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 sph_baseline1_openmobile_sft need?
About 21 GB at 16-bit; about 10.5 GB at 8-bit; about 5.3 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 sph_baseline1_openmobile_sft?
At 16-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand price the SAVRN Index lists.
Can sph_baseline1_openmobile_sft run on a single H100?
Yes at 16-bit, 8-bit, 4-bit: an H100 has 80 GB and sph_baseline1_openmobile_sft needs 21 GB at 16-bit.
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 Oct 22, 2026. Setups beyond eight cards, one server, are not listed.
