ProofNet

DeepSeek-Prover-V2-671B 37.1% Only in system cards

Provers write formal proofs for 371 undergraduate theorems from analysis, algebra and topology textbooks, each with a formal statement and a natural-language proof. The proof checker grades them.

Originally in Lean 3. Prover reports such as DeepSeek-Prover-V2 use the test split, usually a Lean 4 port. Also used for autoformalization.

In the authors’ words

We introduce ProofNet, a benchmark for autoformalization and formal proving of undergraduate-level mathematics. The ProofNet benchmarks consists of 371 examples, each consisting of a formal theorem statement in Lean 3, a natural language theorem statement, and a natural language proof. The problems are primarily drawn from popular undergraduate pure mathematics textbooks and cover topics such as real and complex analysis, linear algebra, abstract algebra, and topology. We intend for ProofNet to be a challenging benchmark that will drive progress in autoformalization and automatic theorem proving. We report baseline results on statement autoformalization via in-context learning. Moreover, we introduce two novel statement autoformalization methods: prompt retrieval and distilled backtranslation.

DeepSeek-Prover-V2-671B leads with 37.1%

Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

Scores over time

All the scores we have, one dot each, so a model tested at several settings appears more than once.

Labs report it only in system cards

We read the headline results of 479 launch posts from 51 labs, and none of them list this benchmark. Some system cards do, below.

One system card reports it

Besides launch posts, we read the system cards, model cards and technical reports labs publish with a release. They report far more, including safety and frontier-risk tests.
