Microsoft: Phi 4

Microsoft Phi-4, a 14-billion parameter model created on January 9, 2025, demonstrates a strong overall performance profile, particularly excelling in efficiency and reliability. It performs among the fastest models, ranking in the 63rd percentile for speed, and consistently offers highly competitive pricing, placing in the 85th percentile. Notably, Phi-4 exhibits exceptional reliability with a 100% success rate across all benchmarks, indicating minimal technical failures and consistent provision of usable responses. In terms of specific benchmark performance, Phi-4 achieved perfect accuracy in the Ethics (Baseline) test, making it the most accurate model at its price point and among models of comparable speed. It also showed strong performance in Hallucinations (Baseline) with 96.0% accuracy, effectively acknowledging uncertainty. While its General Knowledge (Baseline) accuracy was respectable at 96.8%, its performance in Email Classification (94.0% accuracy) and especially Reasoning (50.0% accuracy) suggests areas for improvement. Its strength lies in ethical reasoning and avoiding factual errors, while complex reasoning tasks present a notable weakness. Designed for complex reasoning and efficient operation in limited memory scenarios, Phi-4 is best suited for English language inputs.
