| We are building **Soma**, a foundation model for continuous physiological signals from wrist wearables. During training, sports video, audio, metabolic-chamber and lab measurements label the wristband's raw streams: PPG, accelerometer and skin temperature. At inference, the model needs only the wristband. |
|
|
| Our models will be published here. |
|
|
| ## First release: Soma-ACC (coming soon) |
|
|
| A cross-device wrist accelerometer model. Every 30 seconds, it tells what a person is doing and whether they are asleep, from wrist motion alone. No camera, no microphone. |
|
|
| | | | |
| |---|---| |
| | **Input** | Raw 3-axis wrist accelerometer data from any device. The model does not need to know which device. | |
| | **Output** | Every 30 seconds: an activity label scored against text descriptions of activities, plus a sleep probability. | |
| | **Training data** | Public datasets only. Every dataset is credited in the model card. | |
| | **Evaluation** | On people held out from training, with the device treated as unknown. | |
|
|
| ## Principles |
|
|
| - **Public data, credited.** Every dataset we train on is named and credited in the model card. |
| - **Held-out people, unknown devices.** We report results on people the model never saw, with device identity hidden at test time. |
| - **Models produce the numbers; language models phrase them.** LLMs never generate physiological values. |
| - **Wellness and research, not medicine.** Our models are not medical devices and are not intended to diagnose, treat or prevent any disease. |

| Have reference measurements, such as sports video, metabolic-chamber data or lab tests? Let's pair them with continuous wrist signals: [contact@somaticai.io](mailto:contact@somaticai.io) |
