What Are the Limits and Lifetime for Assistant Threads?

Below is a summary of what the public API documentation tells us regarding threads:

Maximum Number of Threads

• Hard Limit:
  There isn’t any documented hard limit on the number of threads that you can create. The documentation does not specify whether any constraints are applied at the level of a particular assistant or per API key.

• Practical Considerations:
  Although no explicit limit is mentioned, if your application creates a large number of threads it may be worth managing thread lifecycle (e.g., by deleting threads that are no longer needed) to ensure optimal resource management and avoid unforeseen constraints.

Thread Lifetime

• Expiration:
  The documentation does not provide any information about a built-in lifetime or expiration period for a thread. Threads remain available until you explicitly delete them via the Delete thread endpoint.

Recommendation

Given the above points, if you plan on creating many threads, it might be wise to programmatically delete those that are no longer in use. This way, you can manage your resources effectively, even though the current documentation does not enforce a specific maximum or automatic cleanup.

If you need more detailed or updated information, consider checking the latest documentation or reaching out to the platform support channels.
