# Limits

Learn about PixAI API rate limits, concurrency limits, and current feature limitations.



Rate limits [#rate-limits]

* Each API account allows up to 10 tasks in `waiting` status at once. `running` tasks are not counted, and the cap can be raised per account.
* We don't currently enforce a request rate limit on API calls. Please use the API responsibly—for example, use exponential backoff for retries and avoid polling more frequently than once every 1.5 seconds.

Feature limitations [#feature-limitations]

* Video generation is not supported.
* PixAI Reference Pro, PixAI Edit, and PixAI Edit Lite are not supported yet (these features are under active development).
