Models

Models shape how your agent reasons, writes, and decides what to do next. Choose a model based on the work you expect the agent to handle: everyday triage, deep research, long-context planning, code changes, or fast lightweight responses.

The model picker includes a short list of common models and a More models menu for additional options. Availability can vary by workspace; models marked unavailable in the picker cannot be selected.
