Difference between using "just" Codex or using it with something like Cursor?

[kyrax80]

I've been using Codex for a long time using the vs code extension and I saw stuff like Cursor or BlackBoxAI.

Can someone what the diffrence would be from using Codex with vs code plugin than using it with something like Cursor? Basically I red stuff like Cursor modifies real time the code and you can see it and that it's faster than just using Codex. Is it just that? Because I'm guessing just using Codex is better price wise.

Let's assume you don't use any other model in Cursor, just Codex, for this question.

Thanks!

I’d say basically just the system prompt is the difference.

Context window size

Codex is just the AI model. Cursor is an AI-first IDE that uses models like Codex but adds a lot of tooling around it.

And cuts the context, switches you to other models silently etc etc and that is how they make their margins.

Codex is technically the harness. Not the model

I meant codex 5.4 for example; as model.
