Google I/O 2025 was dedicated to AI. At its annual developer conference, Google announced updates that put more AI into Search, Gmail, and Chrome. Its AI models were updated to be better at making images, taking actions, and writing code.

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 unveiled dozens of new AI updates at I/O. Some of them seem to overlap significantly.

Alphabet's Google kicks off its annual developer conference on Tuesday with a flurry of announcements showcasing its huge investment in artificial intelligence, while seeking to fend off concerns over the future of its business.

Last week, ahead of I/O, Google announced the Gemini 2.5 Pro Preview large language model with significantly improved coding abilities, and today the company announced that it’s updating the lighter-weight Gemini 2.5 Flash with stronger coding performance and complex reasoning capabilities.

Google I/O 2025 announcements are being followed across the world. Earlier this month, Alphabet stock lost $150 billion in market value in one day.
