Researchers developed M-QUEST, a new benchmark for evaluating AI models' ability to understand and detect toxicity in internet memes. The framework identifies 10 key dimensions for meme interpretation and tests 8 open-source language models, finding that instruction-tuned models perform better but still struggle with pragmatic inference.
