Udio Input Validation

The Udio task input is now validated at the API layer for clearer errors:
  • Submitting Udio tasks with Suno-style fields (gpt_description_prompt, make_instrumental) now returns 400 Bad Request with a message that names the right field — instead of the previous generic 502 "Upstream provider error".
  • The validation message links to the Udio Model docs so first-time users can correct their request on the next try.
  • No change to existing Udio integrations that already use the prompt field.

​
Udio Model Support

sunor now supports the Udio AI music model alongside Suno. Use "model": "udio" in your task request.
  • Task type: "music" only (regular mode) — see Udio Model for the full reference.
  • Pricing: 5 credits per generation ($0.05).
  • ~2 audio tracks returned per call (same as Suno’s music task).
Lyrics-only generation, audio upload, and clip concatenation are not yet supported for Udio. Use the Suno model for those.

​
Suno V5.5 Support

sunor now uses Suno V5.5 (chirp-fenix) as the default model for music generation. V5.5 brings improved audio quality, better vocals, and more accurate style adherence.
  • No API changes required — your existing code works as-is
  • Same pricing — 10 credits per music generation
  • The model version is set automatically; no need to specify it in requests
