Gemini 3 Pro

What is Gemini 3 Pro

Gemini 3 Pro is Google DeepMind’s flagship multimodal foundation model, built on a transformer architecture. It ingests text, images, video, audio, and PDFs, and outputs long-form text and code. It is designed for deep reasoning, agentic coding, and handling a 1M-token context window.

How to use Gemini 3 Pro

Gemini 3 Pro can be accessed through several platforms:

• Gemini App: Subscribe to Google AI Plus/Pro/Ultra and select Gemini 3 Pro (Thinking mode) for multimodal prompts.
• Search AI Mode: In Google Search, enable “Thinking” to receive dynamic view or visual layout responses.
• API / Vertex AI: Use the Gemini API or Vertex AI for programmatic access, supporting function calling, JSON output, and multimodal payloads.
• Gemini Agent & IDE: Utilize the Antigravity IDE or JetBrains integration for agentic coding tasks involving terminals, editors, and browsers.
• Workspace: Access Gemini 3 Pro within Google Docs, Gmail, and Sheets for drafting, summarizing, and data reasoning with extended context.
• CLI / DevTools: Employ the Gemini CLI for scripting builds, testing, and data preparation with structured outputs.
