How limits work
Each limit has:- A scope — the identity it counts against: an organization, a project, a secret key, a session, a phone number, an IP address, a request, a dashboard, or a panel.
- A kind — how it counts: a rate (requests within a time window), a concurrency cap (how many can be in flight at once), or a maximum (a fixed ceiling on a single request).
- A behavior when exceeded — most request limits return an error and you retry after a short wait; some non-critical paths degrade gracefully instead.
429 and the error code TOO_MANY_REQUESTS. Back off and retry.
Limits in effect
Agent runs
If a project is at its concurrent-run cap, a new thread is refused, and so is any run started through the API, CLI, or MCP: back off and retry. A follow-up message in an existing thread sent from the dashboard or a chat integration waits for a slot instead. Contact support to raise a project’s cap.
API
API requests are weighted — an expensive operation counts for more than a cheap one — and counted per organization and per key. Exceeding either returns
429.
Log search and dashboards
The values are fixed and listed in Log search and Dashboards. Asking questions and running queries through the API, CLI, SDK, or MCP also counts toward the API limits above.
Sandboxes
Organization and account safety
These protect signup, verification, and invite flows from abuse.
Overrides
Some limits can be raised for a specific organization or project. If a limit is blocking a legitimate workload, contact support with your organization and the limit you are hitting.Where to find the current values
The numeric thresholds are not published here because they can change. To see what applies to you:- Usage and quotas — Settings > Usage in the dashboard.
- Plan-related quantities — Settings > Billing and the pricing page.
- Per-request limits — the
429response includes standard rate-limit headers indicating when to retry.
