OpenAI Codex is an AI coding agent from OpenAI for software development, such as writing code and fixing bugs. Codex is available through ChatGPT on web, desktop and mobile, as the Codex CLI, as an IDE extension and as Codex Cloud, where tasks run in a separate environment containing your repository. Developers can also embed Codex through an SDK and a GitHub Action, and connect it with GitHub, GitLab, Slack and Linear. Permissions and sandboxing are configurable.
OpenAI is headquartered in San Francisco, California, and is a US company (OpenAI Group PBC). This means US law, including the CLOUD Act, may apply to code and prompts you process through the service. The Codex CLI is open source under the Apache 2.0 licence; the cloud environment and the desktop app are not. The documentation covers topics such as governance, a Compliance API and audit events. Before using it with source code or personal data, check with the vendor where and under what terms data is processed.
