## API Improvements

Rate limits for Synthesia's APIs have been updated:

* [Rate limits](/docs/video-api-introduction#rate-limits) are now tiered, with the highest tier now offering up to 2x higher limits than before.
* Rate limits differ for [read vs. write operations](/docs/video-api-introduction#read-vs-write-operations).

Review the updated rate limits in the [API Introduction page](/docs/video-api-introduction#rate-limits).
