50 AI music tracks for a 50-ad creative test: $6.25 on Sume
Sume Music 1.0 charges a fixed $0.125 per accepted generation, so 50 tracks for a 50-ad creative test is $6.25 no matter how long the prompts are.
50 tracks for a 50-ad creative test cost $6.25 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.
| Retakes per keeper | Generations | Total |
|---|---|---|
| 1 | 50 | $6.25 |
| 2 | 100 | $12.50 |
| 3 | 150 | $18.75 |
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.
