Microsoft has introduced Phi-4, a compact AI language model with 14 billion parameters, designed for efficient mathematical problem-solving. It outperforms both similar-sized and larger models, including Gemini Pro 1.5, thanks to advanced training methods and high-quality datasets. Phi-4 aims to reduce computational costs and energy demands, making it accessible for resource-constrained organizations. Currently available via Azure AI Foundry, a broader release on Hugging Face is anticipated soon, featuring safety measures for responsible use.
