OpenAI Codex is an AI system that translates natural language into code, now generally available with new features for developers and teams. It powers GitHub Copilot and supports over a dozen programming languages including Python, JavaScript, Go, and more. Codex can interpret simple English commands and execute them, enabling natural language interfaces to software and APIs.

The latest version, GPT-5-Codex, offers faster and more accurate coding assistance, accessible via an API and a new SDK that integrates the Codex agent into custom workflows and apps. Codex also features a Slack integration, allowing teams to delegate coding tasks and get answers directly within Slack channels.

Administrators benefit from enhanced tools like environment controls, usage monitoring, and analytics dashboards to manage Codex usage at scale. Codex is used globally by startups and enterprises alike to speed up code reviews, automate code cleanup, and reduce manual coding effort.

Technically, Codex has a larger memory for Python code (14KB) than its predecessor GPT-3, allowing it to consider more context when generating code. It runs as a cloud-based agent and also offers a local CLI tool for coding assistance in terminal environments.

OpenAI continues to improve Codex’s safety and reliability, scaling access carefully while supporting developers with documentation and community resources. Codex lowers barriers to programming by automating repetitive tasks and helping users map problems to existing code efficiently.
