The model selector in Chatex lets you choose the best available AI model family for each task. You can switch between supported models for writing, coding, analysis, research, and everyday chat.
How to use the model selector
Open the chat interface.
Click the dropdown next to the current model name.
Select the model family you want to use.
Model availability depends on whether you are using free access or a paid subscription:
Free access: entry-level chat access while free access remains.
Paid subscriptions: access to supported premium models and features. Paid options are a 7-day paid trial that auto-converts to monthly unless canceled, a quarterly subscription that starts immediately, or a 6-month subscription that starts immediately.
