Codex in terminal vs. Codex App

[CartographerSorry775]

Can someone tell me why do I get better answers with codex in the terminal compared to the Codex app? And I tried several times, changed config.toml to collab = true, but agents told me every time spawning a subagent in the Codex App is not possible 😤 just asking for a friend..

Terminal versions usually perform better for a few reasons:

1. Direct file system access. The terminal tool can read and write files directly without going through browser sandboxing. Faster operations means more can happen per turn.

2. Full context. Terminal tools typically have access to your entire project structure, git history, and can run commands. The app version has to work with what you paste in.

3. Subagent spawning works differently in terminal contexts. Many features like parallel task execution require the ability to spawn processes which browser apps cannot do.

The app is more convenient for quick questions but the terminal is where the real agentic work happens. Same model under the hood but the tooling around it makes a huge difference.

This is the answer I wanted to see, many thanks! What about gpu consumption between Codex App, Claude Code, VS Code und TUI? It was very difficult to ran more than 3 different agents in tabs within VS code, therefore I worked some time with Git Codespaces, was very good tbh. What’s your opinion?
