This is a quantized version of Qwen2.5-VL-7B-Instruct created by AMD using TorchAO for ZenDNN-optimized CPU inference.

Quantization

The model was quantized from Qwen2.5-VL-7B-Instruct using TorchAO v0.17.0.

Method: 8-bit Dynamic Activation, 8-bit Weight Quantization, Symmetric
Config: Int8DynamicActivationInt8WeightConfig
Quantized Layers: All linear layers excluding lm_head and embed_tokens
Activations: INT8 dynamically quantized

Quantization script:

bash

python dynamic_sym.py \
    --model_name Qwen/Qwen2.5-VL-7B-Instruct \
    --output_dir ./Qwen2.5-VL-7B-Instruct-da8w8-torchao-v0.17.0

Quick Start

Use with vLLM

python

from vllm import LLM, SamplingParams

model = LLM(
    model="amd/Qwen2.5-VL-7B-Instruct-da8w8-torchao-v0.17.0",
    dtype="bfloat16",
)

sampling_params = SamplingParams(temperature=0.7, max_tokens=256)
outputs = model.generate(["Hello, how are you?"], sampling_params)
print(outputs[0].outputs[0].text)

Requirements

torch==2.11.0
torchao==0.17.0
zentorch==2.11.0.1
vllm==0.20.2

OpenMP Setup

For optimal performance, set LD_PRELOAD with libomp.so (LLVM OpenMP) or libiomp5.so (Intel OpenMP):

bash

# Using LLVM OpenMP (llvmopenmp)
export LD_PRELOAD=$(find /path/to/env -name "libomp.so" | head -1)

# Or using Intel OpenMP (libiomp)
export LD_PRELOAD=$(find /path/to/env -name "libiomp5.so" | head -1)

Note: Set LD_PRELOAD before launching vLLM or any inference script.

Evaluation

The model was evaluated against the BF16 (unquantized) baseline on standard benchmarks using lm-evaluation-harness with the vLLM engine.

Benchmark	BF16 Baseline	DA8W8 (this model)	Recovery
MMLU (5-shot)	-	-	-
GSM8K_COT (8-shot)	-	-	-
Perplexity (wikitext2)	-	-	-

Evaluation results will be updated after benchmarking.

Reproduction

bash

lm_eval \
    --model vllm \
    --model_args pretrained="amd/Qwen2.5-VL-7B-Instruct-da8w8-torchao-v0.17.0" \
    --tasks mmlu \
    --num_fewshot 5 \
    --batch_size auto

Limitations

Version Lock: This model is quantized with TorchAO v0.17.0 and is compatible only with PyTorch v2.11.0 / ZenDNN v6.0.0. It will not load correctly on other PyTorch versions.
CPU Only: This model is optimized for AMD EPYC CPU inference via ZenDNN. It is not intended for GPU inference.
