Codex is an artificial intelligence model developed by OpenAI that translates natural language instructions into executable code across multiple programming languages.

• Generates functional code snippets from comments or docstrings using a transformer-based architecture trained on public GitHub repositories.
• Supports polyglot development including Python, JavaScript, Ruby, PHP, and Go by leveraging a large-scale language model (LLM) framework.
• Facilitates code refactoring, bug fixing, and translation between different syntax standards to improve developer workflow efficiency.
• Executes complex logic tasks such as data manipulation, API integration, and algorithmic problem solving from high-level descriptions.

Codex integrates with development environments via the OpenAI API and serves as the primary engine for GitHub Copilot. It utilizes the HumanEval benchmark to validate code accuracy through automated unit testing.

Ideal for rapid prototyping, automating boilerplate generation, and assisting in legacy code modernization.
