Phi-2 by Microsoft

Phi-2 is a small language model developed by Microsoft that demonstrates strong performance despite its compact size. Rather than requiring vast computational resources like larger models, Phi-2 achieves capable natural language processing through efficient architecture and training methods. This makes it practical for organisations with limited hardware budgets or those needing faster inference times. The model is particularly notable for challenging the assumption that AI performance scales directly with model size; Microsoft's research shows Phi-2 can handle reasoning tasks, code generation, and text understanding effectively. It's designed for developers and researchers who need functional language model capabilities without deploying enormous computational infrastructure.
