Google has unveiled Gemini 2.5, the new family of AI reasoning models with chain-of-thought prompting. The first in the group is the Gemini 2.5 Pro Experimental will be available now on Google AI Studio and for Gemini Advanced users on the Gemini AI chat interface.
“For a long time, we’ve explored ways of making AI smarter and more capable of reasoning through techniques like reinforcement learning and chain-of-thought prompting. Building on this, we recently introduced our first thinking model, Gemini 2.0 Flash Thinking,” Koray Kavukcuoglu, CTO at Google DeepMind said in the blog post making the announcement. “Now, with Gemini 2.5, we’ve achieved a new level of performance by combining a significantly enhanced base model with improved post-training,” he added.
Google will be integrating these “thinking capabilities” directly into all their new AI models going forward.
Gemini 2.5 Pro is also multimodal in its nature and can process text, audio, images, videos and code repositories. The model also currently has a 1 million token context window which is one of the largest context windows available for experimental models on Gemini. The context window will be expanded to 2 million tokens soon, the company has said.
Google has also claimed that Gemini 2.5 Pro has beat other leading AI reasoning models on several benchmarks including code editing, software development and a multimodal test that has questions on maths, humanities and natural sciences.
Pricing for the Gemini 2.5 Pro will be announced by Google within the coming weeks.
Earlier in March, Google released Gemma 3, their latest small language model for devices.
