Faithform-AF Benchmark C of FaithformBench: Benchmarking Faithfulness of Mathematical Chain-of-Thought Autoformalisation (Cornish, Ghinassi, et al., 2026). Faithform-AF contains the per-instance outputs of four fine-tuned autoformalisers (Goedel 8B, Kimina 7B, StepFun 7B, Herald 7B) applied to every verifiable reasoning step of FaithformBench and FaithformBench-Regex. Each instance includes the raw autoformaliser output, the Lean 4 theorem as processed by the prover… See the full description on the dataset page: https://huggingface.co/datasets/ighina/Faithform-AF.
