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 is based on the same foundation as Gemini 2.5 Pro, but it increases the "thinking time" with greater parallel analysis. According to Google, Deep Think explores multiple approaches to a problem, even revisiting and remixing the various hypotheses it generates. This process helps it create a higher-quality output.
