OpenAI Accused of Scooping Navier-Stokes Work; Bubeck Denies Allegations

The controversy stems from a dispute between OpenAI and independent researchers including Tristan over attribution of Navier-Stokes equation solving research: reports claim OpenAI may have accessed private Codex session data from Tristan and Levent, based on OpenAI's refusal to confirm it did not train on that data.

Confirmed

• The core allegation, relayed by @Jsevillamol, is that OpenAI declined to confirm it did not use the two mathematicians' private Codex sessions for training, which was read as possible access to that data.
• OpenAI researcher willdepue publicly responded that such snooping could not happen, saying OpenAI, like other large regulated platforms, has strict controls on user data access.

Unconfirmed

• Whether OpenAI actually accessed or used private Codex session data remains an indirect inference (a refusal to deny), with no direct evidence.
• @generatormanai noted community debate over research priority: one side argues Tristan sharing his work with OpenAI steered the model toward that research direction, unlike parallel discovery; the other side points out there is no evidence Tristan ever made such a share.

Why it matters

• @basedjensen, from an industry insider's perspective, argues that "training on private Codex sessions" would require bypassing multiple layers of internal security controls—unlikely unless ordered at the institutional level—and doubts OpenAI leadership would take on that liability risk. This provides a framework for evaluating the rumor but leaves open the possibility of institutional action.
• @teortaxesTex flagged a deeper concern: if OpenAI can freely read users' Navier-Stokes sessions, it implies routine scanning of user sessions to "snipe" valuable results—shaking the very foundation of user trust in tools like Codex.
