Imagine an AI that not only solves complex math problems but also writes out the proofs in a language mathematicians can verify. That's the promise of DeepSeek-Prover, a new AI model that's pushing the boundaries of automated theorem proving. Formal mathematical proofs, the gold standard of mathematical certainty, are notoriously difficult and time-consuming, even for experts. DeepSeek-Prover tackles this challenge by training on a massive dataset of 8 million synthetic proofs, generated from high-school and undergraduate-level math competition problems. The process starts by translating these informal problems into formal statements using an AI model. Then, a clever filtering system weeds out low-quality or inconsistent statements, ensuring the dataset's integrity. The remaining statements are then tackled by DeepSeek-Prover, which attempts to generate formal proofs. These proofs are checked for correctness by Lean 4, a powerful proof assistant. This iterative process, where the model learns from its successes and failures, is key to DeepSeek-Prover's impressive performance. It achieved a 46.3% accuracy rate on the miniF2F test, a benchmark of formal math problems, outperforming even GPT-4. It even managed to crack 5 out of 148 problems in the challenging FIMO benchmark, a feat GPT-4 couldn't replicate. This breakthrough opens exciting possibilities for the future of mathematics. Imagine AI assisting mathematicians in verifying complex proofs, accelerating research, and even discovering new mathematical truths. While the current focus is on algebra and number theory, the team plans to expand to other areas of mathematics, promising even broader applications for this powerful AI tool. The open-sourcing of the dataset and model further democratizes access to this cutting-edge technology, paving the way for a future where AI and human mathematicians collaborate to unlock the mysteries of mathematics.
