We build clinically grounded, auditable AI for medicine — co-designed and evaluated with clinicians, humanitarian responders, and data scientists worldwide. --- ## 🆕 Fully Open Meditron Our latest release, **Fully Open Meditron**, is the first end-to-end auditable pipeline for clinical LLMs — open weights, open data, open training recipe, and clinician-vetted corpus construction. **Apertus-70B-MeditronFO** establishes a new state of the art among fully open medical LLMs, and **Gemma-3-27B-MeditronFO** outperforms MedGemma on HealthBench Hard despite being trained from a fully open pipeline. 👉 Browse the [**MeditronFO Collection**](https://huggingface.co/collections/EPFLiGHT/meditronfo) — six models across three families (Apertus, OLMo-2, EuroLLM, Gemma-3), plus the [Fully Open Meditron Corpus](https://huggingface.co/datasets/EPFLiGHT/fully-open-meditron) (~601k clinician-audited examples). --- ## Previous Work - [**Meditron-3**](https://openreview.net/pdf?id=ZcD35zKujO) — open medical LLM suite spanning Llama-3, Phi-4, Qwen2.5, and Gemma-2 bases.
