Qwen3.8 125B (6B active) Flash-Next

User reports Qwen3.8-Flash-Next at 1700.52 t/s prompt processing and 25.95 t/s generation on an AMD Strix Halo 128GB. Setup is Gufo with an Unsloth UD-Q4_K_XL GGUF, single-user autoregressive with no speculative decoding, greedy sampling, thinking off, at cached depth zero (prompt_n 2040, predicted_n 128). This is an engine-maintainer measurement, not an independent reproduction, and the measured binary was built from a dirty source tree. Allocated context capacity is 133760 tokens, not prompt length. MTP, aggregate concurrency and cached-depth rows are separate workloads.
