What GPU do I need to run Qwen3.8-Flash-Next?

Qwen3.8-Flash-Next has 176B parameters (6B active per token, mixture-of-experts). At Q4_K_M with 8K context it needs about 107.8 GB of memory. It needs a large unified-memory machine such as the M3 Ultra 256GB, or a multi-GPU setup. Because only 6B parameters are active, it still runs usably with offload to system RAM on cards like the RTX PRO 6000 Blackwell.
