Credits and limits
4 minute read · Updated 2026-09-11
Reads are free; generation is metered. Credits are reserved when work starts and refunded if it fails, so a crashed render does not bill you. Your plan sets the monthly allowance and which capabilities are unlocked at all.
What costs credits
| Free | Metered |
|---|---|
| Listing and reading anything | Image generation, including cover art and photo studio |
| Creating and editing records — artstyles, briefs, personas, posts | AI image extension (ai_extend); a plain resize is free |
| Polling and cancelling jobs | Every render pipeline — studio, lyric video, quick video, clip assembly, YouTube |
Current balance and the per-plan monthly allowance live on the billing page in the app. They are not repeated here, because numbers copied into documentation are numbers that go out of date.
Reservations and refunds
Credits are reserved when a job is created, before the work is dispatched. If the job fails — whether the pipeline threw or the process died — the reservation is released. You are billed for work that completed, not for work that was attempted.
This is why relaunching a slow job is expensive: the first job is still holding its reservation, and the second takes another.
Plan gates
Some capabilities are not a question of credits but of plan. API access itself is one of them — it requires Pro or Studio, and is re-checked on every request rather than only when the token was minted.
- MCP and API access — Pro and Studio only.
- Video generation and high-quality export — Pro and Studio.
- Lyric videos, premium image models, and watermark-free output — Indie and above.
- How many artists a workspace may hold — set per plan.
Throughput
There is no published request-rate limit on the MCP endpoint, but generation is bounded in practice by the render worker and by upstream model concurrency. Several heavy pipelines launched at once will queue rather than run in parallel.
Poll on an interval measured in tens of seconds. Polling in a tight loop does not make a render finish sooner.
