# Update Project

`PATCH /projects/{project_id}`

Update a project's metadata.

Only provided fields will be updated. Project names must remain unique
per team (the ``unique_active_project_name_per_team`` index): no two
projects in the same team may share a name. User must be a member of
the project's team.

## Path parameters

- `project_id` string, uuid, required

## Request body

- ProjectUpdate — Request model for updating a project. ``autonomy_enabled`` is not an accepted field — it is derived from ``adaptive_cadence`` and must not be sent directly. Sending an unknown field (e.g. the old ``autonomy_enabled``) raises a 422 so callers learn to migrate to ``adaptive_cadence``.
  - `name` string, nullable — New name for the project
  - `icon` string, nullable — New icon identifier for the project
  - `repo` string, nullable — New repository reference or URL
  - `description` string, nullable — New project description
  - `tag` string, nullable — Short kebab-case label set by clustering agent
  - `observations` string, nullable — Free-text agent notes about patterns observed
  - `active_model_id` string, nullable — Active model ID for inference
  - `selected_model_id` string, nullable — [Deprecated] Use active_model_id instead.
  - `visibility` 'private' | 'team', nullable — Who can see this project: private (creator only) or team (all team members).
  - `adaptive_cadence` 'off' | 'daily' | 'weekly' | 'monthly' — User-facing cadence preset for autonomous adaptive finetuning runs.
  - `router_type` string, nullable — When set, makes this project a router that selects a model per request. Must be a registered router id.
  - `routing_params` object, nullable — Router policy configuration; validated against the router_type schema.
