How a CodexUZ plan works: the limit, the week and the referral code

CodexUZ is a service that gives access to OpenAI's GPT coding models through Codex CLI, VS Code or an API, paid for in Uzbek soums. Its plans are not like an ordinary subscription: you are buying a usage limit, not a period. People who miss that difference end up wondering where the limit “went” and why the discount did not apply.

There is currently 1 active offer on the CodexUZ page.

The limit is credit, not money

Each plan gives a limit expressed in US dollars for a set period. The service's terms say it outright: the limit is credit for AI usage, not a cash balance. It cannot be withdrawn or moved to another account.

Usage is counted per request, in tokens: input, cached input and output tokens are counted separately. According to the service, it bills at the model provider's official rates. The console shows the model, the tokens and the cost of every request, so there is no need to guess where the limit went.

Two caps: weekly and total

The thirty-day plans have two caps, not one.

The weekly limit. The most you can spend in a seven-day window. It renews on a schedule.
The total limit. Spending over the life of the plan cannot exceed it.

The rule people miss most often: an unused weekly limit does not carry over to the next week. Take a week off and that week's limit is gone. So it makes sense to line a plan up with the start of a project rather than buy it just before a holiday.

The one-day plan is simpler: it has a single limit, and that limit lasts one day.

How the choice of model eats the limit

Models are not priced alike: a million tokens of a flagship model cost several times what an economy model charges. On some models a request with a very long context is billed at a higher rate too. So how much gets done on the same limit depends on which model you pick.

The model is changed with one line in the settings file. Giving simple tasks to a cheaper model and hard ones to a stronger one makes the limit last longer. The request log in the console shows what each task cost.

Where the referral code goes

A CodexUZ referral code goes in at sign-up, not at payment: the form has an optional “Referral code” field. Arrive through a referral link and the field is already filled in.

The code gives a discount on a first plan purchase, and that discount lasts a limited time. Payment, meanwhile, is taken by hand, so it helps to know the order in advance:

Sign up and confirm your email.
Pick a plan on the pricing page.
Message the service's admin on Telegram and confirm the discounted amount.
Send the money by bank transfer and show the receipt.
Once it is confirmed, enter the one-time activation code in the console.

An activation code binds to the first account that enters it and will not work a second time, so do not pass it on to anyone.

What to know before you pay

No refunds. Once a plan is activated the limit opens at once, and the unused part is not refunded. If a payment went out by mistake or twice, you have to write to support.
Activation is not instant. An operator checks the transfer, so expect a short wait.
Nothing renews by itself. When a plan ends, no money is taken automatically; a new package bought on top of an active plan starts when the current one ends.
The key is shown once. The full API key is visible only at the moment it is created; if it is lost, the console replaces it with a new one.
No guarantee. The service does not promise uninterrupted operation for now, and the models' availability depends on the provider.

What happens to your code and requests

Under the terms, all rights to your code and requests stay with you, and the service does not use them to train models. The ordinary usage log keeps the request identifier, the model, the token counts, the cost, the latency and the status. If a request fails, support asks for the request identifier from the console rather than your source code.

The rule about the API key belongs here as well: the terms forbid handing the key to someone else or reselling the limit, and a key that may have leaked should be replaced straight away.

Who it suits

This kind of plan suits someone who codes steadily every day: the weekly limit is built for exactly that rhythm. For people who code once or twice a month but in large volumes, the weekly cap can get in the way, because a limit left unspent in one week is not added to the next. In that case the one-day plan or an extra usage package fits better; the extra package is sold only alongside an active plan.

On PromoBozor, the CodexUZ page shows the referral code, its terms and the date it was last checked. Look there for the size of the discount and how long it lasts before you use the code.

Frequently asked questions

What do I do when the weekly limit runs out?

There are three ways out. The first is to wait for the limit to renew on its schedule. The second is to buy an extra usage package: it is sold separately and can only be added to an active plan. The third is to move to a higher plan. Bear in mind that a week's unused limit does not carry over, so saving a big job up for one week gains you nothing.

Can I enter the referral code after I have signed up?

The site says nothing about that. The code field sits in the sign-up form and is optional, so it is very easy to skip. The reliable route is to arrive through a referral link, which fills the field in for you. Before you create the account, check that the code is in the field, because the discount applies only to a first plan purchase and lasts a limited time.

When does a plan start after I pay?

Not straight away. Payment is a manual bank transfer: an operator checks the transfer and, once it is confirmed, gives you a one-time activation code. When you enter it in the console the plan becomes active and an API key is prepared. The discount window is short, so agree the discounted amount with the admin before you transfer anything, and keep the payment receipt.
