How much does Codex cost?

Codex is billed as a flat subscription, so 'how much does it cost' has two honest answers.

What you actually pay

Codex comes with a ChatGPT plan — $20/mo on Plus, $200/mo on Pro — and your usage is metered against a rate-limit pool, not per token. That subscription price is your real cost.

The notional list price

It can still be useful to know what your Codex usage would cost at OpenAI's API rates. JP the Cat computes that as a clearly-labelled notional figure — never presented as real spend, because on a subscription you did not pay per token.

Common questions

Does Codex charge per token?: Not on a ChatGPT subscription — it meters usage against a pool. A per-token figure is notional list price, not a bill.
