We have patented the clinical layer that makes LLMs safe for healthcare. We are proud to share that the European Patent Office (EPO) has granted Ada Health a patent for its hybrid AI architecture — an ensembling approach that combines the strengths of large language models with clinical precision, explainability, and regulatory standing. Ada’s hybrid engine includes an LLM on the front end, which allows users to describe symptoms, medical history, medications, and preferences in their own words, capturing the clinical nuance and contextual detail crucial to pre-diagnosing complex or rare conditions. The system dynamically prompts users with medically relevant follow-up questions constrained to Ada’s validated knowledge base, preventing ungrounded outputs that arise from unconstrained LLM use in clinical settings. This is a structural safeguard built into the architecture. Finally, the patented hybrid model assesses symptoms independently, with the LLM functioning as a second opinion alongside Ada’s expert-curated medical knowledge base. The two models are ensembled:  Ada’s reasoning engine acts as a guardrail, while improving relative accuracy by more than 7% and preserving the rigour that medical-grade deployments demand. The result is a fully white-box, auditable clinical reasoning system. The data insight and explainability of Ada’s outputs, which have been running at population scale since 2016, continues to be a crucial feature for its industry-leading pharma, health systems, and payer partners around the world. “LLM providers are discovering that scale and medical safety are not the same.  Ada has spent over a decade building the clinical infrastructure that makes AI safe to deploy in healthcare — the validated knowledge base, the regulatory certification, the safeguarding protocols. This patent protects the architecture that brings all of that together with the power of modern language models. It is the clinical layer the industry has been waiting for.” Daniel Nathrath Founder and CEO, Ada Health #Healthcare #LLM #AI
