Google Gemini โ€” AI Chat

Gemini is Googleโ€™s family of multimodal AI models, built by Google DeepMind. It powers Googleโ€™s AI chat assistant at gemini.google.com, integrates into Google Workspace (Gmail, Docs, Sheets), and is available via the Gemini API for developers.

As of mid-2026, Googleโ€™s current frontier family is Gemini 3.x โ€” see the Google Models guide for the full, regularly-updated breakdown:

ModelBest For
Gemini 3.6 FlashFastest current tier โ€” agentic tasks, production speed
Gemini 3.5 Flash-LiteLow-latency, high-volume subagent workloads
Gemini 3.1 ProDeepest reasoning (preview) โ€” research, complex coding
Gemini 2.5 Pro / FlashPrevious generation, still supported

Geminiโ€™s Pro-tier models have historically shipped with some of the largest context windows of any publicly available model โ€” check the Google Models guide for current figures, since exact numbers shift with each release.

  • Multimodal โ€” understands and generates text, images, audio, video, and code
  • Google integration โ€” works natively within Gmail, Google Docs, Sheets, Slides, Meet
  • Massive context โ€” analyze entire codebases or document libraries in one prompt
  • Search grounding โ€” can search Google in real time for up-to-date information
  • Gemini CLI โ€” command-line access to Gemini for developers (see Gemini CLI)
