Microsoft announced the latest addition to the Phi family of generative AI models.
Microsoft claims that this model, called Phi-4, is improved in several ways over previous versions, particularly in math problem solving. This is partly a result of improved training data quality.
Phi-4 is available with very limited access as of Thursday night. Available only on Microsoft's recently launched Azure AI Foundry development platform and for research purposes under the Microsoft Research License Agreement.
Notably, the Phi-4 is the first Phi series model to be launched after Sebastien Bubeck's retirement. Bubeck, who previously served as Microsoft's AI VP and was central to the development of the company's Phi model, left Microsoft to join OpenAI in October.
