Phi-4

Phi-4 is a 14B parameter state-of-the-art small language model introduced by Microsoft, specializing in complex reasoning, particularly in areas such as math. It is designed for developers and organizations seeking to integrate advanced language processing capabilities into their applications. Phi-4 is part of the Phi family of small language models and is available on Azure AI Foundry and Hugging Face.

Phi-4 works by leveraging high-quality synthetic datasets, curated organic data, and post-training innovations to achieve high-quality results despite its relatively small size. It outperforms comparable and larger models on math-related reasoning tasks. Additionally, Phi-4 can be used with Azure AI Content Safety features such as prompt shields, protected material detection, and groundedness detection, which can be integrated into applications through a single API.

Developers and data scientists working on projects that require advanced mathematical reasoning or complex language processing will find Phi-4 particularly valuable. Its ability to excel in math problems and its availability on platforms like Azure AI Foundry and Hugging Face make it a versatile tool for a variety of use cases, from educational applications to research projects.
