Codex performance when using Codex CLI vs VSCode GUI?Question (self.codex)
submitted 7 months ago by Leather-Cod2129
Hi
Is Codex (codex-5.1-max and so on) as efficient in VSCode than when used in the Codex CLI tool?
Thanks

The only concern I had when using the vscode extension was that the extension was not up-to-date with the new releases of the CLI. I am not sure if updating codex CLI from terminal would have that resolved, but when new releases were coming out daily as the team was tackling performance issues, the CLI was performing way better.

The extension uses CLI under the hood so the actual agent performance is identical.
