## Model Format

- **Quantization** — established across all LLM endpoints; each service (radiance, halogen-flash-server, llama.cpp) applies its own quantization scheme as part of the runtime.
- **Qwen3.8-Flash-Next `.rad`** — radiance container uses `.rad` format natively; the format encodes routed experts as 4-bit codes into a 16-level non-uniform codebook (128-pt Walsh–Hadamard rotation, GPTQ on calibration + 3 coordinate-descent sweeps, E4M3 scales per 64 weights), with 10 whole bf16-protected experts/layer, int8 W8A8 trunk/lm_head, fp8 HC mixtures, and fp8 fixed-scale PLE n-gram.
