About

FARE (Foundational Automatic Reasoning Evaluators) is Salesforce AI Research's family of open-weight evaluator models, introduced in October 2025. They are trained with rejection-sampling fine-tuning on a large multi-task, multi-domain dataset to judge other models' outputs: pairwise comparisons, step-level error finding, reference-based and reference-free verification, and single-score ratings. FARE-20B is fine-tuned from OpenAI's gpt-oss-20b; the weights are released under CC BY-NC 4.0 for non-commercial use.
