Costs are shown before consequential work, and a run reserves its units before it starts. If a run is cancelled, unused units are released. When you reach your allowance, new runs stop with a clear message and your existing work stays readable.

Billing questions

Why is pricing labelled as a pilot?
Plans and dollar figures are experiments while we measure what runs actually cost. Billing runs in Stripe test mode, so no real charges are made, and prices may change before launch.
What is a usage unit?
Roughly one bounded agent or execution step. Each kind of work has a fixed unit cost, shown in the table, and the cost is reserved before the work starts.
What happens if a run is cancelled or fails?
Cancelling stops the work and releases the units that weren’t used. Failed results are kept with the run so you can see what happened.
What happens when I reach my allowance?
New runs stop with a clear message that says what limit was reached. Your existing projects, releases and evidence stay readable.
Do reviewers need a seat?
No. Reviewers can comment and approve on every plan without a paid seat. Editors are the people who change systems and screens.
