A checkpoint-specific calibrated quantization of Qwen/Qwen3.8-Flash-Next for the Radiance inference engine. This repository contains a single self-contained.rad inference container. It is not a Transformers, safetensors, llama.cpp, or vLLM checkpoint. Use a Radiance build with the Qwen3.8-Flash-Next model support and w4nl/w5nl expert kernels. - All 48 calibrated trunk layers use GPTQ with three coordinate-descent sweeps. - Routed expert down projections use non-linear w5nl (5-bit) codebooks, group 64, E4M3 scales, and FWHT128. - Routed expert gate/up projections use w4nl (4-bit) with the same transform and group structure. - Ten selected high-energy routed experts remain BF16. - Attention…
