Upgraded to DT 4.2. AI Chat not responding

I just upgraded to 4.2, and my Claude connection isn’t working as before. I have a file highlighted, and the response is simply “model: Claude 4 Sonnet” to anything I type.

Any advice? Do I need to create a new API key?

Does it work after selecting model in the settings or the chat assistant?

Thank you. That’s it. I didn’t know to hit this icon. Doing so allows me to pick the model.
