GPU specialist against peer marketplace, 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.
packet.ai is cheaper on 2 of the 3 cards both of them rent, by a median of 12%. The two match on 1 of the rest.
These are not the same product. A GPU specialist and a peer marketplace 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.
| packet.ai | Spheron | |
|---|---|---|
| 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. | Hourly, per-second metered | Per minute |
| Minimum commitment | None on hourly | None on dedicated or spot |
| Payment model | Prepaid wallet · subscription · invoice | Prepaid credits, USD; enterprise invoicing on request |
| Free credits | $10 + 10k tokens | not stated |
| Egress | Free | Network bandwidth included in the hourly rate |
| Uptime SLA | 99% monthly (Dedicated) | 99.9% |
| Regions | California, Virginia, Texas, Oregon, Frankfurt, Amsterdam, Paris, London, Dublin | North America, Europe, Asia Pacific |
Neither site tells you 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.
Nothing the other does not also rent.
packet.ai is cheaper on 2 of the 3 cards both of them rent, by a median of 12%. The two match on 1 of the rest.
NVIDIA A100 80GB, NVIDIA L40S 48GB, NVIDIA RTX 4090 24GB — 3 in total, on published per-GPU on-demand rates.
Of the cards both rent, packet.ai starts at $0.39 per GPU-hour and Spheron at $0.48.
No. packet.ai is a GPU specialist — an operator whose whole business is renting these cards. Spheron is a peer marketplace — a stranger whose machine the platform vets to some degree. Reliability, bandwidth and how long the machine stays online vary by host, not just by price. The rates are comparable; what stands behind them is not.
