Description
phi-4
is a state-of-the-art open model built upon a blend of synthetic datasets, data from filtered public domain websites, and acquired academic books and Q&A datasets. The goal of this approach was to ensure that small capable models were trained with data focused on high quality and advanced reasoning.
phi-4
underwent a rigorous enhancement and alignment process, incorporating both supervised fine-tuning and direct preference optimization to ensure precise instruction adherence and robust safety measures

model quality
to understand the capabilities, we (here refer to microsoft side) compare
phi-4
with a set of models over OpenAI’s SimpleEval benchmark; at the high-level overview of the model quality on representative benchmarks; for the table below, higher numbers indicate better performance:
