Technical Specifications

Feature GitHub Copilot Gemini
Core AI Model(s) Powered by a variety of generative AI models from GitHub, OpenAI, and Microsoft. Specific models available depend on the user's plan, including Claude 3.5 Sonnet, GPT-4.1 (Free), Claude 3.7/4 Sonnet, Gemini 2.5 Pro (Pro), and Claude Opus 4, o3 (Pro+). Gemini is a family of multimodal models developed by Google DeepMind, including Gemini 2.5 Pro, Gemini 2.5 Flash, Gemini 2.0, and Gemini Nano.
Context Window Context is derived from the code within your editor, focusing on the lines immediately surrounding your cursor, other open files in your workspace, and the URLs of relevant repositories or file paths to provide relevant suggestions. The context window varies by model. For instance, Gemini 1.5 Pro supports a context window of up to 2 million tokens.
Deployment Options Available as an extension for major IDEs including Visual Studio Code, Visual Studio, Neovim, Xcode, Eclipse, and the JetBrains suite. It also integrates with the GitHub CLI, GitHub Mobile, and directly into the GitHub.com interface for Enterprise users. Gemini is primarily a cloud-based service available via its web interface and the Gemini API. An on-premises solution is becoming available through Google Distributed Cloud (GDC), which allows organizations to run Gemini models in their own data centers, including in air-gapped environments.
Offline Mode No, GitHub Copilot requires a constant internet connection to function. It sends code snippets and context to GitHub's cloud servers for processing and cannot generate suggestions while offline. No, Gemini is a cloud-based service and requires an internet connection. The on-premise GDC deployment still requires the managed hardware solution and is not a standalone offline application.
