Qwen3.8-Flash-Next needs only 6B active parameters per token, so the internet decided it runs on 12GB of VRAM. It does — but only if you also have 75GB of total memory and an SSD willing to stream a 51B n-gram table. Here is the real memory table, the benchmark delta against the 27B you can already run on one 24GB card, and the two conflicting offload recipes reconciled.
