Rate Limits

Limit types

• Concurrency limits: Maximum number of simultaneous video generations. The default is 2 concurrent generations. If you need higher concurrency, contact sales.

• Rate limits: Maximum number of async (V2) jobs queued per organization. Exceeding this queue limit returns 429 with rate_limit_error.

Error response

When a limit is exceeded, the API returns 429 Too Many Requests. Concurrency limit errors include a Retry-After header indicating seconds to wait.

Error types:

• concurrency_limit_error: Too many concurrent requests (sync API)
• rate_limit_error: Queue limit exceeded (async API)
