razorBridge AI Blades
GPUs by the hour, SSH-ready.
Pick a GPU, see its price and billing minimum, and SSH in. Usually ready in a few minutes. Self-serve runs on a prepaid balance; universities and contracts pay by invoice.
From €1,09/h excl. VAT, 60-min minimum
How it works
Pick a GPU. See the price. SSH in.
Usually ready in a few minutes. Auto-stop means a forgotten GPU stops billing, and the Hub tells you how long your balance lasts before you launch.
- Billed per second after a 60-minute minimum, excl. VAT.
- A plain SSH host: scp, rsync and VS Code Remote work.
- Multi-GPU classes are on the pricing page.

Large model training
Drawn from the Hub's launch view. Prices are live; the layout is illustrative.
Each GPU is a plain host: ssh, scp, rsync and VS Code Remote work.
Every GPU shows its hourly price and its billing minimum in the Hub before you launch it.
A forgotten GPU stops billing. Labs and events stop at their end time.
Set how many students share a GPU, from one each to 20, per lab.
Events, credits and the AI Gateway are also available through the REST API.

The Hub
This is the product, not a mock-up.
The razorBridge Hub is where you launch AI Blades, plan labs and events, and create API keys. Every GPU shows its price and its billing minimum before you start it.

Events and labs
A GPU lab for your class, in one link.
For courses, workshops and hackathons, built on AI Blades. You plan it, students join, and it cleans up after itself.

Questions
Straight answers.

How does billing work?
Self-serve accounts use a prepaid balance. Each GPU bills at least 60 minutes, then per second, and AI models bill per million tokens. Universities and contracts pay by invoice. You see the price before every start.
Where do the GPUs run?
In EU data centres only, operated by EU-headquartered cloud providers.
What happens when a lab or event ends?
Its GPUs stop at the end time, and billing stops with them.
What happens when credits run out?
We email you when your balance falls below about an hour of runtime. When it runs out, a self-serve session stops automatically, and anything not saved off the blade is lost. To keep going, email us and we add credit to your balance.
