To optimize open-weight medical large language models as specialized diagnostic tools by evaluating context window scaling and multi-stage supervised fine-tuning within a localized retrieval-augmented generation framework.
Evaluated open-weight Llama-3.1-8B and Qwen2.5-14B-Instruct model architectures using the MedQA USMLE-style benchmark.
Integrated multi-stage supervised fine-tuning within a localized Retrieval-Augmented Generation (RAG) framework across varying context window lengths.
Quantified option-preference bias using Total Variation Distance and evaluated output length changes.
Identified a context scaling threshold at 512 tokens where diagnostic accuracy stabilized while maintaining computational efficiency.
Documented a brevity shift that decreased verbosity by over 99.7%, moving from an average of 465 tokens to single-token outputs for Qwen and near-single-token outputs for Llama.
Achieved peak diagnostic accuracy of 70.0% on MedQA with the Qwen architecture alongside reduced option-preference bias.
