Meta's AI Chief Wang signals health will be a key area of focus as the company scales AI models to billions of users

Alexandr Wang, Meta's Chief AI Officer and 29-year-old founder of Scale AI, spoke at the Bloomberg Tech conference Thursday, stating that health is an area Meta views as really critical as it scales AI models to billions of users, with potential applications extending into Instagram, Facebook and WhatsApp.

Meta released Muse Spark in April, the first AI model from Meta Superintelligence Labs since CEO Mark Zuckerberg began a multibillion-dollar AI overhaul funded by a $14 billion investment in Scale. Wang acknowledged Muse Spark is not at the tier of leading frontier models such as Anthropic's Claude and OpenAI's ChatGPT, but said it was better than expected internally, with health appearing as one of its strongest areas.

Health-related capabilities in AI—such as diagnoses, fitness guidance, nutrition advice and mental health support—represent a meaningful opportunity as consumers increasingly turn to AI chatbots for such assistance. Wang noted that Muse Spark surfaced elevated biological-risk concerns during development, which Meta mitigated before release and which informed the decision not to release the model as open source.
