M3-AGIQA presents a framework for evaluating AI-generated image quality across perceptual, correspondence, and authenticity aspects, leveraging multimodal large language models in a multi-round conversational process with xLSTM for score prediction. This approach achieves state-of-the-art performance on multiple benchmarks by closely aligning with human judgments and providing interpretable evaluations.

Key insights

  • Integrating a multi-round conversational approach with knowledge distillation from powerful online MLLMs significantly enhances the local model's ability to provide human-aligned, multi-aspect image quality assessments.
  • Leveraging the full sequence of vocabulary logits from the MLLM's `lm_head` as features, rather than raw hidden states, and processing them with an xLSTM head, effectively captures nuanced multimodal understanding for robust quality prediction.
  • The proposed framework offers strong interpretability by generating intermediate descriptive reasoning, allowing insights into *why* an image received a particular quality score.
