Letta Rate Limits
Letta Cloud allows unlimited agents per account. Specific HTTP RPS limits are not publicly documented; Enterprise contracts unlock increased quotas. Self-hosted Letta has no Letta-imposed rate limits (only your infra capacity and downstream LLM provider limits).

It captures 2 rate-limit definitions, measuring agents and requests.
The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.
