What IFBench measures and how its scores work.
IFBench is an Instruction Following Benchmark.
It measures a model's ability to follow complex instructions using the Score metric, reported as a ratio.
Scores are shown in ratio. This benchmark is not independently verified and has an evidence level of B.
