Building open, on-device medical AI — OpenMed · Arcee AI · CNRS

I created OpenMed: open-source medical AI that runs where the data lives — locally, on a hospital's own servers or on edge devices like smartphones. 2,200+ Apache-2.0 models, 460M+ downloads on Hugging Face, 18M+ installs on PyPI, and 85 contributors so far — with zero paid marketing.

Alongside OpenMed, I work in post-training at Arcee AI — developing open-weight models in the U.S. and releasing them for everyone — and I run AI & HPC infrastructure at CNRS.

My stance hasn't changed: medical AI must be open, auditable, and sovereign — deployable inside a hospital's own walls, and increasingly on the phone in your pocket. Its limits belong in code: OpenMed ships refusal and review gates, not terms-of-service promises.

And it must be measured in the open: what ran, what it can do, where it failed, and what it still cannot claim. That is the standard I hold my own models to, and the one I'd hold any health model to.

OpenMed

Open-source clinical AI: 2,200+ Apache-2.0 models for de-identification, clinical NER, coding, and QA — built to run locally — on-prem, in your VPC, or on edge devices like smartphones. 460M+ downloads on Hugging Face, 5,000+ GitHub stars, and the #1 most-referenced organization in Hugging Face's State of Open Source report (Spring 2026).

  • openmed on GitHub — Python package, CLI, and on-device runtimes; near-weekly releases, 85 contributors
  • OpenMed on Hugging Face — the model hub
  • OpenMed NER — state of the art on 10 of 12 public biomedical NER datasets
  • OpenMed releases — multilingual PII across 42 language routes (35 model-backed), ~51 offline ID validators, and a k-anonymity release-risk workflow that refuses to auto-sign expert determinations

Next: OpenMed's own reasoning models — on-device, local-first — and multimodality across X-ray, pathology, and medical speech-to-text.

OpenMed Agent

A clinical AI agent built on OpenMed's open models — terminal-native, inspectable, privacy-first, reviewer-gated, and running on-device on smartphones. Early access is open at agent.openmed.life.

Welna

Know your numbers. Own your health story. Welna is my consumer iOS app, powered by OpenMed: it reads your Apple Health data, redacts identifiers on-device, and preps you for your next doctor's visit — your name, dates, and IDs never leave the phone.

About

I've spent 16 years in public academia: twelve at CNRS, where I'm a lifetime civil servant and run the AI & HPC infrastructure at ISC-PIF (140+ servers, 380B+ documents), after research-assistant and cloud-architect years at Multimedia University and the University of Malaya.

Before OpenMed, from 2019 to 2025, I was at John Snow Labs leading Spark NLP — 150M+ downloads and 100,000+ pretrained models and pipelines. Since 2024 I've also been in post-training at Arcee AI: GRPO, RL environments, and the INTELLECT-1 and Trinity technical reports.

What hasn't moved: medical AI should be open, auditable, and able to run inside a hospital's own walls — with the models, the training, and their limits out in the open. The longer version is on LinkedIn.
