The reservation
A run reserves its worst case before it starts, which is what stops a run starting that could not have been paid for. That is why 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 actually costs money to run, so each plan comes with an amount of it every month. An account with no active subscription is Free.

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: once it and any top-up credit are spent, runs are refused until the month resets or you buy a top-up. vibld is invite-only for now.
- New accounts
- Granted $1.00 once, separate from the monthly allowance.
- Resets
- On the UTC calendar month, for everyone.
- Top-ups
- $20 adds $8.00 of model spend, on any plan, used only once the allowance is gone. It expires twelve months after purchase.
- 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, which is the practical reason the model selector exists.
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.
A deployment-wide daily ceiling
Across all accounts, so that one compromised account cannot spend the month. Invisible in normal 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 only once the allowance is genuinely exhausted, not merely low. Top-ups are one-time purchases on any plan, Free included, and expire twelve months after purchase.
Changing or cancelling
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, invoices and cancellation live. Refunds are covered by the Refund Policy.
