Chat & AI
Selecting a model
Choose which AI model answers, read the speed, intelligence and price signals, and know why some models are greyed out.
Step 1
Open the model picker
The first button in the composer shows the logo of the current model's provider. Hover it for the model name, press it to open the picker. It opens above the composer on a computer and as a sheet on a phone, with keyboard focus on the current model.
Press Enter to send, Shift+Enter for new line
Step 2
Lay it out your way
The picker lists Anthropic, OpenAI and Google models. The first pair of buttons on the right switches between Grid, all three providers side by side, and Accordion, one provider open at a time as shown here. The second pair switches between Compact, names only, and Detailed, which adds the signals below. Both choices are remembered on this device. On a phone only the Compact and Detailed pair is shown.

Ask your organisation admin if you need them. If your role allows no models, the picker says No models are available for your role. If it cannot check, it says Your model access could not be loaded. with Try again. A saved model you can no longer use is marked not available for your role, in the hover text of the model button, until you pick another.
