Getting started
Credits and monthly plans
Credits for everything, monthly image plans for heavy image makers, how to pay, refunds and the credit calculator.
There are two ways to pay on sangtao.ai. Credits work for everything: images, video, voiceover, posting. Monthly image plans are for people who make a lot of GPT Image pictures. Prices and the packs on sale are on the Pricing page.
Credits
- Pay only for what you use. Each action costs a number of credits, listed under Price of each action on the Pricing page.
- Purchased credits never expire. They stay until you use them.
- Free credits are used first (from a monthly plan or a gift), then purchased credits.
- A failed job costs nothing. The credits are refunded automatically.
For example, each video currently has a one-time video fee: 25 credits with an AI voice (covering AI script writing, scene planning, the first 500 voice characters and 3 rebuilds), 12 credits without one. AI voices cost 40 credits per 1,000 characters, each export is at least 10 credits, and a post costs 5 credits (one post to several channels counts once). Prices can change, so check Pricing for the latest numbers.
Checking your balance
The Credits page shows four numbers:
| Item | Meaning |
|---|---|
| Available | Credits you can use right now |
| Free | Gift credits or credits from a plan |
| Purchased | Credits you bought |
| Held | Held for work still running. Spent or given back when it ends |
Below them is the Transactions list, which you can filter by Spent, Refunded, Top-up and Bonus.
Monthly image plans
Each plan gives you a quota of GPT Image pictures for a 30-day cycle. Pictures you make on the web, in bulk or through the API come out of the quota, not your credits. Other image models still use credits as usual.
- Renew and unused images carry over to the next cycle. If you stop renewing, what's left expires at the end of the cycle.
- Used up the month: on the web you keep creating without limit in the slow queue, and your images stay private. API calls have no slow queue. To get the fast lane back, renew or upgrade.
- 1K and 2K cost the same. With 1 or 20 reference images, long prompt or short, each image made counts as 1 image of your plan.
- With an image plan, AI images in Motion cost no credits.
- Besides the monthly quota there is a daily image limit that keeps the system from overloading. Normal use won't reach it.
Paying
Step 1. Pick a pack or plan
Open Pricing. Choose a Currency (VND or USD), then press Buy Now on a credit pack or Buy plan on a monthly image plan. If you aren't signed in, you'll be asked to sign in first.
The Pricing page: the "Currency" VND / USD toggle, the row of "Credit packs" cards with "Buy Now" buttons and the "Monthly image plans" section with "Buy plan" buttons
Step 2. Choose how to pay
- Vietnamese bank transfer (VND): scan the QR code with your banking app. Credits or the plan activate as soon as the payment arrives, usually within seconds to 1–2 minutes. Enter the transfer content exactly as shown. For a monthly plan, a short payment is converted to credits, and any overpayment also becomes credits.
- Card or wallet (USD): Visa, Mastercard, Apple Pay, Google Pay… Prices exclude tax, and the checkout page shows the final total. A monthly plan paid by card renews every month. You can press Cancel renewal on the Credits page at any time, and the plan keeps working until the end of the paid period.
Credit calculator
On the Pricing page, the What do you make in a month? section lets you enter how many images, 60-second videos, posts and thousand characters of voiceover you make each month. It estimates the total credits and recommends a credit pack that is just enough. If you make a lot of images, it also suggests a monthly image plan when that is cheaper.
The "What do you make in a month?" section of the Pricing page: the plus/minus steppers for images, videos, posts and voiceover, and the "Monthly estimate" box with the "Recommended pack"
Refunds
Unused credit packs can be refunded. Used packs and paid periods of a monthly plan are not refunded. The conditions and how to ask are in the Refund policy.
