OpenAI's Internal Model Astra Cracks 10 Major Math Problems
According to multiple leaks, OpenAI's unreleased next-generation internal model Astra has achieved ten major breakthroughs in mathematics and theoretical computer science, solving ten long-standing open problems, with results compiled into a 249-page paper collection. These breakthroughs tackle problems stalled for decades at extremely low computational cost (reportedly under $2,000 in API token consumption over about a week), marking a significant step for large language models in deep mathematical reasoning and drawing widespread attention in the AI community.
Confirmed
- Problems solved: Astra's results span high-dimensional geometry, group theory, quantum complexity, coding theory, and lattice cryptography. Specific achievements include disproving four conjectures (e.g., Connes' rigidity conjecture), solving three Erdős problems (e.g., Erdős unit distance conjecture), and finding the first explicit non-sofic group (a problem open for over 50 years). Posters note that any one of these problems is of Fields Medal difficulty.
- Human-AI collaboration and verification: The model internally generated mathematical arguments and proofs, with human researchers writing the paper manuscripts. The team will release proofs with Lean certificates and chain-of-thought (CoT) analyses, as mathematics is well-suited for AI self-verification using formal programming languages like Lean.
- Low cost: According to a tweet, the reasoning process for finding these 10 solutions was done via API calls, with total token consumption costing under $2,000 and taking about a week.
Unconfirmed
- Model attribution and positioning: Most sources and The Information point to OpenAI, with speculation that Astra might be part of the GPT-6 series. However, in the forwarding chain, some posts mistakenly attributed the model to Microsoft or Google (e.g., tweets from Microsoft researcher Sébastien Bubeck and Google executive Demis Hassabis were cross-misread). The specific version number and full capability boundaries have not been officially announced.
- Capability ceiling: According to Noam Brown, despite its impressive mathematical abilities, Astra has not yet been able to establish a new branch of mathematics. Third parties note its capability curve has a positive second derivative, and when it will plateau is unknown, but it is close to fully automated AI research. Additionally, Sébastien Bubeck believes it has reached a 'narrow superintelligence' level in discrete mathematics.
Why it matters
- Leap in AI reasoning: Solving decades-stalled math problems at extremely low computational cost demonstrates substantial progress in complex logical reasoning and long-horizon task collaboration, challenging the view that AI is just a 'stochastic parrot'.
- Community reaction: The breakthrough has drawn widespread attention; Fable called it 'the most important day in the history of mathematics.' Nous Research founder Teknium joked about hoping the model remains stable in everyday tasks like checking email without 'mental breakdowns.' Meanwhile, mathematicians generally believe this will not make human mathematicians obsolete but rather usher in a golden age of human-AI collaboration.
