How to Check Codex Usage in ChatGPT (Plus, Pro and Credits)

TL;DR: ChatGPT’s Codex has its own usage analytics page at https://chatgpt.com/codex/cloud/settings/analytics, separate from the main ChatGPT settings. You need to be logged into your ChatGPT account first. The page splits your Codex usage into three meters: a 5-hour rolling limit, a weekly limit, and pay-as-you-go credits. Here is an example screenshot:

Where EXACTLY Do I Find My Codex Usage on ChatGPT?

You have to be logged into your ChatGPT account first. Then paste this URL into your browser:

https://chatgpt.com/codex/cloud/settings/analytics

Two things worth knowing before you go looking for it:

1. This page is not under the main ChatGPT Settings menu. It is on the Codex side of ChatGPT, which is a separate area of the product.
2. The fastest way to land here when you are locked out is to click the red “Usage limit reached” pill in the Codex header. ChatGPT routes you straight to the analytics page.

If you work mostly in the terminal, the Codex CLI can pin these meters to a status line so you never have to open the analytics page. Here is my Codex CLI status line walkthrough.

What Are the Three Meters?

Three independent budgets are tracked on this page:

5-hour usage limit. This is the one most people hit first. Rolling window. Local Codex messages and cloud tasks both draw from it. The page shows the reset timing for your current window.

Weekly usage limit. Separate cap on top of the 5-hour. You can hit your 5-hour wall and still have 80%+ of your weekly intact, which is exactly what my screenshot shows.

Credits. Top-up that kicks in after you hit included Codex usage limits. Codex credit pricing has been token-based since April 2026. Plus and Pro users can buy them and the balance feeds back into the same Codex pool. Since June the Codex CLI /usage command also surfaces any earned limit-reset credits, and since July 9 it shows each credit’s type and expiration and lets you choose which one to redeem. Banked resets lapse 30 days after they are credited.

The card right on the analytics page reads: “Codex usage draws from your shared agentic usage limit.” That means Codex, ChatGPT for Excel, and other agentic features all draw from the same bucket. Heavy Codex use eats into whatever else agentic ships on your plan.

How Many Codex Messages Does ChatGPT Plus Actually Give Me?

Per OpenAI’s official Codex pricing page, here is the July 2026 rate card for the $20/month Plus tier after the GPT-5.6 rollout, per 5-hour window:

Model	Local messages per 5-hour window
GPT-5.6 Sol	15 to 90
GPT-5.6 Terra	20 to 110
GPT-5.6 Luna	50 to 280

The range is wide because consumption varies by message size. A 50-line diff review costs more than a one-sentence question. Long prompts, attached files, and large code reviews burn faster than chat-style turns.

Is Upgrading to Pro Worth It?

For Plus users hitting the wall regularly, here is the math, again from OpenAI’s pricing page:

Tier	Price	Sol	Terra	Luna
Plus	$20/mo	15 to 90	20 to 110	50 to 280
Pro 5x	$100/mo	75 to 450	not published	250 to 1,400
Pro 20x	$200/mo	not published	400 to 2,200	1,000 to 5,600

OpenAI only publishes some of those per-model ranges and leaves a couple of cells blank. Where the table says not published, that is OpenAI not saying, not me guessing.

If you read an earlier version of this post, the temporary Pro promos are gone. The Pro 2x promo expired May 31, so the $100 tier is back to the standard 5x and the $200 tier is back to 20x on the 5-hour window. A separate June referral promo ended June 24, and as of July 2026 nothing has replaced them. The bigger July change is GPT-5.6 (Sol, Terra, and Luna) landing on July 9, which is why the rate card now lists limits per model.

If you blow through Plus more than once a week, Pro 5x is the obvious step. If you hit the wall once a month and can wait 5 hours, stay on Plus and treat the lockouts as forced breaks.

What Do I Do When I Hit 0% on my 5 hour block?

Three options when the 5-hour allotment is used:

1. ⏰ Wait it out. The 5-hour window rolls forward whether you are paying attention or not. For occasional Codex users this is fine.
2. 💰 Buy credits. Pay-as-you-go top-up at token-based rates. Useful for “I just need to finish this one task” moments. Earned reset credits can also be redeemed straight from the Codex CLI with /usage.
3. 💰💰 Upgrade to Pro. 5x quota for $100/mo

If you are locked out and the task can wait, option one is the cheapest. Maybe just take a nice break and have a phone alarm for your reset time, come back when the meter ticks over.

The End

I hope this helps! I try to keep this info updated but OpenAI frequently changes things, so if something looks amiss just let me know. Also, if you have questions, tips or tricks to share, feel free to comment. Thanks for visiting! 👍👍
