Azure Phi is Microsoft�s family of Small Language Models (SLMs) designed for efficient, low-latency natural language processing. While larger LLMs like GPT-4 focus on generalized intelligence, Phi targets domain-specific, lightweight inference ideal for edge deployment, real-time applications, and embedded AI. Developers can access Phi models through Azure AI Studio, allowing them to fine-tune, deploy, and scale applications with minimal compute resources. Phi is optimized for coding assistance, reasoning, summarization, and chat-style responses�offering fast, low-cost alternatives to large-scale AI models.
