Gemini 2.5 Pro represents a significant step forward in AI model design, combining raw power with refined reasoning capabilities that directly address complex, real-world tasks.

Upgraded AI reasoning models that pause to ‘think’ are key to the additional capabilities of Gemini 2.5, says Google.

This thinking capability was first introduced by Google in its Gemini 2.0 Flash Thinking Experimental AI model, which was released in December. To create the model, the company explored AI-building practices including reinforcement learning and chain-of-thought prompting.
