v2 — Unified audio, chat, and translation endpoints

​
Unified endpoints

We consolidated the speech, text-to-speech, and conversational AI surfaces into a smaller set of unified endpoints. The old routes still work but are deprecated and now return Deprecation and Sunset response headers. They are documented under the v1 · Deprecated version.

Highlights

  • Speech to Text — a single POST /tasks/audio/transcriptions endpoint routes to the Modal (Whisper large-v3) or RunPod backend, with optional speaker diarization.
  • Text to Speech — POST /tasks/audio/speech exposes two models (orpheus-3b-tts and spark-tts), plus batch synthesis, voice discovery, and signed-URL refresh.
  • Conversational AI — POST /tasks/chat/completions is OpenAI-compatible, so the official OpenAI SDKs work by changing only the base URL and API key. It supports multi-turn conversations and streaming.
  • Translation — POST /tasks/translate (Sunflower) now translates between any pair of 32 languages, with optional source-language inference.

​
New endpoints

  • PUT /auth/profile — Update Profile
  • GET /auth/profile/status — Profile Status
  • POST /tasks/classify_language — Classify Language
