Gemini 3.1 Pro
The Research & Context Specialist
Google's Gemini 3.1 Pro pairs a 1M-token context window with Deep Research, the proactive Spark agent, and deep Gmail/Docs/Drive integration. Gemini 3.8 Flash (September 2026) is the latest Flash model; Gemini 3.5 Flash-Lite offers ultra-low-latency for high-volume use. Gemini 3.5 Pro, with a reported 2M-token context, still has not launched as of October 2026, although Google said in May it would ship in June. Google Assistant was permanently shut down on Android and Wear OS on September 4, 2026. Gemini now runs everywhere Google Assistant did.
