Where the Bits Go: Non-Uniform Quantization of Qwen3.5-9B
Not all parts of a model deserve the same precision. We present a quantization stack that spends a fixed bit-width budget across a model, allocating precision where it matters most. Applying it to Qwen3.5-9B, we produce a family of models at different compression levels, all runnable on standard llama.cpp. Our findings show that smart allocation and representation choice significantly improve the reasoning ability of aggressively quantized models.
