GPU specialist against general-purpose cloud, priced against each other on the 3 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 3 of the 3 cards both of them rent, by a median of 25%.
These are not the same product. A GPU specialist and a general-purpose cloud differ in who your counterparty is, which is why the rates below can be far apart without either being wrong. The prices are comparable; what stands behind them is not.
The 3 cards both of them rent, cheapest published per-GPU on-demand rate each. Dearest first.

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.
| Massed Compute | Scaleway | |
|---|---|---|
| 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 hour, pay as you go |
| Minimum commitment | None; prepaid balance with $5 minimum threshold | None |
| Payment model | Prepaid balance with automatic recharge | Pay as you go — you pay for what you use |
| Free credits | Referral credit 3% of referred spend; coupon codes | not stated |
| Egress | Free | not stated |
| Uptime SLA | 99.999% claimed on product page; no SLA document found | 99.5% monthly availability for GPU Instances |
| Regions | US regions (e.g. us-central-3); locations not named | Paris (France), Amsterdam (Netherlands), Warsaw (Poland) |
Neither site tells you how fast support answers or whether a commitment auto-renews. We looked on both and record the absence rather than filling it in — if you need any of it, ask before you commit.

No. Massed Compute is a GPU specialist — an operator whose whole business is renting these cards. Scaleway is a general-purpose cloud — a hosting company where GPUs sit beside the VPS products, on the same account and billing. The rates are comparable; what stands behind them is not.
