Model Card

SNIFFER is a multimodal large language model specifically engineered for Out-Of-Context misinformation detection and explanation. It employs two-stage instruction tuning on InstructBLIP, including news-domain alignment and task-specific tuning.

The whole model is composed of three parts: 1) internal checking that analyzes the consistency of the image and text content; 2) external checking that analyzes the relevance between the context of the retrieved image and the provided text, and 3) composed reasoning that combines the two-pronged analysis to arrive at a final judgment and explanation.

Here the checkpoint is used for the internal checking part.
