Field notes · Clinical data for AI research

Data from real clinical care, for frontier models.

Mozu Health licenses datasets and builds custom evaluations for AI labs that train and evaluate models on healthcare tasks. The data follows a visit from the conversation through the clinic’s work to the records and outcomes that follow.

In brief

What Mozu offers
Ready-to-license clinical datasets, plus datasets, evaluations and benchmarks built to your specification.
Who creates and grades it
Medical doctors with experience in the dataset’s specialty. The company is led by an Emergency Medicine physician.
How to request a sample

Field note 01 · Illustrative encounter

One visit, three layers of data.

A clinic visit is more than a conversation. Mozu’s datasets capture care at three levels. The visit below is fictional and written for illustration. It contains no patient data.

Telehealth primary care · Adult patient, 40s

Fictional example
  1. 09:02Visit

    “Three days of cough, worse at night. A low-grade fever since Tuesday.” The physician asks about breathing, sleep and contacts.

    Level 1The conversation between doctor and patient

  2. 09:18Clinic

    A chest X-ray is ordered and a follow-up video visit is booked for Friday. The note is routed for co-signature.

    Level 2The administrative work that runs the clinic

  3. Day 4Record

    The SOAP note is closed. At follow-up the fever has resolved and the cough is improving, and no further imaging is needed.

    Level 3The patient records and outcomes that follow

Linking a decision in the visit to the work and the outcome after it gives a model more to learn from than the transcript alone.

Datasets and use cases

Built for training and evaluation.

Each specialty works differently. To succeed at long-horizon tasks, models need to train on how care unfolds within each one.

Mozu datasets

Ready-to-license datasets drawn from real clinical care, with patient interactions, patient records, clinician decisions and outcomes.

Custom data development

Datasets, evaluations and benchmarks built to your specification, collected from clinical practice or created by experts.

  • Real-world data

    Large de-identified patient record datasets that map SOAP notes to real-world care.

    Use · Pretraining and evaluation

  • Reinforcement learning

    Clinical and administrative tasks with feedback grounded in the decisions and outcomes that follow an encounter.

    Use · Long-horizon clinical tasks

  • Benchmarks and evaluations

    Tests designed around meaningful clinical work, typically by specialty or by type of clinic or hospital.

    Use · Measuring a model by specialty or setting

  • Expert data

    Created and graded exclusively by medical doctors with experience in the specialty of the dataset being built.

    Use · Tasks that need clinical judgment

Specialties today

Physician-led

Doctors make the data, and grade it.

Mozu’s founder and CEO, Mai Shimada, MD, is an Emergency Medicine physician trained in the United States and Japan. Physicians, engineers and repeat company builders make up the team in San Francisco and Tokyo.

Expert data is created and graded exclusively by medical doctors with experience in the specialty of the dataset being built.

Mozu is the name of a bird known for its ability to communicate. We believe the words of patients from around the world are critical to improving AI models.
