FAQ
Do I need a credit card?
No. Sign in to YingTu with your Gmail account and the credit is issued to your browser automatically.
Which accounts qualify?
Only Google accounts ending in @gmail.com. Work or custom-domain Google accounts can sign in, but they do not receive the free credit.
How many images does $0.1 cover?
It depends on the model: about 5 with Seedream 5.0 Flash, 4 with Nano Banana 2 Lite, 3 with GPT Image 2 VIP or GPT Image 2.5, and 1 with Nano Banana 2 or Nano Banana Pro. Nano Banana 2.1, the studio's default model ($0.045), gives about 2.
Can I use Nano Banana Pro for free?
Yes, for one image: Nano Banana Pro costs $0.09, so the $0.1 credit covers about 1. Nano Banana 2.1 gets you about 2 images and Seedream 5.0 Flash about 5. After that you pay per image with your own laozhang.ai key.
Can I try GPT Image 2 for free without ChatGPT Plus?
Yes. The credit covers about 3 GPT Image 2 images (GPT Image 2 VIP, $0.03 each) with no ChatGPT Plus subscription and no card. After that, each image costs $0.03 from your LaoZhang balance.
Can I use it for layer decomposition or video?
Plain Seedream 5.0 Flash generation is covered. Layer decomposition returns 6–17 images per run (about $0.1–0.3), more than the credit, so it is not. Seedance 2.0 / 2.5 and Wan 2.7 video also need your own key from laozhang.ai and are billed by usage.
What happens when it runs out?
Sign up at laozhang.ai for another $0.1, paste the new key into YingTu under “API Key”, and top up on laozhang.ai when you need more (cards through Stripe, or USDT).
Is my key safe?
Your key stays in your browser and goes straight to the LaoZhang API when you generate. YingTu servers do not store it, and the grant endpoint never exposes any management credentials.
Can I use it on another computer?
Yes. Sign in with the same Google account and you get the same free key back, as long as it still has balance and has not expired.
