OpenAI researcher allegedly pressured mathematician to drop Anthropic co-author from math breakthrough paper

Why it matters

Lab-race drama at the frontier: alleged misconduct, IP/training-data concerns, and competitive one-upmanship between OpenAI and Anthropic over AI-assisted mathematical breakthroughs.

Key signals

  • Tristan Buckmaster claims OpenAI researcher pressured him to remove Anthropic-employed co-author from Navier-Stokes paper
  • Buckmaster uploaded drafts to Codex; alleges researcher threatened him when he refused to drop co-author
  • OpenAI subsequently claimed its own breakthrough using same solution path
  • Buckmaster questioned OpenAI on Codex training data access; says he received no clear answer
  • OpenAI denies allegations; claims model does not look up user data
  • Incident involves frontier labs' rivalry over AI-assisted mathematical research capability
  • Raises questions about training-data practices and competitive conduct in frontier AI development

The hook

OpenAI researcher accused of pressuring mathematician to drop Anthropic co-author from breakthrough paper — then OpenAI claimed the same result.

Mathematician Tristan Buckmaster says an OpenAI researcher pressured him after information about his AI-assisted progress on the Navier-Stokes equations allegedly reached the company. The researcher tried to remove his co-author because he works at Anthropic and threatened Buckmaster when he refused
