ŌURA, maker of the Oura Ring, has announced its first proprietary large language model (LLM) built specifically for women’s health. Rolling out in testing through Oura Labs, the model enhances the Oura Advisor experience with clinically grounded, personalized guidance across the full reproductive health spectrum: from early menstrual cycles to menopause.
Unlike general-purpose AI systems, ŌURA’s custom model is trained on established medical standards, peer-reviewed research, and curated knowledge sources vetted by the company’s in-house board-certified clinicians and women’s health experts. It also integrates real-time biometric signals and long-term trends across sleep, activity, stress, cycle tracking, and pregnancy data to deliver contextual, evidence-based insights.
A Shift Toward Purpose-Built Health AI
“This custom model is a fundamental shift in how we responsibly deploy AI in health,” said Ricky Bloomfield, MD, chief medical officer at ŌURA. “Women’s health is too complex and too often overlooked to rely on one-size-fits-all systems.”
The launch represents a broader strategic pivot for ŌURA: moving beyond general AI tools and toward deeply specialized, empathetic models tailored to specific health use cases. The system is intentionally tuned to provide non-dismissive, reassuring responses, helping women better understand patterns in their own data and prepare for conversations with healthcare providers.
Chris Curry, MD, ŌURA’s clinical director of women’s health and a board-certified OB/GYN, emphasized that many women’s health questions are personal and high-stakes. For example, if a member asks why their cycle has become irregular, Oura Advisor can explain typical causes, analyze relevant personal data trends, and suggest what to discuss with a clinician, translating complex science into accessible guidance.
Establishing a New Standard
The timing reflects broader behavioral shifts. A 2025 survey found nearly 80% of U.S. adults search online for health symptoms, and almost two-thirds encounter AI-generated responses. As women increasingly turn to AI for insight into perimenopause, hormonal shifts, and fertility questions, the demand for clinically grounded and context-aware models is rising.
ŌURA’s women’s health LLM is built on the company’s own infrastructure and leverages knowledge-graph technology from webAI. Conversations remain private and are not shared or sold, aligning with the company’s stated privacy-first AI strategy.
Member-Led Testing
Participation in Oura Labs is optional, allowing members to test new features and provide feedback before broader rollout. Those who opt in contribute to refining the model’s accuracy and usefulness across areas such as fertility, pregnancy, and hormonal health, turning individual data insights into collective learning.
