What was changed
This is a modified (quantized) version of the original Qwen3.5-4B weights:
- The language model's Linear layers are quantized with bitsandbytes NF4, double quantization,
bf16 compute dtype.
- The vision tower (
model.visual) and lm_head are left unchanged in bf16.
The copy was made by FacadeLab's deterministic builder (fixed recipe; transformers 5.2.0,
bitsandbytes 0.49.2, torch 2.9.1, built on CUDA). facadelab_build.json records the source
repository and revision, the recipe, the software stack, and the size and sha256 of every other
file in this repository.
