Microsoft has announced the newest addition to its Phi family of generative AI models: Phi-4. It's in limited research preview.

The new small language model prioritizes efficiency and reasoning capabilities, leveraging Microsoft's focus on responsible AI development.

The new model has 14 billion parameters with improved performance in mathematical reasoning. Microsoft attributes Phi-4's improved performance to the use of high-quality synthetic datasets alongside human-generated content, as well as unspecified post-training improvements.

Microsoft has launched Phi-4, a small language model with 14 billion parameters, excelling in complex reasoning and math tasks. It outperforms larger models like Gemini Pro 1.5, thanks to high-quality datasets and innovative techniques,
