About OpenAI Codex
OpenAI Codex is a descendant of GPT-3 explicitly trained on billions of lines of code from GitHub and other public sources. It is designed to interpret natural language commands and generate working code in over a dozen programming languages, including Python, JavaScript, Go, and Ruby.
Codex serves as the engine behind tools like GitHub Copilot, assisting developers by auto-completing lines, writing entire functions, or even refactoring code based on comments. It understands both programming logic and human language, allowing it to bridge the gap between intent and syntax.
While originally a standalone beta API, its capabilities have largely been integrated into OpenAI's newer GPT-3.5 and GPT-4 models, which offer even stronger coding performance.
