Gemini 3 Pro

Gemini 3 Pro is Google DeepMind’s flagship multimodal AI, announced for preview on Nov 18–19, 2025. It features a 1M-token context window, PhD-level reasoning with Dynamic Thinking and a future Deep Think mode, and advanced agentic coding capabilities. Built on a transformer architecture, it natively ingests text, images, video, audio, and PDFs, outputting long-form text and code with advanced tool calling and structured outputs. It is purpose-built as Google’s most intelligent model for agentic tasks and “vibe coding,” enabling users to plan, learn, and build creative code-driven experiences across various modalities.

How to Use

Gemini 3 Pro can be accessed and used in several ways: through the Gemini App by subscribing to Google AI Plus/Pro/Ultra and selecting 'Thinking mode' for multimodal prompts; via Google Search AI Mode (US first) by choosing AI Pro/Ultra and enabling 'Thinking' for dynamic view responses; programmatically using the Gemini API or Vertex AI for function calling and multimodal payloads; integrating with Antigravity IDE or JetBrains for agentic coding tasks; selecting Gemini 3 Pro in Google Workspace (Docs, Gmail, Sheets) for drafting, summarizing, and data reasoning; and scripting builds, testing, and data prep with structured outputs using the Gemini CLI (for Ultra or API users).
