Gemini Thinking Levels

A control in Gemini that lets you choose how long it reasons before answering, now free for everyone across web, iOS, and Android.

Two levels: Standard, the default and best for most questions, and Extended, which gives more time and step-by-step reasoning for complex topics.
Available on Gemini 3.5 Flash and 3.5 Flash-Lite; Gemini 3.1 Pro adds a third Deep Think level limited to AI Ultra subscribers.
The control is now free for all users, after first rolling out around Google I/O 2026.

Deciding how much reasoning a question needs instead of getting one fixed response speed.

A task is complex enough to need step-by-step reasoning, so you switch from Standard to Extended.

Anyone using Gemini for both quick questions and harder, multi-step problems.

Staying informed is great. Staying ahead is better.
