# Create Custom Agents

> Learn how to create custom agents

Custom agents can be created only via the UI. Visit [you.com/agents](https://you.com/agent) and create a new custom agent with your personalized parameters:

Choose whether to enable the tools or not:

<Warning>
  **WARNING**: The [Custom Agent API](/api-reference/custom-agent) currently does not support custom agents that use a foundational model with advanced research and reasoning enabled.
</Warning>

<Note>
  **NOTE**: You can manage the tools only in the UI by enabling or disabling them. They can not be managed via the API.

  See [Web Search Tool](/tools/web-search-tool), [Research Tool](/tools/research-tool), and [Compute Tool](/tools/compute-tool) to learn more about tools.
</Note>

When you create new agents, the platform automatically populates the **Agents** section with all of the agents you've created. This is where you can retrieve each agent's ID:

Paste the ID in the `agent` parameter [to call it via API](/api-reference/custom-agent#body-agent).
