"Codex CLI is an open-source coding agent from OpenAI, written primarily in Rust, that runs locally on your computer. Codex IDE extension is a coding agent that runs in Visual Studio Code and its forks, such as Cursor and Windsurf. Codex Web, which connects to Codex Cloud, can work on tasks in the background, in parallel, using its own cloud-based environment."
"All the variations of Codex rely on OpenAI models, such as GPT-5 and GPT-5-Codex, although they can be configured to use other OpenAI-compatible model providers such as Ollama, Mistral AI, and Microsoft Azure. Codex adds code-specific features, such as support for GitHub, connections to Model Context Protocol (MCP) servers, and the ability to modify files in your current working directory. Most Codex clients can delegate tasks to the cloud, although the Codex CLI doesn't yet have that capability."
Codex provides a CLI, an IDE extension for Visual Studio Code and its forks, and a Web client that connects to Codex Cloud. The CLI runs locally and is open-source and written in Rust; the IDE extension integrates into editors like Cursor and Windsurf. Codex Web delegates tasks to cloud-based sandboxed containers that run background parallel work and can be viewed on desktop, smartphone, or tablet. All variations use OpenAI models such as GPT-5 and GPT-5-Codex, while supporting other compatible providers like Ollama, Mistral AI, and Microsoft Azure. Codex adds code-specific features including GitHub integration, MCP connections, file modification, cloud delegation, and headless CI operation.
