GitHub Copilot and ChatGPT are the two most common AI tools in a developer's toolkit, but they use your internet connection in very different ways. Understanding the difference helps you pick the right tool for spotty connections — and the right plan for your workflow.
Copilot is embedded in your editor and fires off small autocomplete requests constantly as you type. Each request is tiny, but there are many of them, and each one is a round trip. This means Copilot is extremely sensitive to latency and packet loss. On a bad connection, suggestions arrive late or not at all, and the tool feels broken.
ChatGPT-style chat interfaces send fewer, larger requests. You write a whole question, get a whole answer back. Chat is more forgiving of latency but more sensitive to bandwidth during longer responses. For a full feature comparison to help you decide which tool fits your workflow, this Kommunicate comparison of GitHub Copilot vs ChatGPT covers both sides well.
