DeepSeek-Prover-V2
Berman introduces the model and its focus on mathematics. The release concerns formal theorem proving.
DeepSeek, the company behind DeepSeek-R1, has released DeepSeek-Prover-V2. I am impressed by its reported performance on mathematics. The model is aimed at formal theorem proving in Lean 4, a more specific task than solving arbitrary math equations.
Reported benchmark results
He cites a researcher’s claims on miniF2F and PutnamBench. The comparison uses specific proof-search conditions.
According to a DeepSeek researcher, the model solves nearly 90% of miniF2F problems and substantially improves results on PutnamBench. The [technical report](https://arxiv.org/abs/2504.21801) reports 88.9% on the miniF2F test set for the 671B model with up to 8,192 proof attempts per problem, and 49 of 658 PutnamBench problems solved. These are researcher-reported results under particular evaluation conditions, not a single-attempt success rate.
AIME and comparison
Berman highlights results on formalized AIME problems and a chart comparing models. He encourages viewers to try the model.
The researcher also reports a nontrivial success rate on formalized AIME 2024 and 2025 problems. The report’s ProverBench includes 15 selected AIME problems; the comparison shown distinguishes formal proof generation from an informal answer task. The chart shows substantial differences between the listed models, and I encourage viewers to try DeepSeek-Prover-V2. This short video does not independently test the claims.
