razorBridge — compute
razorBridge is KlusAI’s compute product. You rent GPU capacity as razorBridge AI Blades, work on them over SSH, and pay from a prepaid credit balance in euros. The same balance also pays for razorBridge AI Gateway — an OpenAI-compatible model API you can point an application at.
razorBridge is the developer-facing product in the family: you start sessions, run events and manage inference keys in the web app, and everything else goes through the REST API. It is built on kOS, the platform shared with Lex and Med.
Two ways to get a GPU
Section titled “Two ways to get a GPU”- Self-serve sessions — you start a blade for yourself, pick a duration, and it stops automatically when the time is up. Billed to your own credits.
- Events — an organizer schedules a workshop, lab or competition; blades are provisioned before the start time and torn down at the end. Participants join with a code and never see a bill; the organizer’s account pays.

Live product surfaces
Section titled “Live product surfaces”Current GPU availability, published hourly rates and the cost calculator are on
razorbridge.eu — rates are read from the live pricing
catalogue, so that page (or GET /v1/gpu-types/) is always the authority. This
documentation deliberately does not repeat euro rates.
