Grace Blackwell GB10 · Now seeking founding members

Private GB10 inference on real hardware. Pay by the minute.

RentaSpark is a marketplace where NVIDIA DGX Spark owners list their idle machines — and anyone can rent a full Grace Blackwell GB10, not a slice of a shared cluster. We're validating both sides now. Sign up as an owner or as a renter and help us build it.

How it will work

1

Reserve a GB10

Pick a verified slot, choose how long, load credits.

2

Start a session

Get your base URL and session token.

3

Run inference

Call the OpenAI-compatible API; we meter by the minute and forward to your machine.

4

Stop when done

The session closes, metering stops, your owner earns.

Supply side · Equipment holders

Own a DGX Spark? Put it to work.

Your Grace Blackwell sits idle most of the day. List it on RentaSpark and earn from every minute someone runs inference on it. You set your rate and your hours — we handle billing, payouts, and the customer.

  • 85% — your share of every session
  • You — set the rate and the hours
  • List one machine or several, in minutes

We're collecting expressions of interest from equipment holders now. Tell us about your hardware and we'll be in touch as the marketplace opens.

Demand side · Renters

Want private GB10 compute by the minute?

Run 70B+ models on a whole machine without buying the hardware. Drop in the OpenAI-compatible API, load a session token, and go. No queue, no cloud markup, no monthly commit.

  • OpenAI-compatible — works with Cursor, LangChain, any SDK
  • Per-minute billing, no egress fees
  • Your own machine, not a shared slice

We're collecting expressions of interest from renters now. Tell us what you'd run and you'll be first in line when slots go live.

Built on trust

A marketplace for compute only works if both sides trust the plumbing. Every slot gets its own access token, encrypted at rest and shown to you exactly once. Endpoints must be public HTTPS — plain HTTP, localhost, and private ranges are rejected. Continuous health checks publish each slot's uptime as a badge renters can see.

FAQ

What is a GB10?

The NVIDIA Grace Blackwell GB10 — the processor in a DGX Spark. 128 GB unified memory, 1 PFLOP FP8, NVLink-C2C. Runs 70B+ parameter models.

Is this the same as renting a cloud GPU?

No. This is a whole, real GB10 machine you or another owner runs, not a slice of a shared cluster and not a rate-limited API wrapper. The platform brokers, meters, and bills — the hardware is real and private.

How does billing work?

Pre-load credits, run inference, stop. Billed per whole minute. No monthly commit, no egress fees.

How do owners get paid?

Owners keep 85% of every session. Earnings accrue live and pay out once you clear the minimum.

Can I be both an owner and a renter?

Yes. List your idle Spark and rent others when you need capacity elsewhere.
