This study presents a comprehensive analysis and comparison of two predominant fine-tuning methodologies - full-parameter fine-tuning and parameter-efficient tuning - within the context of medical Large Language Models (LLMs). We developed and refined a series of LLMs, based on the Llama-2 architecture, specifically designed to enhance medical knowledge retrieval, reasoning, and question-answering capabilities. Our experiments systematically evaluate the effectiveness of these tuning strategies across various well-known medical benchmarks. Notably, our medical LLM Med42 showed an accuracy level of 72% on the US Medical Licensing Examination (USMLE) datasets, setting a new standard in performance for openly available medical LLMs. Through this comparative analysis, we aim to identify the most effective and efficient method for fine-tuning LLMs in the medical domain, thereby contributing significantly to the advancement of AI-driven healthcare applications.

  1. AdaThink-Med: Optimizing Inference-Time Compute for Medical Reasoning via Uncertainty Quantification

    cs.CL 2025-09 conditional novelty 6.0 of 10

    An entropy-guided reward that shortens answers to easy, confident questions and extends reasoning on hard ones reduces medical QA tokens by 4.7x to 6.4x with minimal accuracy loss.

  2. Automating Expert-Level Medical Reasoning Evaluation of Large Language Models

    cs.CL 2025-07 conditional novelty 6.0 of 10

    A benchmark with expert-annotated reasoning steps and an LLM judge that scores reasoning by step coverage, showing strong correlation with expert evaluation.

  3. Collaboration among Multiple Large Language Models for Medical Question Answering

    cs.CL 2025-05 conditional novelty 5.0 of 10

    An iterative collaboration framework where three LLMs exchange summarized reasoning on disagreed questions raises USMLE-style answer accuracy by 5.2 to 6.6 percentage points per model and raises consensus from 51% to 83%.

  4. Beyond Distillation: Pushing the Limits of Medical LLM Reasoning with Minimalist Rule-Based RL

    cs.CL 2025-05 conditional novelty 4.0 of 10

    Medical QA accuracy improves substantially through reinforcement learning with a binary correct-answer reward alone, without supervised fine-tuning on distilled reasoning traces.
