Conditional rules: Requires name and 6–24 public audioUrls (MP3, WAV or M4A). Training can take up to about 20 minutes; the result carries output.customModelId, which later music, extend, cover and other V6 actions accept as customModelId.

Only send fields relevant to this action. When a request references sourceTaskId, the source must be a successful Suno task owned by the same account.

You can instead provide a top-level webhook. The task reaches finished, failed or expired; failed generations are refunded automatically. Data actions return output, while media actions return files.
