New study raises concerns about free AI chatbots

15 Apr 2026

Much of the medical advice provided by free generative AI chatbots is inaccurate and have potentially dangerous limitations, reported Business Day (15 April 2026). According to a study published in the British Medical Journal (BMJ) almost half of the responses were found to be below acceptable standards; 20% were highly problematic and 30% were somewhat problematic. The research highlights concerns regarding the reliability of these chatbots as they cannot make ethical or value-based judgments and often produce authoritative-sounding but flawed responses.
The research (February 2026) focused on five free versions Gemini ChatGPT, DeepSeek, Meta AI and Grok.
