Phi-4

Phi-4 is Microsoft's December 2024 successor to Phi-3 — a 14B-parameter small language model that demonstrated frontier-class reasoning capability through aggressive use of synthetic training data. Performance benchmarks showed Phi-4 competitive with much larger models (Llama 3.1 70B, Mistral Large) on math, reasoning, and coding tasks. The model's training relied heavily on carefully curated synthetic data generated by larger teacher models — refining the "textbook quality" data approach pioneered in earlier Phi generations. Phi-4 supports a 16K-token context window, function calling, and strong code generation. Available on Hugging Face and Azure AI under permissive licensing. Real-world deployments include the small-but-capable variant of Microsoft Copilot for resource-constrained scenarios, embedded AI features, and on-prem deployments where larger models are impractical. The Phi family has become foundational to Microsoft's small-model strategy and to on-device AI scenarios broadly. AI governance, AI compliance, and AI risk management programs deploy Phi-4 for cost-efficient reasoning supporting responsible AI in enterprise AI environments at scale.
