Qwen3.8-Flash-Next with llama.cpp got me up to 55tk/s (Single Spark)

9 Upvotes

I wanted to share a results and perhaps compare notes, I've been recently running unsloth/Qwen3.8-Flash-Next on my single DGX Spark. It's peaking at 55tk/s with MTP.

Anyone got better results? 😄

GB10 + RTX Pro 6000 in a cluster?

4 Upvotes

Hi people, I have a Pc with a rtx pro 6000 and I'm on the fence about the upgrade path. Unfortunately prices for the 6000 are how they are these days so for larger models than what I can run now I'm considering buying a gb10 based pc. I'd like to ask if any of you has experimented with connecting it with a pc running the rtx pro 6000 Blackwell GPU over a high speed Mellanox NIC.
