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

User reports running Qwen3.8 Flash-Next on a Minisforum Strix Halo 128GB box, sustaining 40 to 50 tokens per second on a one-shot meteor game smoke test. Setup uses Vulkan rather than ROCm, with MTP speculative decoding at depth 4 and context set to 128K minimum. The user notes the box cost £3500 and that the DGX Spark is about 20% more expensive with similar 256GB/s memory bandwidth.
