Microsoft debuts Phi-4, a new generative AI model, in research preview
Microsoft has announced the newest addition to its Phi family of generative AI models.
Called Phi-4, the model is improved in several areas over its predecessors, Microsoft claims — in particular math problem solving. That’s partly the result of improved training data quality.
Phi-4 is available in very limited access as of Thursday night: only on Microsoft’s recently launched Azure AI Foundry development platform, and only for research purposes under a Microsoft research license agreement.
Notably, Phi-4 is the first Phi-series model to launch following the departure of Sébastien Bubeck. Bubeck, previously an AI VP at Microsoft and a key figure in the company’s Phi model development, left Microsoft in October to join OpenAI.
