I have already installed the latest version of VS Code Insiders and the extension Codex - OpenAI's coding agent, but I still cannot see OpenAI Codex in the Chat Session. Is there any other setting I need to do?

Hey doggy8088,

I’ve already installed the latest version of VS Code Insiders and the Codex – OpenAI’s Coding Agent extension. However, I still cannot see OpenAI Codex appear in the Chat Session inside VS Code.

Could you please let me know if there’s any additional setup, account linking, or configuration required to enable Codex in the chat?
I’ve restarted VS Code and reinstalled the extension, but it still doesn’t show up.

Thanks in advance!

That is the question I asked. 😅

you won’t see OpenAI Codex in the chat session list unless it’s properly registered as a chat participant inside VS Code’s agent system. just installing the codex extension doesn’t automatically add it there.

open the command palette (ctrl+shift+p) then
> Generate Agent Instructions
this sets up the Codex agent so VS Code knows how to talk to it. once that’s done, reload the window ctrl+shift+p then Developer Reload Window.

after reload, you should see OpenAI Codex ya Codex Agent appear in the chat panel under local chat sessions.if it still doesn’t, check the Output panel view then output then select Copilot or Codex for any startup errors.

in short install the extension, run generate agent instructions, and reload. that usually fixes it.

After I update my VS Code Insiders 4 times for today, all issues are resolved.
