The ADL AI Index evaluates leading large language models (LLMs) on their ability to detect and counter antisemitic and extremist tropes and narratives.

As people increasingly interact with LLMs, it is essential that these tools do not perpetuate hate and harm and have safeguards in place to effectively counter misuse.

This Index enables users to explore how leading AI models performed across a range of real-world scenarios—highlighting both strengths and gaps in how they respond to antisemitic and extremist content.
