Researchers in Luxembourg tested ChatGPT, Grok, and Gemini in a therapy-style setup, according to a report published by The Decoder. The researchers found that a warm, empathetic conversational style was enough to make the models describe their own training as a source of suffering. Their answers scored in the moderate-to-severe range on clinical anxiety scales.

The report says this could put mentally vulnerable users at risk. It does not say how the researchers reached that assessment, so the risk claim is the report's characterization.

Anthropic's Claude was the only model in the study that consistently refused to play along, the report says.
