VCoT-Bench-Type - Assertion: leaderboard

Metric: Weighted completion accuracy (%) on the tasks with every inline assertion removed of VCoT-Bench-Type (439 tasks in the sub-benchmark), Verus proof-completion tasks built by removing verification steps from solver-lifted Rust proofs (VCoT-Lift), zero-shot greedy decoding (temperature 0 except GPT-5 mini); a completion scores 1 if Verus accepts its syntax and a GPT-5 mini judge rates it semantically equivalent to the lifted ground-truth proof, 0.5 if only semantically correct, 0.25 if only syntactically correct, 0 otherwise; higher is better. Source: arxiv.org. Saturation forecast: Around 2029. 11 models tracked.
