We enforce rate limits to ensure fair usage and stable performance for all users. The rate limit specifies the maximum number of API requests that can be made within a specified time frame for a given workspace.

​
Default Rate Limit

Every account starts with the following default rate limits:
APIRate limit
TTS20 requests per second
LLM25 requests per second
Embedding50 requests per second
STT50 audio chunks per second
These limits are usually sufficient for hundreds of concurrent users in interactive use cases, such as real-time conversations, and for thousands of concurrent users in less interactive use cases.

​
