Simon Fraser University researchers found that major generative AI chatbots sometimes direct health inquiries to unregulated information from private medical providers.
The Story
Researchers at Simon Fraser University in Burnaby tested six generative AI chatbots—ChatGPT, Claude, DeepSeek, Gemini, Grok and Llama—by asking questions about conditions tied to stem cell treatment, including Alzheimer’s disease, autism and cerebral palsy.
The researchers said the chatbots can point users to information involving businesses, raising concerns because some of that material is unregulated when it comes from private medical providers.
The study’s findings were presented as a warning to people considering using chatbots for health advice, particularly when the information could be linked to stem cell-related claims and treatments.
