Tsinghua and Moonshot AI release TCSExam, a 100-task theoretical computer science benchmark
Overview
Tsinghua University and Moonshot AI release TCSExam, a benchmark of 100 expert-reviewed tasks across four tracks: Lean theorem proving, solver engineering, record-setting constructions, and 30 open conjectures.
Without supplied lemmas, GPT-6 Astra fully proved theorems in 70.0% of attempts and Kimi K3.1 Pro in 38.3%, according to the report.
On the 30 open conjectures, the same models resolved none. The few accepted conjecture submissions adapted counterexamples and proofs that OpenAI had already published.
