How do I provide the API key to Codex in VS code though? With Codex CLI I set the OPENAI_API_KEY variable, but what do I do with here? Also my vscode runs on Windows and remotely connects to Linux. I created .codex/config.toml on Linux but I guess I also need to create auth.json? What’s the syntax? …

I have a request: can you make previous chats available in codex VS Code extension? If I restart VS Code all local chats disappear.

I think they are talking about using Codex with the API. I am not using an API to access codex, I am using my regular subscription.

The extension is not loading in VS Code on Windows 11 after installing it.

We just switched to github copilot because this wasn’t supported in codex. Good improvement to be made, will definitely keep a close eye on this. Developers empowered to not have to open a browser is a major plus one for us.

Is there a setting we can use to preserve local chat history, perhaps writing to a local log file? As it currently stands, local history disappears on VSCode reload/restart and all I’m left with is my commit history which lacks the rationale for the PR.

+1 on this. Preserving the local chat history on reload. Also wpuld be awesome if this is optionally synced with the cloud version.

Why is this still bugged with how fast u can code with codex in vscode??? Use your own product and fix the bugs, PLEASE
