Models are grouped by where they run. EU-only models run in Paris with an EU-headquartered provider and fail closed, with no fallback outside the EU. Every other model says so and names its provider.

  • Input and output price per million tokens on every model.
  • Self-serve keys draw on the same prepaid balance as your AI Blades.

From €1,09/h excl. VAT, 60-min minimum

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.

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.

The razorBridge Hub GPUs page: a card per GPU class with its hourly price and billing minimum, and a Launch button.

Built for

Built for the way you buy compute.

Five kinds of buyer, five different first steps.

Price, speed and an API you already know.

  • An OpenAI-compatible endpoint: swap the base URL.
  • Prices on the page, before you start.
  • SSH, scp, VS Code Remote: a GPU is a plain host.

A GPU lab for your class, paid by invoice.

  • Students join with a link or QR code. They never enter a card.
  • Pay by pro-forma or invoice from KlusAI Labs SRL.
  • The lab tears itself down at the end time.

Questions

Straight answers.

Something else? Talk to us.

Which AI models stay in the EU?

The ones labelled EU-only. They run in Paris with an EU-headquartered provider and fail closed rather than fall back outside the EU.

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.

What is kOS, and do I need it?

kOS is KlusAI's AI workspace for documents, knowledge and agents. You don't need it for AI Blades or the AI Gateway.

Is Outpost available?

To design partners. Tell us about your setup.

Where do the GPUs run?

In EU data centres only, operated by EU-headquartered cloud providers.

Can a university pay by invoice?

Yes. We issue a pro-forma and an invoice from KlusAI Labs SRL, with reverse charge for EU VAT-registered institutions.

Do students need an account or a card?

They need an account to join, but never a card. The event's organiser pays for its GPUs.

What happens when a lab or event ends?

Its GPUs stop at the end time, and billing stops with them.
