Effective price = official output price ÷ 2, because 2× bulk credit means every dollar buys two dollars of compute. Savings skill can reduce it further.
Somnus vs the subscription apps
Why this is cheaper
than Claude or Codex.
The Claude app and Codex / ChatGPT Plus charge a flat $20/month and cap your usage. Somnus sells you the raw model at roughly half the official price — no cap, no throttle — and a savings skill trims another ~10% off every chat.

Buy in bulk.
Pay half.
We buy large blocks of API capacity from every provider at wholesale rates, then pass the discount straight to your balance. Every top-up is doubled — pay $10, get $20 of real API spend. Your first top-up gets a 2.5× boost. Credit never expires.
2× on every top-up
Put in $10 and you get $20 of compute at the official API price — effectively half price, always.
A savings skill on top
A built-in skill routes each request to the cheapest model that still does the job, trimming another ~10% off every chat.
