Changelog

​
June 2026

​
Suno Audio Upload → Full Song

Uploaded audio can now be extended into a full song. Upload your audio (task_type: upload), then pass the returned clip id as continue_clip_id in a music task — see Audio upload. This also fixes continuation requests, which previously failed upstream. Generating a new song in a different style from an uploaded reference (an “audio cover”) is not yet supported.

​
Suno Custom Instrumental

Custom mode now supports style-driven instrumentals. Provide tags and set make_instrumental: true with no prompt to generate an instrumental from style tags alone — see Create Task → Custom Mode. A music request with no prompt, tags, or gpt_description_prompt is now rejected with a clear 400 instead of a generic upstream error.

​
Volume Top-up Rewards

Larger top-ups now earn bonus credits automatically:
  • +5% on 500–500–999, +10% on 1,000–1,000–2,999, +12% on $3,000+.
  • The bonus is granted when payment is confirmed (e.g. a $500 top-up → 52,500 credits). See Credits.
  • Self-serve top-up remains capped at 1,000;for1,000; for 1,000+ volume pricing, contact us.

​
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.

​
April 2026

​
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
