SAN FRANCISCO – OpenAI has introduced Codex, an autonomous AI agent designed too write, correct, and document code using a GitHub repository. The announcement was made May 16.
Codex: An Autonomous Coding Assistant
Codex, powered by Codex-1, an optimized version of the O3 model, leverages reinforcement learning on real-world programming tasks. Each agent operates within a dedicated, isolated cloud container, preloaded with user code and disconnected from the internet. This allows Codex to read and modify files, and run tests within a secure habitat. Tasks can range from 1 to 30 minutes, depending on complexity.
According to OpenAI, Codex can generate new code features, answer questions about project architecture, perform complex refactoring, write unit tests, and even create technical documentation. The agent analyzes recurring code problems and configuration inconsistencies, suggesting improvements, detecting and correcting bugs, optimizing performance, and generating pull requests.

Integration with ChatGPT
Codex is integrated directly into ChatGPT via a dedicated side section. Developers can interact with the agent by clicking “Code” to initiate a new development task or “Ask” to query an existing repository.Each task is performed independently within the isolated cloud environment. Users can monitor progress in real-time and receive a report of completed operations.
Once a task is complete, users can request revisions, open a pull request to GitHub, or integrate changes into their local environment. Codex can also be guided by an agent file (similar to a README file) specifying code conventions, test instructions, and project practices.

Availability and Pricing
The agent launched May 16 for ChatGPT Pro, company, and team users, with plans for expansion to more users and educational institutions in the coming weeks. The service will initially be offered for an additional cost with request limits, and users will have the option to purchase additional requests.
Codex will also be available in the API under the name `codex-mini-latest`. The model is accessible via API Responses and is billed at $1.50 per 1 million entry tokens and $6 per 1 million output tokens, with a 75% cache discount. It can be used for simple code factoring tasks, documentation generation, and bug correction.
Transforming the Developer Profession
OpenAI envisions a future where developers strategically manage projects while delegating repetitive or technical tasks to intelligent agents. The goal is to enable engineers to focus on innovation and creativity, allowing AI to manage routine aspects of software development. OpenAI anticipates fluid collaboration between humans and agents, working asynchronously and providing proactive updates.
While Codex automates certain tasks and saves time,OpenAI emphasizes that it does not replace developers. The company remains intentionally vague about the long-term impact, concluding with the statement: “It’s just The Beginning.”
