Gemini Code Assist
Gemini Code Assist is Google’s AI coding assistant for integrated development environments (IDEs) and Google Cloud. It runs on Gemini 3 models with a one-million-token context window. Gemini 3.5 Flash is generally available in VS Code and IntelliJ, where Gemini 3.1 Pro is also in preview.
Inside Visual Studio Code, JetBrains IDEs, and Android Studio, it provides context-aware chat, code completions, generation and transformation, unit test suggestions, and help with debugging and documentation, with source citations for longer quoted material. Since June 18, 2026, these extensions serve only paid Gemini Code Assist Standard and Enterprise subscriptions. Google moved the Gemini Code Assist for individuals, Google AI Pro, and Google AI Ultra tiers to Antigravity and Antigravity CLI.
Outside the editor, Gemini Code Assist on GitHub reviews pull requests automatically and answers follow-up questions when tagged with /gemini in a comment.
Its agent mode, currently in preview, can run multi-step tasks using built-in tools and Model Context Protocol (MCP) servers, and you can add file context with the @filename syntax.
Its paid Standard and Enterprise editions include IP indemnification and enterprise security controls, and the Enterprise edition adds code customization that adapts suggestions to a company’s private repositories. Both editions also cover Gemini CLI, which provides the same assistance in the terminal.
