Provider Notes

The five named slugs have model-specific schemas. fal/speech-to-text uses fal's direct SSE inference path; fal/speech-to-text-turbo and the other named models use fal's queue API. The normalized AudioLab response is returned only after the final provider result. fal also has an open-ended model marketplace, so fal/<owner>/<model> can be pinned dynamically; AudioLab sends only audio_url for unknown schemas and does not guess support for language, timestamps, diarization, or translation. Wizper and Whisper support translation; only fal/whisper supports diarization.
