# Limits

Limits that apply to authoring, deploying, and running Agents are detailed below.

Many limits are inherited from those applied to Workers scripts and/or Durable Objects, and are detailed in the [Workers limits](https://developers.cloudflare.com/workers/platform/limits/) documentation.

| Feature                                                | Limit                                                                                        |
| ------------------------------------------------------ | -------------------------------------------------------------------------------------------- |
| Max concurrent (running) Agents per account            | Tens of millions+ [1](#user-content-fn-1)                                                    |
| Max definitions per account                            | \~250,000+ [2](#user-content-fn-2)                                                           |
| Max state stored per unique Agent                      | 1 GB                                                                                         |
| Max compute time per Agent                             | 30 seconds (refreshed per HTTP request / incoming WebSocket message) [3](#user-content-fn-3) |
| Duration (wall clock) per step [3](#user-content-fn-3) | Unlimited (for example, waiting on a database call or an LLM response)                       |

To request an adjustment to a limit, complete the [Limit Increase Request Form ↗](https://forms.gle/ukpeZVLWLnKeixDu7). If the limit can be increased, Cloudflare will contact you with next steps.

## Footnotes

1. Yes, really. You can have tens of millions of Agents running concurrently, as each Agent is mapped to a [unique Durable Object](https://developers.cloudflare.com/durable-objects/concepts/what-are-durable-objects/) (actor). [↩](#user-content-fnref-1)
2. You can deploy up to [500 scripts per account](https://developers.cloudflare.com/workers/platform/limits/), but each script (project) can define multiple Agents. Each deployed script can be up to 10 MB on the [Workers Paid Plan](https://developers.cloudflare.com/workers/platform/pricing/#workers) [↩](#user-content-fnref-2)
3. Compute (CPU) time per Agent is limited to 30 seconds, but this is refreshed when an Agent receives a new HTTP request, runs a [scheduled task](https://developers.cloudflare.com/agents/api-reference/schedule-tasks/), or an incoming WebSocket message.
