About Somnus.
Somnus is an open-source-based desktop AI agent plus a model gateway, so one account and one balance reach 50+ models.
Payments are processed by Stripe. See the model price table for official list rates and the effective rate after doubled credit.
Pay as you go: top up from $5. Every top-up is doubled, and larger top-ups receive a bigger bonus.
Dreamcaster Enterprise: for teams and heavy users — custom volume pricing, shared team budgets, priority support and invoicing. Talk to us at somnus.world/enterprise.
Questions
How do I get the free credit?
Create an account, confirm your email, then verify and save a credit or debit card with Stripe in Billing to unlock $10 free API credit. No charge, subscription, or automatic top-ups. Your bank may show a temporary verification hold. The offer is one-time per new account and card; existing promo offers keep their original terms.
Do bigger top-ups get more?
Yes. Every top-up is doubled, and larger ones get a bonus on top: 2.2× from $50, 2.35× from $100 and 2.5× from $200.
How is it cheaper?
Every paid top-up is credited at 2× or more, so each dollar you pay buys at least two dollars of usage at our listed model rates.
Which models can I use?
Claude, GPT, Gemini, Grok, DeepSeek, Qwen, Kimi, GLM and more. The catalogue updates from the gateway.
Can I use it from my terminal?
Yes. Your Somnus key works with OpenAI-compatible tools and scripts using the Somnus gateway URL.
Which platforms?
Windows and Linux now. Mac is on the way.
How do I sign in to the app?
Click sign in in the app, your browser opens somnus.world, and the app connects itself. No codes to copy.
Is there a subscription?
No subscription is required. Top up when you want and your prepaid credit does not expire.
