Microsoft has introduced Phi-4, the latest in its Phi series of generative AI models, available for limited research use on the Azure AI Foundry platform. This 14 billion parameter model excels in math problem-solving due to improved training data quality, including high-quality synthetic datasets. Phi-4 competes with other small models like GPT-4o mini and Claude 3.5 Haiku, offering faster and cheaper performance. The launch follows the departure of key developer Sébastien Bubeck to OpenAI.
