Summary
User reports Qwen3.8 Flash Next at ~100 t/s generation on 2x Radeon AI PRO R9700 with 128GB system RAM.
Setup uses the R9V engine with an IQ4_XS GGUF and n-gram SSD streaming, which the user says fixed crashes after ~12 hours of torture testing.
Q4_K_XL is now supported at 50 t/s generation but the user notes it still needs fine tuning.
