Technical Specifications
| Feature | GitHub Copilot | Kiro |
|---|---|---|
| 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+). | Claude Sonnet 4.5 as primary model, with Auto mode that combines frontier models with prompt caching to optimize quality, latency, and cost. |
| 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. | Large context support through Claude Sonnet 4.5. Persistent context across sessions enables multi-day autonomous work without losing project understanding. |
| 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. | Standalone IDE (Code OSS-based) for macOS, Windows, Linux. CLI available for macOS and Linux. No AWS account required—sign in with GitHub, Google, AWS Builder ID, or IAM Identity Center. |
| 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. | Cloud-based, requires internet connection. Core agentic features depend on cloud AI inference. |
