Researchers have developed a method to adapt large language models for Brazilian healthcare by injecting knowledge from official clinical guidelines. They created a synthetic dataset of over 70 million tokens from 178 guidelines and fine-tuned a 14-billion parameter model, Qwen2.5-14B-Instruct. This adapted model achieved high scores on new benchmarks, HealthBench-BR and PCDT-QA, outperforming several leading commercial models despite its smaller size. The team has released the datasets, benchmarks, and model weights to foster further research in clinical NLP for Brazilian Portuguese. AI
