Codex is working to be OpenAI’s cloud coding agent that takes software work from a prompt through an isolated sandbox to a pull request, accessible from the CLI, IDE, and ChatGPT. It holds a dominant, rising footprint in coding-agent and GTM developer-tool conversation. Its profile centers on agents that can carry out bounded development tasks rather than only assist inside an editor. The API, MCP, SDK, and CLI surfaces put Codex in the operating stack for developers building and running those workflows.

Business Profile
Codex sits within OpenAI's software development business, with distribution through ChatGPT and developer tools. The cloud coding agent launched in May 2025, and the product now spans an app, CLI and IDE extension, with an open-source agent framework developers can embed in their own workflows. Parent company OpenAI announced a $110B funding round on February 27, 2026, backed by Amazon, SoftBank and NVIDIA. That financing belongs to OpenAI; Codex operates as a product within the parent company's broader model and infrastructure investment.

Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
Codex is built to run from several places: the CLI, the IDE, and ChatGPT, each handing a prompt to the same cloud agent that returns a pull request. Its CLI is public on GitHub. Docs for its API, MCP and SDK surfaces are not on file yet, so this memo covers the CLI only.
