ComplexFuncBench Audio (OpenAI)

gpt-realtime 66.5% Dropped

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 2025-08-28. 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.
