Agents and accounts

Model and effort

Choose the model and effort for each agent in each session.

Pick a model

Click an agent's chip above the composer to pick its model:

• Claude: Fable, Opus, Sonnet, Haiku, or type any model name.
• Codex: the models in your Codex's own list.
• Cursor and OpenCode: what their models command lists.

Pick the effort

In the same menu, choose the effort:

• Claude: low to max.
• Codex: the levels each model supports.

The chip shows your choice, for example @codex gpt-6-astra · high.

Per session

You can change it any time. Each session keeps its own choice, and every reply shows the model and effort it used.
