ComplexFuncBench Audio (OpenAI)
Speech-to-speech models solve ComplexFuncBench function-calling tasks whose text prompts OpenAI converted into speech. Covers multi-step calls, constraints, implicit parameters and long inputs.
OpenAI built it for the gpt-realtime launch on August 28th, 2025. Scoring is assumed to follow ComplexFuncBench, which checks calls against references.

gpt-realtime leads with 66.5%
Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

Scores over time
All the scores we have, one dot each, so a model tested at several settings appears more than once.
