LLM-Based Personalized Health Solution

WHOOP monitors physical data such as sleep and stress 24 hours a day through its wearable device. It had previously analyzed data using machine learning, but has now decided to introduce generative AI to provide users with an entirely new kind of coaching.

The WHOOP engineering team conducted an experiment integrating OpenAI's GPT-4 into the app. By fine-tuning GPT-4 using anonymized member data and WHOOP's proprietary algorithms, they implemented highly personalized, conversational responses based on individual data.

WHOOP Coach, launched this past September, provides instant answers when users ask questions about their own physical data. For example, it offers customized guidance in response to questions like "What's my all-time lowest resting heart rate?" or "What's my weekly workout plan to reach my goal?"

Currently, 40% of the questions received by WHOOP Coach are requests for recommendations, and the most popular question is "How can I improve my sleep quality?" Four out of the top 5 questions users ask are related to self-improvement, showing that Coach is helping users reach their goals faster.
