Technical Specifications
| Feature | GitHub Copilot | ChatGPT |
|---|---|---|
| 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+). | ChatGPT utilizes a range of OpenAI's models, including the GPT-4 series (GPT-4o, GPT-4.1) and the o-series for reasoning (o1, o3, o4-mini). The specific model used can vary based on the user's subscription plan (Free, Plus, Pro, Enterprise) and the selected mode. |
| 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 significantly by model and subscription tier. API and Enterprise users can access up to a 128k or 200k token context window with models like GPT-4o and o3. However, for users of the standard ChatGPT Plus web interface, the effective context window is often smaller (around 32k tokens), with larger documents being handled via Retrieval-Augmented Generation (RAG). |
| 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. | ChatGPT is primarily a cloud-based SaaS application. While a full on-premise deployment of ChatGPT is not offered, businesses can use the OpenAI API to integrate the models into their own applications. For enterprises with strict privacy needs, solutions like Azure OpenAI or third-party platforms enable private cloud or on-premise knowledge stores that can connect to OpenAI's models. |
| 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, ChatGPT requires a constant internet connection to function as it is a cloud-based service. There are open-source, third-party applications that allow users to run different, smaller language models offline, but these are not the official ChatGPT models. |
