Our verdict
Phi models are small enough to run on everyday hardware while staying capable at reasoning and maths, and the MIT licence keeps things simple. Phi-4-mini is compact, and the 14B Phi-4 fits on a mid-range GPU. Language coverage is narrower than some rivals; Hindi is not in Phi-4-mini's supported list.
