Summary
User reports Qwen3.8 Flash-Next at ~60 t/s on a rented RTX Pro 6000 Blackwell 96GB.
Setup uses the Q4_K_M GGUF, which the user notes is not efficient for this card but was chosen because abliterated models that fit the memory are limited.
The rental costs about $30/day on Vast, and the user is asking which hardware configuration would offer the best price and versatility for future model generations.
