Running It Around the Clock
| Precision | Cheapest setup | Per hour | Per month (730 hours) |
|---|---|---|---|
| 16-bit | 3x MI325X (Vultr) | $6.00 | $4,380 |
| 8-bit | 2x MI300X (Vultr) | $3.70 | $2,701 |
| 4-bit | 1x MI300X (Vultr) | $1.85 | $1,350 |
One copy of the model on rented cards, busy or idle. Serving more users at once takes more copies or more memory for their contexts.
Questions
How much VRAM does DeepSeek-V4-Flash-0731 need?
About 730 GB at 16-bit; about 365 GB at 8-bit; about 182 GB at 4-bit: the weights plus 20% for the runtime and a short context. A long context needs more.
What is the cheapest GPU setup to run DeepSeek-V4-Flash-0731?
At 16-bit, 3x MI325X from $6.00 an hour, at the lowest on-demand price the SAVRN Index lists.
Can DeepSeek-V4-Flash-0731 run on a single H100?
No. An H100 has 80 GB, and DeepSeek-V4-Flash-0731 needs 182 GB even at 4-bit, so it takes more than one card.
Memory is the weights at that precision plus 20% for the runtime and a short context. Prices are the lowest on-demand hourly rates in the SAVRN Index, read Sep 18, 2026. Setups beyond eight cards, one server, are not listed.
