In a post on X, Google DeepMind chief scientist Jeff Dean says the model is “trained to use thoughts to strengthen its reasoning,” and also benefits from the speed that comes along with the faster Gemini Flash 2.0 model. The demo shared by Dean shows how Gemini 2.0 Flash Thinking goes about answering a physics problem by “thinking” through a series of steps before offering a solution.

This isn’t necessarily “reasoning” in the way humans perform it, but it means the machine breaks down instructions into smaller tasks that can produce stronger outcomes.
