Google’s Gemini Diffusion demo didn’t get much airtime at I/O, but its blazing speed—and potential for coding—has AI insiders speculating about a shift in the model wars.

Google on Tuesday revealed new Android development tools, a new mobile AI architecture, and an expanded developer community. The announcements accompanied the unveiling of an AI Mode for Google Search at the Google I/O keynote in Mountain View, California.

Gemini 2.5 Flash plays the role of the default model in the Gemini chatbot now. It's supposed to be the fast, cost-efficient model for daily use. Google says it’s better than its predecessors, like Gemini 2.0 Flash, in terms of understanding images and text while still being much cheaper to run.

Google says the release version of 2.5 Flash is better at reasoning, coding, and multimodality, but it uses 20–30 percent fewer tokens than the preview version. This edition is now live in Vertex AI, AI Studio, and the Gemini app. It will be made the default model in early June.

Volvo has announced that its vehicles will be among the first to make the switch from Google Assistant to Gemini.

On Tuesday at Google I/O 2025, the company announced Deep Think, an “enhanced” reasoning mode for its flagship Gemini 2.5 Pro model. Deep Think allows the model to consider multiple answers to questions before responding, boosting its performance on certain benchmarks.

Google has launched a new Gemini AI Ultra AI subscription that costs $250 per month: Here's what you get from the most expensive tier.

Following the announcement that Gemini is coming to cars, Volvo is using I/O 2025 to announce a new expanded partnership with Google. The companies' new deal makes Volvo's cars reference hardware for future Android Automotive OS development,
