How Credits Work
Understanding VULK credits, how they are consumed, and how the cost scales with your plan.
How Credits Work
Credits are the currency you use to generate and edit projects in VULK. The same project costs different credits on different plans because each tier defaults to a different model class. Free runs on Gemini 3.1 Flash Lite — a fast model great for quick iterations — so credits stretch further. Paid plans default to flagship models (Gemini 3.1 Pro, Claude Sonnet 4.6, GPT-5.5) which produce higher-fidelity output and richer reasoning at a higher per-credit footprint.
Credit Costs (per plan)
| Tier | Free (Flash Lite) | Builder | Pro / Max |
|---|---|---|---|
| Simple (landing page, single component) | 5 | 15 | 25-35 |
| Medium (dashboard, multi-page site) | 15 | 35 | 60-90 |
| Complex (full-stack app with backend) | 25 | 80 | 150-250 |
| Edit (chat refinement on existing project) | 1-3 | 5-10 | 10-20 |
These are typical ranges — the exact cost depends on the size of the prompt, the number of files generated, and how many tool calls the AI needs to finish. Image generation is a separate line item on paid plans and runs at roughly 1 credit per image.
Credit Renewal
- Free plan: 100 credits reset on the 1st of every month. No card, no time limit on the account itself.
- Paid plans: Credits reset on your billing date each month.
- Credits do NOT roll over — unused credits expire at renewal.
Checking Your Balance
Your credit balance is shown in the top-right corner of the dashboard.
Running Low?
- Buy a credit pack (one-time purchase, see Plans Overview).
- Upgrade your plan for more monthly credits + access to image / video generation on Builder+ / Pro+.
- Wait for renewal if you're not in a hurry.
FAQ
Do unused credits carry over? No. Credits reset each billing cycle.
Can I buy extra credits without upgrading? Yes — credit packs from 1,000 to 10,000 credits are available as one-time purchases. See Plans Overview.
Why do some projects cost more? Complex projects with more features, pages, or backend requirements use more AI processing. The same project also costs more on paid plans because they default to higher-quality (more expensive) models — that's by design and reflects in the per-tier pricing above.
