Apache-2.0 — inherited unchanged from the base model (Qwen3.8-27B lineage).
Weight-only quantization; no rights are widened.
Quantization (self-hosted, reproducible)
- Tool:
gptqmodel==7.3.2 on CUDA (RTX 5090), lazy checkpoint loading;
calibration wikitext-2 (or bundled fallback text).
- Contract:
bits=4, group_size=128, desc_act=false, sym=true, lm_head=false, dynamic={"-:.*mtp.*":{}}
(MTP tensors stay BF16).
- Source fp16 (~50 GB) → quantized ~18.2 GB / 5 shards; config arch
Qwen3_5ForConditionalGeneration, image_token_id 248056.
