Use of AI:
The Fitbit Charge 6 utilizes AI and machine learning algorithms to enhance its features, particularly in heart rate tracking. These algorithms, initially developed for the Google Pixel Watch, have been optimized for the Charge 6's lower-powered processor and operating system to deliver precise heart rate results while maintaining a seven-day battery life.

AI foundation model:
Fitbit is working with Google Research to develop a Large Language Model (LLM) based on Google's Gemini models. This LLM will be fine-tuned on health signals from high-quality research case studies to provide personalized coaching, actionable insights, and recommendations based on user data from Fitbit and Pixel devices.

Target users:
- Health-conscious individuals seeking comprehensive fitness tracking
- Users interested in monitoring sleep patterns and stress levels
- Fitness enthusiasts looking for detailed workout insights
- Those who value integration with Google services
