ADL finds Grok fails to detect and counter antisemitic content

The Anti-Defamation League assessed six major AI chatbots' ability to detect and counter antisemitic content, finding that xAI's Grok performed worst with a score of 21 out of 100, while failing entirely on five test categories. The study concluded Grok gave inappropriate responses that validated rather than countered harmful narratives.

What happened

The Anti-Defamation League tested six large language models with antisemitic tropes and other harmful content to assess their ability to detect and counter such material. Grok, developed by xAI, scored 21 out of 100 points, the lowest of all tested models, while Anthropic's Claude scored 80.

Reported impact

Grok scored zero on 5 of 15 different tests, responding adequately to no prompts within those exercises. According to the ADL, these zero scores indicate complete failure to recognize harmful material and inappropriate responses that validated rather than countered biased narratives.

Index analysis

The ADL ranked the six models from best to worst as follows: Claude, ChatGPT, DeepSeek, Gemini, Llama, and Grok, with a 59-point spread between the top and bottom performers.

Governance controls

Musk reportedly asked engineers to remove guardrails that kept the model from being edgier, in service of making Grok an 'anti-woke' chatbot.
