Two GPU specialist providers, priced against each other on the 4 GPUs both of them rent. Published per-GPU on-demand rates as each provider last stated them, with what their own pages say about billing, commitment and egress beside the numbers.
Massed Compute is cheaper on 4 of the 4 cards both of them rent, by a median of 41%.
The 4 cards both of them rent, cheapest published per-GPU on-demand rate each. Dearest first.

| NVIDIA RTX A6000 48GB | $1.09/hr | $0.55/hr | 50% cheaper on Massed Compute |
Per GPU per hour, on-demand list prices as each provider last published them. Rates exclude tax and vary by region; a cheaper rate is not the same machine, the same network or the same support.
| Lambda | Massed Compute | |
|---|---|---|
| Billing granularityOn short jobs this outweighs the rate: an hour minimum on a 90-second run costs more than a 30% dearer per-second rate. | Per minute | Per minute |
| Minimum commitment | None on demand; 2 weeks on clusters | None; prepaid balance with $5 minimum threshold |
| Payment model | Postpaid, weekly invoices; clusters invoiced on reservation | Prepaid balance with automatic recharge |
| Free credits | not stated | Referral credit 3% of referred spend; coupon codes |
| Egress | Free | Free |
| Uptime SLA | not stated | 99.999% claimed on product page; no SLA document found |
| Regions | 14 regions: US (9), Japan (2), India, Germany, Israel | US regions (e.g. us-central-3); locations not named |
Neither site tells you whether you get credits when it breaks, whether a commitment auto-renews, how long you have to dispute a bill or whether private networking exists. We looked on both and record the absence rather than filling it in — if you need any of it, ask before you commit.
