Fine-Tuning Small Open-Source LLMs to Outperform Large Closed-Source Models by 60% on Specialized Tasks

Parsed, in collaboration with Together AI, demonstrates how small open-source models can outperform large proprietary models on complex tasks, such as healthcare scribing, through task-specific optimization and comprehensive evaluation. By employing a rigorous evaluation-first methodology and fine-tuning models for specific tasks, Parsed achieves 60% better accuracy with 10 to 100 times lower inference costs compared to larger models. This approach allows for greater transparency and reliability, essential in domains like healthcare where precision is critical. Parsed's advanced evaluation harnesses align closely with expert judgment to ensure clinical soundness, source fidelity, and adherence to specific styles, enabling smaller models to exceed the performance of larger, general-purpose models. The partnership with Together AI provides a robust fine-tuning platform that supports continuous optimization and seamless deployment, allowing organizations to achieve superior performance and significant cost savings.
