Claim

The researchers behind the Euler blowup result wrote a letter saying OpenAI offered them credit and lead authorship on the Navier-Stokes paper on condition that their Anthropic co-author be dropped.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

Buckmaster's public statement says Bubeck twice asserted he wanted Alpöge removed from authorship.

From Statement Read 2026-09-20 Relevance STRONG Steps 1 Counted

Primary document from Tristan Buckmaster of NYU Courant, so the substance holds. Three corrections to the claim's framing: it is a public statement PDF, not a letter addressed to anyone; the lead-authorship offer concerned a paper presenting the NAVIER-STOKES result, not the researchers' own Euler blowup paper, which the claim conflates; and the stated reason was that Alpöge works at Anthropic, with the document not using the phrase "conflict of interest". This is one side of a contested account — Bubeck denies it.
The excerpt says OpenAI offered priority and credit on the Navier-Stokes solution, including lead authorship, if the person dropped their Anthropic coauthor.

Qualifications

Mostaque says Bubeck has posted an account that reads as a misunderstanding.

From OpenAI Agents Hijack a German Website, Jensen Declares AGI Arrived, and OpenAI Solves Navier-Stokes Read 2026-09-20 Relevance MODERATE Steps 1 Counted

The OpenAI lead's own posted account reframes the same exchange as a misunderstanding rather than a condition placed on authorship.

Suppressed as dependent

None.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
