The “Thinking Level” option in the Gemini app has been updated to a new “Advanced Thinking Mode” selection specification, now a simple ON / OFF toggle. This update is currently rolling out on the web version of the Gemini app. In conjunction with the developer event “Google I/O 2026” held in May 2026, Google refreshed the AI model for its Google AI “Gemini” app and introduced a new “Thinking Level” option for selecting reasoning capabilities. Two months have passed since then, and the “Thinking Level” option has now been updated. The original option allowed users to choose between “Standard” or “Extended” for deeper deliberation. The new specification has been revamped into a simple ON / OFF toggle, where OFF corresponds to “Standard” and ON corresponds to “Extended.” The Android and iOS versions of the Gemini app still feature the previous interface, but they are expected to be updated to the new specification soon.
