Google is adding a Gemini 2.5 Pro Experimental model for users of the free version of the chatbot. It is currently only available on the web, but the company plans to expand support to smartphones soon.
Gemini 2.5 Pro is Google's new reasoning model that can check its own answers. Google unveiled Gemini 2.5 Pro last week, calling it "the smartest AI model."
Free users will have a smaller context window and the chatbot will run a little slower. However, in all other respects the model is not inferior in performance to the paid version.
