This being /u/jacquesm would imply it is kinder to assume him having that setup than claiming to have that setup.

Even 2 DGX sparks are limited to Q2 at best. As for GPUs, it of course depends, but anything under 50k just can't run it, not even Q2.

And at Q2, I think you're better of with Qwen3-coder-next on one DGX spark (or much better: on any apple silicon max, we are currently in the ridiculous situation that a second hand m1 max 64G will beat a DGX spark that's at least triple the price)
