How is ECU charged?

Per compute-intensive operation (model inference, judge calls, GEPA, trace evaluations). See ECU concept.

When does ECU expire?

Free tier starter ECU expires per the terms; PAYG ECU does not expire while your account is active.

Where do I see invoices?

Settings → Billing → Invoices.

Can I upgrade or downgrade?

Yes. Free → Premium PAYG is self-serve. Premium → Enterprise is sales-led.

What if I run out of ECU?

New compute-intensive operations are blocked until you top up. Catalog browsing and saved configs continue to work.
