TCS-Bench

Not in model cards

Models write proofs of target results from STOC, FOCS and SODA papers, given the needed context. A verification agent, checked against expert judgments, grades each proof.

The reference verifier exceeds 90% accuracy on an expert-labeled set. AINews reported a math system at 71.0%. The repo had 0 stars on November 1st, 2026.

In the authors’ words

We introduce TCS-Bench, a benchmark for evaluating Large Language Models (LLMs) on research-level Theoretical Computer Science (TCS) proof generation. TCS-Bench consists of theorem-proving tasks from papers published at top theoretical computer science venues (STOC, FOCS, and SODA). Each task provides the necessary context to derive a self-contained proof for a target result. We evaluate state-of-the-art models on this benchmark. We verify the correctness of generated proofs via a verification agent, and further benchmark the verifier against human-expert proof judgements on a set of target statements and generated proofs pairs. Our reference verifier achieves over 90% accuracy on the expert labeled set.
