Power your AI, scale on your terms
Start instantly with full API access and our complete model suite. Validate in the cloud, then move on-prem when you're ready - fully supported, fully yours.
Full flex with every credit
Balance = credits. Simple as that. 1 USD = 1 million credits, spendable across all models and features. No plan lock-ins, no resource silos - just total control over how and when you use your compute.
Secure payments, no surprises
All payments go through Stripe - encrypted, bank-level security, no shady stuff. No auto-renewals, no hidden charges. Just pay once and use when you want.
Unlimited time to use your credits
Prepaid = predictable. No monthly bills, no surprise charges. Top up once and take however long you need to spend your credits on any model, any endpoint.
