v2.19.4
Fixed
- TTS
response_formatandcontent_typesupport — OpenAI-compatible TTS providers now correctly passresponse_formatin the API request and map it to the appropriate MIME type inAudioResponse.content_type. Previously,response_formatwas never sent andcontent_typewas always hardcoded to"audio/mp3", causing failures when providers return non-MP3 audio (e.g., WAV from mlx-audio/Kokoro).- Affected providers: OpenAI, OpenAI-compatible, Azure TTS
- Default behavior unchanged: omitting
response_formatstill defaults to"mp3"
