Evals & Safety
IFEval
Instruction-Following Eval, a benchmark of about 500 prompts that each contain one or more verifiable instructions, such as "write more than 400 words" or "mention the keyword AI at least 3 times".
In depth
Instruction-Following Eval, a benchmark of about 500 prompts that each contain one or more verifiable instructions, such as "write more than 400 words" or "mention the keyword AI at least 3 times". It covers 25 instruction types, and every one can be checked with code. That means scoring needs no human graders or LLM judge and gives the same result every run. It is a standard score for how reliably a model follows formatting and constraint instructions.
