MEDITRON is an AI model designed to help doctors and healthcare professionals make better decisions by providing access to medical knowledge. It was trained on high-quality medical information from research papers and guidelines. Unlike other medical AI models that are closed-source, MEDITRON's code and training data are open, allowing transparency and further improvement by researchers. The goal is to safely bring the benefits of AI to healthcare in an ethical way.

MEDITRON is a pair of open-source large language models (LLMs) with 7 and 70 billion parameters, tailored to the medical domain. It was trained on carefully curated medical data sources, including peer-reviewed literature and clinical practice guidelines. MEDITRON outperforms other open-source models and closed models like GPT-3.5 on medical benchmarks, coming within 5-10% of GPT-4 and Med-PaLM-2.
