Apache 2.0 — Microsoft's compact model for edge and local deployment. ## At a Glance **Where Phi-4 Mini leads** - 88.6% GSM8K — excellent math for a compact model - 83.7% ARC-C — strong commonsense reasoning - 64.0% MATH — solid competition math - Apache 2.0 — fully open - Optimised for low-resource deployment (mobile, edge) **Where it lags** - 32.8% Arena Hard — lower instruction following quality - 52.8% MMLU-Pro — limited academic breadth - 69.1% HellaSwag — moderate language understanding - Small model: limited capacity vs Phi-4 (14B) **Best for:** Edge deployment and local inference; mobile applications requiring math/reasoning; on-device code assistance. ## What Phi-4 Mini Is Phi-4 Mini is Microsoft's February 2025 compact model — the small sibling of Phi-4 (14B). The Phi series is known for "small data, big training" philosophy: Microsoft invests heavily in curated, high-quality training data to achieve strong reasoning in small models. Phi-4 Mini follows this pattern: 88.6% GSM8K at compact size is strong for the era, reflecting focused math training. The 64.0% MATH score is particularly high for a mini-class model. Apache 2.0 makes it freely deployable for commercial use. ## Specifications | Field | Value | |---|---| | Organization | Microsoft | | License | Apache 2.0 | | HuggingFace | microsoft/Phi-4-mini-instruct | | Release date | February 4, 2025 | | Modality | Text only | ## Pricing Open weights under Apache 2.0 — self-host at no cost.
