SUMMARY

In 30 seconds

Matthew Berman briefly introduces DeepSeek-Prover-V2 and cites a DeepSeek researcher’s benchmark claims. The results concern formal mathematical proof under specific evaluation conditions, not general success at all math problems.

  1. 1A model for mathematical proofsBerman introduces DeepSeek-Prover-V2 and highlights its mathematical capabilities.
  2. 2miniF2F and PutnamBenchA DeepSeek researcher reports nearly 90% on miniF2F and improvement on PutnamBench. The results depend on the model and evaluation budget.
  3. 3Formalized AIME problemsThe researcher also reports a nontrivial result on formal versions of selected AIME 2024 and 2025 problems.

Takeaways

  1. DeepSeek-Prover-V2 is designed for formal theorem proving in Lean 4.
  2. DeepSeek reports 88.9% on miniF2F-test for its 671B model with up to 8,192 attempts per problem.
  3. The researchers report 49 of 658 PutnamBench problems solved and results on selected formalized AIME questions.
  4. The video reports the researchers’ results and does not independently test the model.

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.

02

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.

03

AIME and comparison

Berman highlights results on formalized AIME problems and a chart comparing models. He encourages viewers to try the model.

DeepSeek’s reported proof benchmarks
SLIDE 1 / 1DeepSeek’s reported proof benchmarksThe chart compares reported miniF2F, PutnamBench and selected AIME results; evaluation settings differ.

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.
