Model Selection
Each AI provider offers multiple models with different capability and cost profiles. You can select the model for each provider independently from the Provider tab.

How to Change the Model
- Go to Admin → Provider tab
- Enter the model name in the OpenAI Model or Anthropic Model field
- Click Save Provider Settings
The model is applied to all new sessions immediately.
Which Model is Active?
The active model is whichever provider is currently selected. If Anthropic is selected, the Anthropic model field determines which model runs. The OpenAI model field is saved but inactive until you switch providers.
Cost Considerations
Model costs vary significantly. For a live client-facing deployment, claude-sonnet-4-5 (Anthropic) or gpt-4o (OpenAI) provide the best balance of quality and cost. Monitor your API usage dashboard on your provider's portal to track spend.
