Google Research and Fitbit are working on a Personal Health Large Language Model, meaning an AI-based personal trainer to help you stay fit and healthy.

In a blog post Tuesday, Google explained that the new model will power personalized health and wellness features in the Fitbit mobile app, providing insights and recommendations based on the data it gathers from Fitbit and Pixel devices.

If you recall, Google acquired fitness wearables maker Fitbit back in 2021, with the company now selling both Fitbit-branded devices and Google's Pixel Watch 2.

Google offers several examples of what the new AI model can do, such as analyze variations in your sleep patterns and sleep quality, and then suggest recommendations on what your next workout should be like in terms of intensity.

The model is built on Google's new Gemini models, and "fine-tuned on a de-identified, diverse set of health signals from high-quality research case studies," Google said. It's all done in partnership with coaches and wellness experts, of course.

Google says that the model already has good results in some areas. "We’re testing performance using sleep medicine certification exam-like practice tests, and are already seeing that our model currently performs well," the company wrote, adding that it will share more research "soon."

There's no word on when we'll actually see the new AI features in action in the Fitbit app.
