## Improved

Rate limits for Synthesia's APIs have been updated:

- [Rate limits](https://docs.synthesia.io/reference/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](https://docs.synthesia.io/reference/introduction#/read-vs-write-operations).

Review the updated rate limits in the [API Introduction page](https://docs.synthesia.io/reference/introduction#/rate-limits).
