CodexWhat is Codex?
Codex is an advanced AI code generation model developed by OpenAI and integrated into GitHub Copilot through a partnership with Microsoft. It translates natural language prompts into working code across multiple programming languages, transforming how developers write, understand, and maintain software.
Codex is trained on billions of lines of public code and natural language from sources like GitHub, enabling it to understand developer intent and assist in real-time coding. It’s built on GPT architecture, fine-tuned specifically for programming tasks.
