Google released its first publicly available "multi-agent" AI system, which uses more computational resources, but produces better answers.

Google is rolling out its most advanced version of Gemini yet, called Deep Think. It's available exclusively to AI Ultra subscribers on the Gemini app.

Deep Think builds on the version of Google’s Gemini 2.5 model that recently clinched a gold medal standard at the 2025 International Mathematical Olympiad (IMO).
