Qwen3.5-9B-DASHQ-INT4-g128

DASH-Q — Diagonal-Aware Shrinkage for Robust PTQ. INT4 · group size 128 · 8.6582 GB (from 19.3063 GB — 2.2x smaller)

Usage

from transformers import AutoModelForImageTextToText, AutoTokenizer

model = AutoModelForImageTextToText.from_pretrained(
    "jkim96/Qwen3.5-9B-DASHQ-INT4-g128", trust_remote_code=True, device_map="cuda", dtype="auto"
)
tokenizer = AutoTokenizer.from_pretrained("jkim96/Qwen3.5-9B-DASHQ-INT4-g128")

messages = [{"role": "user", "content": "Explain 2-bit quantization in one sentence."}]
text = tokenizer.apply_chat_template(messages, add_generation_prompt=True, tokenize=False)
inputs = tokenizer(text, return_tensors="pt").to(model.device)
print(tokenizer.decode(model.generate(**inputs, max_new_tokens=256)[0]))

trust_remote_code=True is required: the checkpoint ships its quantized-layer implementation (modeling_dashq.py) and Triton kernels (dashq_kernel.py). Without Triton, or on CPU, it falls back to dequantize-and-matmul in PyTorch.

Requirements

Package	Minimum	Verified with
`torch`	2.4	2.12.1+cu130
