yoDEV Decisions tool compares LLM performance on user data

yoDEV Decisions is a new free tool for yoDEV members that allows users to compare the performance of various Large Language Models (LLMs) against their own data. The tool runs the same query across selected LLMs and a model called Jev, evaluating accuracy, calibration, cost, and latency. Initial results show Jev to be faster and cheaper than popular LLMs like GPT-4o mini, Gemini 2.5 Flash, Claude Haiku-4-5, and Llama 3.3-70B, though its accuracy can lag in specific tasks like sentiment analysis in Spanish. yoDEV Decisions also offers a combined strategy where Jev handles most queries based on its confidence threshold, passing only complex cases to a chosen LLM, which can significantly improve efficiency and cost-effectiveness. AI

IMPACT Enables users to benchmark LLMs against their own data, optimizing for cost and performance in specific applications.
