Darwin-397B-JGOS GPU Requirements
Darwin-397B-JGOS needs about 968 GB of GPU memory at 16-bit, 484 GB at 8-bit and 242 GB at 4-bit: its 403.4B parameters plus a 20% working margin. The cheapest setup at 16-bit is 4x MI325X from $8.00 an hour, about $5,840 a month around the clock. None of the 9 accelerators the SAVRN Index prices holds it on one card at 16-bit.

Running It Around the Clock
| Precision | Cheapest setup | Per hour | Per month (730 hours) |
|---|---|---|---|
| 16-bit | 4x MI325X (Vultr) | $8.00 | $5,840 |
| 8-bit | 2x MI325X (Vultr) | $4.00 | $2,920 |
| 4-bit | 1x MI325X (Vultr) | $2.00 | $1,460 |
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 Darwin-397B-JGOS need?
About 968 GB at 16-bit; about 484 GB at 8-bit; about 242 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 Darwin-397B-JGOS?
At 16-bit, 4x MI325X from $8.00 an hour, at the lowest on-demand price the SAVRN Index lists.
Can Darwin-397B-JGOS run on a single H100?
No. An H100 has 80 GB, and Darwin-397B-JGOS needs 242 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 23, 2026. Setups beyond eight cards, one server, are not listed.
