What exactly is unlimited?
Generation from the Studio and the tool pages, in your browser, on the Pro and Studio plans: no credit cost, no monthly cap, nothing to top up. It is unlimited because a person is doing the generating — you look at each result and decide what comes next. Automated calls through the REST API or MCP are a different thing and are metered on their own, so a script cannot quietly turn an unlimited plan into unlimited GPU time.
Can I use the API on any plan?
Yes — every account can create an API key and call every endpoint. What differs is who pays for the generations: the Studio plan includes a monthly allowance of API generations, and calls past it keep working and spend credits like every other plan does from the first call. Mesh tools, conversions, status polls and downloads are unchanged on all plans.
What can I spend credits on?
Credits cover AI 3D model generation from text or images, every mesh tool, asset downloads and API calls. On a plan with unlimited browser generation, what you generate in Studio costs no credits at all — only automated API calls beyond the plan’s included allowance spend credits.
Do credits expire?
Pack credits never expire — pay once and spend them whenever you like. Plan credits are part of your subscription: a fresh batch arrives every month, and unused plan credits expire at the end of each billing cycle.
Can I combine a plan with credit packs?
Yes. A plan gives you a monthly baseline and packs cover the spikes — both feed the same balance. Pack credits never expire, so they stay available whatever happens to your plan.
How do I change or cancel my plan?
Any time, from the billing portal in your account. Upgrades, downgrades, cancellations and switching between monthly and yearly billing all take a couple of clicks.
Can I pay yearly instead of monthly?
Yes, on the plans that offer it. The Monthly / Yearly switch above the plans flips every price at once, and each yearly price carries what it saves against twelve monthly payments — as a number of free months where the year works out to whole ones, as a percentage otherwise. A plan with no yearly price stays on monthly billing and says so on its card.
