1 credit per training step, plus 1,000 per model in the blend. A normal two-amp blend (12,000 steps) is 14,000 credits. Unused steps come back when you stop a run early, and failed runs cost nothing. Credits don't expire.

Payments are handled by Lemon Squeezy, our reseller: cards, PayPal, Apple Pay and Google Pay. See the refund policy. A refund takes back the credits it paid for.
