Public Codex usage-limit mechanics, source changes, and the boundary between a provider policy and an account-specific timer. It records what OpenAI publishes and where the account-specific answer begins.

Your remaining Codex usage is account-specific

This page cannot read your allowance or reset time. Open Codex Settings or the limit banner in your signed-in client for the options available to your plan.

The public rules worth checking

What changes how quickly the pool is used?

Task size and complexity, the selected model, and where the task runs all affect consumption. A fixed message counter would give the wrong answer.

What happens at a limit?

An active turn can continue subject to fair-use limits. Afterward, the available account options can include credits, a reset, an upgrade, or waiting for the limit to reset.

ChatGPT plans, prices and what the same money buys on the API

Prices and included usage are copied from OpenAI's pages with the date we read them. The provider publishes multiples and message estimates, not a token or dollar cap, so the rows keep the provider's wording and no cap is invented.

What the Plus price buys at API list rates: $20 is 10 million input tokens or 1.7 million output tokens of GPT-5.6 Terra ($2 and $12 per million, registry updated September 25, 2026). Arithmetic on published rates, not a statement of the plan's allowance; past the plan's own limit, extra usage is what the provider's page says it is.

Plan price beside the API list cost of a workload

Pick a plan, a Claude model and a workload. The API side is list rates times the tokens you enter, the same arithmetic as the pricing calculator. The plan side is its published price; its cap is not published.

Does the plan cover it?
Unavailable
The plan does not publish its included usage in credits or dollars; no equivalent can be computed. At this workload the API bill is above the plan price; past the plan's cap, extra usage is billed at the same API rates.

Keep these assumptions with the decision. The estimate above is today’s list rates against the workload you typed; both move. Save it as a Radar cost scenario and the next review starts from the same numbers, with the source of every rate attached.

Estimate only, at list rates from the pricing registry. It excludes reasoning tokens billed as output, batch discounts, taxes and provider minimums. Confirm the exact model identifier in the model ID directory and the rate on the Claude API pricing hub.

A published reset rule is not your reset clock

Product limits can depend on plan, location, workspace controls, prior use, feature availability, and the exact work requested. A useful public page preserves that distinction rather than turning a provider article into a fake personal dashboard.

Radar watches

  • Published changes to plans, usage mechanics, reset rules, and model availability.
  • Public Codex release and documentation changes with the original source attached.

Radar does not read

  • Your remaining allowance, private reset timer, threads, prompts, or account bill.
  • A promise that a public policy change changes every account at the same time.
