ML//benchmark//IFEval

IFEval (Instruction Following Evaluation) is a benchmark for language models that tests compliance with precise formatting, length, keyword and structural constraints, using prompts with verifiable instructions. It leaves knowledge, reasoning and style aside, isolating one dimension of evaluation, and measures only whether the model did exactly what was asked.

Its strength is also its boundary: deterministic checks make scoring reproducible, but passing the check does not prove that the response is useful.
