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.

Phi-4 surpasses both similar-sized and larger models in mathematical problem-solving, including high-profile competitors including Gemini Pro 1.5

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,

The algorithm’s performance is notable mainly because of the way it was built: Microsoft trained Phi-4 mostly on synthetic, or machine-generated, data rather than web content as is the usual practice.

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,
