Microsoft Unveils Phi-4, a Small AI Model Excelling in Complex Reasoning

The 14-billion-parameter Phi-4 outperforms larger competitors in mathematical benchmarks while prioritizing efficiency and safety.

Phi-4 is a 14-billion-parameter small language model designed for advanced reasoning tasks, particularly in mathematics and problem-solving.
Microsoft claims Phi-4 surpasses larger models like Google’s Gemini Pro 1.5 in mathematical reasoning benchmarks, including AMC competitions.
The model leverages high-quality synthetic datasets, extended context lengths, and post-training techniques to enhance performance and efficiency.
Phi-4 is currently available under a research license on Azure AI Foundry, with plans for wider availability on Hugging Face next week.
Microsoft emphasizes safety features, including content filtering and real-time monitoring tools, to support responsible AI deployment.
