Definition
Phi, short for ‘Foundation models based on Teaching-Learning Paradigm’, is a family of compact large language models created by Microsoft. Unlike traditional LLMs trained on massive web corpora, Phi models are trained on high-quality synthetic text derived from trusted sources. They demonstrate exceptional reasoning capabilities relative to their size, making them suitable for resource-constrained environments and applications requiring precise logical inference without the overhead of larger models.
