3 tracks for a three-song demo reel cost $0.3750 on Sume Music 1.0: a fixed $0.125 for each accepted generation.

Sume's music docs (read 2026-10-06) say the price does not change with prompt length or optional image conditioning. The rate card prices it as the fal list price of $0.10 per audio (Lyria 3.5) at the standard margin.

How does the cost scale with retakes?

A rejected track is a new generation, so budget for retakes.

What should I check?

Music is generated asynchronously like other jobs; poll or use a webhook.

  • The price is per accepted generation, not per second of audio.
  • Pin the prompt tempo and mood so retakes converge.
  • Confirm the endpoint and limits in the docs before a batch.
