Google Opens Gemini 3.5 Thinking Modes to All Users, Keeping Deep Think Behind $100 Tier

Summary
Google has made Gemini’s Standard and Extended thinking modes free for all users across web, Android and iOS, expanding access to features it began rolling out around I/O 2026.
Gemini 3.5 Flash and Flash Light now let users switch thinking levels in model settings, with Extended designed for deeper reasoning and more complex responses.
Extended access still faces a practical limit: it consumes tokens quickly, and Google’s variable token use by task complexity has already triggered complaints from users hitting quota caps.
Gemini 3.1 Pro’s higher-end Deep Think remains restricted to AI Ultra subscribers, a plan priced at $100-$200 per month.
The broader push toward heavier reasoning models also raises cost and environmental questions, with Google data centers emitting about 3.8 million cubic meters of carbon dioxide annually.
