CodeGPT AI is an AI programming assistant plugin that serves as a pair programming partner for developers, integrated into IDEs such as VS Code, delivering code generation, explanations, debugging, and optimization capabilities.
The plugin offers a free tier (30 interactions per month). Advanced features such as unlimited interactions and AI proxy mode require subscribing to the BYOK plan (about $8 per month). Using AI features typically requires users to configure their own API keys and cover third-party API costs.
It supports over 80 programming languages and official plugins for Visual Studio Code and JetBrains IDEs (such as IntelliJ, PyCharm).
Its core mode allows you to use your own API keys (BYOK), meaning code and query data are sent directly to the AI service providers you choose (such as OpenAI), and you retain full control over your data.
CodeGPT AI emphasizes bringing your own API keys and flexibly selecting among multiple AI models, while GitHub Copilot is a subscription service deeply integrated into the GitHub ecosystem.
In supported versions, you can issue specific commands (like /CodeInterpreter) to have the AI write and execute code in real-time, enabling a unified workflow for data analysis, plotting, and debugging.

ChatGPT is a powerful conversational AI platform created by OpenAI, offering advanced natural language understanding and generative capabilities. It helps users write high-quality content, generate ideas, answer complex questions, build and debug code, and streamline daily workflows. As a versatile AI assistant, ChatGPT supports productivity tasks for individuals, teams, and enterprises.

GitHub Copilot is an AI programming assistant developed jointly by GitHub and OpenAI, helping developers significantly improve coding efficiency and quality through code completion, intelligent conversations, and automation capabilities.
