+- **Meditron-4: Clinical feedback alignment and SOTA dev**
+
+  Meditron-4 is the next iteration of Meditron, designed to close the gap between medical knowledge and guideline-faithful, clinically contextualized behavior. While Meditron-3 is now lagging behind state-of-the-art, Meditron-4 will deliver an open-source fine-tuning and evaluation pipeline and the best clinically aligned model we can produce on top of leading open medical and general base models—while also pushing small, offline-capable models (e.g., MedGemma 4B, LFM-2) for low-resource deployment.
