Microsoft's Phi-4 AI Models Deliver Big Performance in Small Packages

Microsoft has unveiled its latest Phi-4 AI models—Phi-4 Mini Reasoning, Phi-4 Reasoning, and Phi-4 Reasoning Plus—designed to offer high-level reasoning capabilities in compact forms. Despite having significantly fewer parameters, these models rival the performance of much larger systems. Phi-4 Reasoning Plus, for instance, approaches the capabilities of DeepSeek's 671-billion-parameter R1 model. Trained on curated datasets, including synthetic math problems and OpenAI's o3-mini demonstrations.
