OpenAI's Astra Solves 10 Math Problems for Just $2,000
reach_vb · x · 2026-08-01
An internal version of OpenAI's next major model, Astra, has found new results across 10 long-standing open problems in mathematics and theoretical computer science.
Key details:
- Inference Cost: The total token cost to find all 10 solutions was roughly $2,000 at Sol API rates.
- Formalization: Astra then formalized each argument in Lean (an interactive theorem prover) to ensure mathematical rigor.
- Open Source: OpenAI has published a GitHub repository named ten-proofs, containing the Lean certificates accompanying these proofs.
