This would be nice to have for R1 as well. Just a toggle for "Show thinking" would be fantastic.

"By default, the Gemini API doesn't return thoughts in the response. To include thoughts in the response, you must set the include_thoughts field to true, as shown in the examples."

About Deepseek R1: I'm using it via OpenRouter. The interface has a button to show the thinking, but it disappears as soon as the model writes the final answer. It would be nice to have the possibility to leave the thinking visible.
Edit: It actually happened only for the first message in the chat, continuing the conversation it is now leaving the thinking process displayed on the page. Is this a known bug or should I open a separate issue?
