The short answer
OpenAI Codex is a coding agent that comes with ChatGPT: you give it a task in the terminal, your editor, the desktop app or the cloud, and it edits code, runs commands and opens pull requests using OpenAI models. Cursor is an AI code editor with its own agent, Tab completions, cloud agents and Bugbot code review, where Grok models are included and models from other labs are billed at API price. Pick Codex if you pay for ChatGPT and want to delegate tasks. Pick Cursor if you want AI built into the editor you type in every day. Facts are as of November 2026.

The differences that matter
Delegation vs pair programming. Codex is built for handing off: write the task, let it work in a sandbox locally or in Codex Cloud, review the diff or pull request. Cursor is built for working alongside the AI in the editor, with completions as you type and an agent you can stop and steer. Cursor's cloud agents and Codex's IDE extension narrow the gap, but the default habit is different.
What your money buys. ChatGPT Plus at $20 gets you Codex plus everything else in ChatGPT (chat, deep research, images, voice). OpenAI estimates Plus usage per model: for example 15 to 160 local Codex messages per five hours with GPT-6.1 Sol. Cursor Premium at $30 gets you 4x the Plus pool for Grok models, cloud agents and Bugbot, but GPT or Claude usage is billed on top at API price. If you mostly want OpenAI models, Codex is the cheaper path.
Openness. You can read, fork and script the Codex CLI (Apache-2.0) and run it in CI with an API key, though API-key mode has no cloud features. Cursor is closed source.
Use them together. The Codex extension runs inside Cursor. A common setup is Cursor for editing and Tab, and Codex (on a ChatGPT plan you already have) for longer agent tasks, so you are not paying Cursor's per-token rate for GPT.
Which to pick
- You already pay for ChatGPT Plus or Pro: Codex, at no extra cost.
- You want completions while you type: Cursor.
- You want to try for $8: both have one: ChatGPT Go (Codex in the desktop app) or Cursor Plus (Grok models).
- You need an open-source agent: the Codex CLI.
- You want AI review on every pull request: both do it; Codex from Plus, Cursor's Bugbot from Premium.
