AnomalyThink-Qwen2.5-VL-7B-SFT

Supervised-fine-tuning-only baseline (DS-MVTec 80.16 / VisA 64.78).

A Qwen2.5-VL-7B model fine-tuned for explainable industrial anomaly detection (IAD). Given a product image it produces a structured reasoning trace (<think>), a defect <location> and <type> (for anomalies), and a binary <answer>. Research artefact from the MSc thesis Reasoning-Enhanced Vision-Language Models for Explainable Industrial Anomaly Detection (TU Delft, 2026).

Results (MMAD subsets, balanced accuracy)

Benchmark	Balanced accuracy
DS-MVTec (1,670)	80.16%
VisA (2,141)	64.78%

Evaluated under a single common harness on the MMAD DS-MVTec and VisA subsets. This is the SFT-only headline before any RL stage.

Training

Supervised fine-tuning on the AnomalyThink-6K corpus (6,000 Gemini-2.5-Flash traces, vision encoder frozen, epoch 3 of 4).

The "AnomalyThink" reasoning traces were distilled from Gemini 2.5-Flash on Real-IAD images. Training data: aacudad/AnomalyThink.

Usage

import torch
from transformers import AutoProcessor, Qwen2_5_VLForConditionalGeneration
model = Qwen2_5_VLForConditionalGeneration.from_pretrained("aacudad/AnomalyThink-Qwen2.5-VL-7B-SFT", torch_dtype=torch.bfloat16, device_map="auto")
processor = AutoProcessor.from_pretrained("aacudad/AnomalyThink-Qwen2.5-VL-7B-SFT")
# Build the structured single-image IAD prompt + image, then generate.

Intended use and limitations

Research on explainable IAD. Known limitations: the model can confidently hallucinate a defect on a normal part (false positive), and GRPO-lineage variants can over-predict the "Missing Parts" type. As the public DS-MVTec/VisA images may appear in VLM pretraining, absolute numbers should be read with that caveat.
