OpenAI Codex Now Available in Zed Code Editor via Agent Client Protocol
By

A baker's-dozen of insight crammed into one ring.
Summary
Zed has integrated OpenAI's Codex AI agent into its code editor through the Agent Client Protocol (ACP), making it available out-of-the-box for users. This integration allows developers to access Codex directly from the New Thread menu alongside other AI assistants like Claude Code and Gemini CLI. The implementation focuses on improving user interface and maintaining workflow within the IDE, while billing and terms remain directly between users and OpenAI, with Zed not charging for the external agent usage.
Key quotes
· 3 pulledWhen we introduced the Agent Client Protocol (ACP) in collaboration with Google's Gemini CLI team, we did not anticipate how much pent-up demand there was for a protocol like this!
As of today, Zed supports Codex out-the-box via ACP. You can select it from the New Thread menu, just like Claude Code or Gemini CLI.
Like our other ACP integrations, Codex via ACP is strictly about improving UI and keeping you in flow in your IDE of choice; the billing and legal/terms arrangement is directly between you and OpenAI.
