How billing works
No per-request fees — you pay for the tokens the AI actually consumes
Credits scale with the work
How many credits a task spends depends on the model it runs on and how much work it takes — input, output and reasoning depth. Quick tasks on lighter models barely cost a thing; deep, complex work on top-tier models costs more. Cache-hit turns are naturally cheaper.
Daily quota + credit fallback
Every model tier included in your plan has a free daily token quota that resets each day; credits are only tapped once the day's quota is used up. Quotas don't roll over.
Free credits on signup
New users automatically get 500 credits — no card needed. Enough to build your first app on us.
Visitors aren't on your tab
When other people use your published apps, their AI usage draws from the platform's public pool — not from your balance.
In one sentence
Monthly credits are a cross-tier fallback allowance: the system only deducts credits after a model tier's free daily tokens run out. Light daily use barely touches credits — heavy use or top-tier models are what consume them.
FAQ
What is the founding member plan?
Subscribe to Pro before October 10 and you keep the founding price: $4.99 for your first month, then $9.99/mo ($99 billed yearly). As long as your subscription stays active the price never changes — later price increases won't touch you. After the deadline, Pro is $14.99/mo.
Can I try Yuan without signing up?
Yes — every published app in the gallery is open to visitors: open one in your browser and use it right away, no account needed. Building your own app takes a free account (no credit card), which comes with free credits.
Do credits expire?
Monthly credits refresh with your billing cycle and don't roll over; the signup grant is a one-time gift.
What happens when I run out?
When the day's token quota is used up, the system automatically falls back to your monthly credits; once those run out too, builds and AI calls pause — upgrade anytime, or wait for your 24-hour quota window to refresh.
What are model tiers?
Three tiers — basic / advanced / pro — and you pick one when building. Higher tiers reason better and cost more per token. The pro tier is a paid-plan feature; the free plan includes a daily basic-tier token grant, and the advanced tier can be used with credits.
Can I cancel anytime?
Yes. After cancelling you keep access until the end of the current billing period, then drop back to the free plan automatically.
