TL;DR: Today, I’m releasing ClinicalEncoder26AM, an interpretable non-generative reasoning model that understands multilingual clinical texts at millisecond speed, with token-level precision. Built on the new Diagnosable ColBERT architecture, it maps every word to a semantic clinical graph, enabling real-time reasoning and retrieval. It also enables debugging, with every token becoming an opportunity to uncover misunderstandings and potential mistakes, providing a level of interpertability never seen yet in ColBERT models.

Stop generating, start understanding!
Most AI labs today are fixated on generation. But before generating, you must understand; and most AI models today only scratch the surface when it comes to true clinical understanding. No more!
Since my PhD, I’ve pursued a vision: an AI map of healthcare, a digital atlas that grounds AI reasoning in structured medical knowledge, generalizing across ontologies, scientific literature, and all forms of clinical communication.
Two months after the public release of ClinicalEncoder25, an encoder that ingests clinical documents in milliseconds, extracting insights without secondary models for medical entity recognition or linking, I'm releasing today ClinicalEncoder26AM, its multilingual cousin. Whether you need highly expressive vector embeddings or ontology-grounded reasoning, ClinicalEncoder25 will deliver for your business!
The Diagnosable ColBERT: Interpretable by Design
Late-Interaction Retrieval, Reimagined
ClinicalEncoder26AM isn’t just another encoder. It performs late-interaction retrieval, clinical coding (UMLS, SnomedCT, or any other ontology), and topic extraction—all from the same representations. Unlike every other clinical encoder released before, this models knows that “PAPA Syndrome” is an X-linked interleukin-related deficiency, and can retrieve relevant PAPA documents even with generic queries like “interleukin deficiency,” no complex augmentation needed.
Hallucination-Free, Token-Level Reasoning
Unlike LLMs, ClinicalEncoder26AM represents entire documents in a single pass, in milliseconds, without generating tokens or hallucinating. It connects the dots: if a patient works at a car repair shop and is later noted to have lead contamination, the model infers “past history of exposure to lead-based paint,” augmenting its representation with all available evidence.
Unlike static tagging models, it can also accurately retreive concepts for which no individual entry exists in a predefined ontology, combining any number of pre-existing concepts freely to produce new, adhoc vector representations for any information the model reads (this can slightly lower interpretability, but means that retrieval doesn't have to suffer from limited ontologies).
Diagnosable by Design
Traditional ColBERT models are interpretable only in hindsight. ClinicalEncoder26AM changes that with its Diagnosable ColBERT architecture: every token is directly interpretable, mapped to a semantic clinical graph.
You can verify what the model understands immediately, without search queries, both at the mention level (“ranitidine”) and at the global semantic level (“no known allergy to ranitidine”).

What’s Next?
More supported languages are coming soon, in Q2 2026; the aim is to cover every European language properly. Get in touch if there are languages that you care about particularly!
End-to-end APIs and LLM Integration are also planned for Q2 2026; these offerings will let you go faster by combining multiple signals to produce high quality and traceable structured records for the clinical documents.
