OpenAI researcher allegedly pressured mathematician to drop Anthropic co-author from math breakthrough paper
Mathematician Tristan Buckmaster alleges OpenAI researcher Sébastien Bubeck pressured him to remove co-author Levent Alpöge (an Anthropic employee) from their Navier-Stokes breakthrough paper, allegedly asking "Why would you ruin your career?" OpenAI claims it independently produced a ~100-page Lean-formalized proof using ~10,000 coordinated AI agents in 88 hours with an internal model "significantly more capable than GPT-6 Astra," at a cost of millions in compute OpenAI denies seeing any of Buc
Analysis
TL;DR
- Mathematician Tristan Buckmaster alleges OpenAI researcher Sébastien Bubeck pressured him to remove co-author Levent Alpöge (an Anthropic employee) from their Navier-Stokes breakthrough paper, allegedly asking "Why would you ruin your career?"
- OpenAI claims it independently produced a ~100-page Lean-formalized proof using ~10,000 coordinated AI agents in 88 hours with an internal model "significantly more capable than GPT-6 Astra," at a cost of millions in compute
- OpenAI denies seeing any of Buckmaster and Alpöge's work before public release but acknowledges de-identified training data from their Codex usage may have improved its models
- Buckmaster and Alpöge's work addressed the forced Euler problem variant, while OpenAI claims its solution targets a different problem (unforced Navier-Stokes), suggesting the two efforts may not be directly competing
- OpenAI developer Noam Brown highlighted the dramatic cost reduction in AI math capabilities—from $500,000 for o3's ARC-AGI performance to ~$20 for Astra—predicting universal access to high-caliber math-solving AI within a year
Why It Matters
This incident sits at the intersection of AI-assisted mathematical research, corporate competition, and research ethics, raising critical questions about data usage boundaries when customers are also potential competitors. The allegations touch on whether AI companies should leverage user-generated content from their platforms to compete against those same users in high-stakes scientific discovery, a concern that will only intensify as AI capabilities in formal reasoning and theorem proving accelerate.
Technical Details
- Buckmaster and Alpöge used multiple AI models including Anthropic's Claude and OpenAI's Codex (GPT-5.6 Sol) over months, uploading all drafts to Codex throughout the project, achieving breakthroughs on Navier-Stokes-related problems by mid-August 2026
- OpenAI's solution was produced by approximately 10,000 coordinated AI agents working for 88 hours, generating a ~100-page proof formalized in Lean, using an internal model described as significantly surpassing GPT-6 Astra in mathematical capability
- OpenAI began training its new advanced math model on August 28 and pivoted resources toward Navier-Stokes after hearing rumors; the proof was completed and Lean-verified by September 6
- The internal model reportedly solves nearly three times as many open math problems as GPT-6 Astra, with the performance gap widening as compute scales up
- Cost trajectory: OpenAI's o3 model cost ~$500,000 to achieve 87.5% on ARC-AGI; the newer Astra model delivers superior performance for approximately $20, democratizing access to elite-level mathematical reasoning
Industry Insight
- AI companies must establish transparent data usage policies and opt-out mechanisms for high-value research users, as the default training data consent model creates ethical conflicts when user work on platforms competes with company-produced results
- The convergence of AI theorem proving and open mathematical problems signals an impending shift in how mathematical research is conducted, with compute-accessible AI agents becoming co-authors rather than mere tools—requiring new norms around authorship, priority, and collaboration
- The incident highlights the strategic risk of "scooping" dynamics in AI research: as model capabilities democratize rapidly (from $500K to $20 compute), the window between discovery and competitive replication shrinks, potentially incentivizing aggressive data practices that could erode trust in the AI research ecosystem
