CrypFormBench - Completion: leaderboard

Formal-model completion on CrypFormBench (2026), a formal cryptographic analysis benchmark over seven verifier languages: the model fills in a masked part of a formal model, scored 0 to 100 by combining the rate of models the tool executes with the accuracy and F1 of the verification outcomes against the gold verdicts, averaged over languages. Higher is better.

Metric: Completion score (0-100) on CrypFormBench (700 instances over 677 cryptographic schemes and 7 formal verifier languages: Scyther, Tamarin, AVISPA, ProVerif, Maude-NPA, CryptoVerif, EasyCrypt): fill in a masked part of a formal model; the harmonic mean of the tool-executable rate and the harmonic mean of verification-outcome accuracy and F1 against the gold tool verdicts, averaged over languages; higher is better. Source: arxiv.org. Saturation forecast: Estimated already saturated. 9 models tracked.
