これは何か
Phi is a family of small language models introduced by Microsoft Research in June 2023. Its emphasis is data quality rather than model size: training on filtered “textbook-quality” text lets a few-billion-parameter model approach much larger ones on reasoning and coding. Phi-3 offers 3.8B, 7B and 14B sizes, and the smallest, Phi-3-mini, can run on-device. The models are released as open weights and are often used to probe the capability limits of small models.
なぜ覚えておく価値があるか
It showed that curating and orchestrating data can substitute for parameter count to a surprising degree: a few-billion-parameter model trained on selected data can approach models an order of magnitude larger on some reasoning tasks.
