Concurrent generation allowance depends on account tier, current deployment configuration, and sometimes queue load.

Image-generation and image-editing routes produce still outputs instead of timed clips. Duration availability for video models may still vary as upstream providers update their capabilities, so check the generation interface for the most current options.

Rate Limits

To ensure fair usage and platform stability, rate limits are applied per account. If you encounter rate limiting, wait a moment before submitting additional generations and respect any 429 backoff guidance returned by the product.
