Vector quantization of Qwen3.5-397B-A17B, Qwen3.6-35B-A3B and the dense Qwen3.8-27B, measured against data-free round-to-nearest affine quantization with every other tensor held byte-identical. No calibration data. The VQ builds measured in the paper are published: https://huggingface.co/TheDrainFlorist
