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

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).

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.
