tips

Default Music Generate endpoint: Use this route for the standard music generation flow. MiniMax is an integrated provider with its own endpoint, not the default model for this API.

Two Generation Modes:

  • Inspiration Mode: Use gpt_description_prompt to generate music from a text description
  • Custom Mode: Use prompt, style, and title for detailed control

Model Selection: Choose from chirp-v4-0, chirp-v4-5, chirp-v4-5-plus, chirp-v5, or chirp-v5-5 for different quality levels. See Credit Consumption by Model for model details and credit costs.

Next step: After calling this endpoint, use the Music Generate Task Status API to poll task progress and retrieve audio URLs.
