These are not the same product. A peer marketplace and a GPU specialist 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.
| Spheron | Together AI | |
|---|---|---|
| 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 | Hourly for clusters; per token, megapixel or second for serverless |
| Minimum commitment | None on dedicated or spot | $5 minimum credit; no term on on-demand |
| Payment model | Prepaid credits, USD; enterprise invoicing on request | Prepaid credits, then invoices with itemised usage |
| Free credits | not stated | None — no free trials |
| Egress | Network bandwidth included in the hourly rate | FREE on managed storage |
| Uptime SLA | 99.9% | not stated |
| Regions | North America, Europe, Asia Pacific | not stated |
Neither site tells you whether a commitment auto-renews, how long you have to dispute a bill or how much warning you get before maintenance. We looked on both and record the absence rather than filling it in — if you need any of it, ask before you commit.
