Our verdict
If you already pay for ChatGPT, try Codex first: it costs nothing extra and works in your current editor. Pick Cursor if you want an AI-native editor experience and are fine paying for it, keeping in mind that third-party models (including OpenAI's) are billed at API prices on Cursor Premium and above.
