The reservation
A run reserves its worst case before it starts, so no run starts that could not be paid for. A long generation can briefly look more expensive than it turns out to be.
Pricing
A price, and the model spend it includes
Model spend is what costs money to run, so each plan includes some every month.
Free
$0no subscription
$0.20 to try it without a card
$1.00 of model spend included each month once a card is saved
An account with no active subscription is Free. It builds with GPT-6 Luna and keeps up to three active projects.
Build
$19a month
or $190 a year, two months free
$14.00 of model spend included each month
Upgrading starts a Stripe Checkout session. Cancel plan is in the builder’s settings menu; cards and invoices are in Stripe’s billing portal.
Ship
$49a month

$40.00 of model spend included each month
Upgrading starts a Stripe Checkout session. Cancel plan is in the builder’s settings menu; cards and invoices are in Stripe’s billing portal.
Prices are in US dollars and are charged through Stripe Checkout, which shows the total before anything is charged. Nothing is charged automatically past the allowance unless you turn it on: auto-reload buys a $10 top-up on your saved card when less than $1 is left, up to a monthly cap you choose, and Start Build moves a Free account to Build once when less than $1 is left. A build you cannot fully fund is started smaller rather than refused, and once too little is left for even that, runs are refused until the month resets or you buy a top-up.
- New accounts
- A Free account without a card has $0.20 of model spend once, to try it. Saving a card (saved, not charged) starts the Free plan’s monthly allowance, once per card.
- Resets
- On the UTC calendar month, for everyone.
- Top-ups
- $10 adds $8.00 of model spend, on any plan, used only once the allowance is gone. It expires twelve months after purchase.
- Event pass
- $49 one time, for one site: 12 months on your own domain, private if you want it, with $8.00 of model spend and no subscription. It does not count toward the Free plan’s 3 active projects.
- Per run
- Reserves its worst case up front, then you are charged what it actually cost.
How a run is priced
Reserved up front, charged for what it cost
The reconciliation
When the run finishes it is reconciled to what it actually cost, and that is what you are charged. Prices follow the model that runs: a cheaper model reserves less and costs less.
The order things are spent in
Three ceilings, in this order
When a run is refused for spend, the reason names which ceiling it hit and, for your own, how much is left against how much the run needs.
A deployment-wide daily ceiling
Across all accounts, so that one compromised account cannot spend the month. Invisible in normal use. Free runs also share their own part of it, so free use takes at most that part and the rest stays for paying accounts; runs paid from top-up credit do not count as free use.
Your monthly plan allowance
It resets on the UTC calendar month for everyone, rather than on each subscription’s anniversary: easier to reason about, at the cost of a first month shorter than thirty days.
Your top-up credit
Tried whenever what is left of the allowance cannot hold a run’s reservation, and a run is drawn from one or the other, never both. Top-ups are one-time purchases on any plan, Free included, and expire twelve months after purchase.
Changing or canceling
Stripe handles the money
Upgrading
Starts a Stripe Checkout session. Plan and usage in the settings menu is a read-only mirror of the figures the spend gate uses.
Billing and cancellation
Once you have a Stripe customer record, Manage billing opens Stripe’s own billing portal, where cards and invoices live. Cancel plan, beside it, offers a monthly plan 50% off one month, once, before it cancels; a yearly plan is offered nothing. Refunds are covered by the Refund Policy.
