The project’s leader says that allowing everyone to access the collection of public-domain books will help “level the playing field” in the AI industry.

Phi-4 is the fourth iteration of an open-source language model series Microsoft introduced last year. Its architecture is nearly identical to that of its predecessor, Phi-3-medium. Both neural networks feature 14 billion parameters and can process prompts with up to 4,000 tokens, units of data that each contain a few characters.

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

Microsoft’s Phi-4, a 14-billion-parameter AI model, excels at mathematical reasoning with fewer resources than larger models.

Microsoft on Wednesday denied claims that it uses customer data from its Microsoft 365 applications, including Word and Excel, to train artificial intelligence models. The response came after some users pointed out on social media that the company requires users to opt-out of its "connected experiences" feature,

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,

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