Codex is Live in Zed — Zed's Blog

Zed now supports OpenAI's Codex AI agent through the Agent Client Protocol (ACP), joining previously integrated agents like Claude Code and Gemini CLI. The integration is open-sourced and maintains direct billing between users and OpenAI, with no data passing through Zed's servers. The team shares technical insights about handling different agent implementations, particularly around terminal command execution and PTY mode differences. With growing ACP adoption across editors like Neovim, Emacs, and JetBrains IDEs, Zed is shifting focus from building adapters to supporting community-driven protocol development.
