary earners (often women) from transitioning from part-time to full-time work. And it's also true that skilled workers frequently reject minor promotions because the extra stress and responsibility are rewarded with only a few euros a month, after benefits are stripped away. The German tax and social welfare state does not play in favor of low-to-middle-income families. That's a fact. But as ever, there are two conclusions to draw depending on the looking glass used: - To libertarians, this is a classic case showing that destroying market incentives has clear negative consequences. It's a "welfare trap": instead of helping German citizens achieve financial independence, the system makes staying in low-paying or part-time work the most logical economic choice, thus leaving people dependent on state structures. - From those on the side of social welfare, the issue stems from poor coordination and flawed system integration. In essence, they believe the core issue is in the "exit ramps" (how fast benefits are cut off when a worker earns more). That's the majority view at the IFO, despite the fact that it was Clemens Fuest (the IFO president) who illustrated the "welfare trap" scenario. Be that as it may, the consequences are seen in the severe shortage of skilled tradespeople, which I can vouch for (my father in law is facing this acutely). This is not an exclusive issue in Germany, mind you. @ocampo_emilio @constant_hevia @IvanWerning
Schau dir diese Grafik genau an. Sie erklärt, warum sich in Deutschland Leistung nicht mehr lohnt. Ein Paar, zwei Kinder, beide arbeiten. Bei 4.000 Euro brutto bleiben rund 2.700 Euro. Bei 5.000 Euro brutto bleiben rund 2.650 Euro. Du liest richtig. Tausend Euro mehr verdient. Weniger im Portemonnaie. Und jetzt der Teil, der wirklich weh tut: Bei 2.000 Euro brutto stehen dieser Familie etwa 2.350 Euro zur Verfügung. Bei 5.000 Euro brutto sind es 2.650 Euro. 3.000 Euro mehr erarbeiten. 300 Euro mehr haben. Das ist kein Rechenfehler. Jeder zusätzlich verdiente Euro zieht Wohngeld, Kinderzuschlag und Freibeträge mit sich in den Abgrund, während Steuern und Sozialabgaben gleichzeitig steigen. Man nennt es Transferentzugsrate. Ökonomen kennen das Problem seit Jahren. Die Bundesregierung hat Gutachten dazu bestellt. Passiert ist nichts. Und dann wundert sich die Politik, warum niemand mehr die Stunden aufstockt. Warum die Zweitverdienerin in Teilzeit bleibt. Warum der Facharbeiter die Beförderung ablehnt. Die Leute sind nicht faul. Sie rechnen. Ein System, das Anstrengung und Fleiß nicht belohnt, bekommt am Ende genau das: keine Anstrengung.
