Phi 4

A 14-billion-parameter language model from Microsoft designed for general-purpose text generation and reasoning tasks with a 16K token context window.

Strengths

Delivers strong performance on reasoning and language understanding while maintaining reasonable inference speed for its parameter count.

Best for

General-purpose text generation, summarization, and reasoning tasks where model size and latency matter—superseded by Phi 4 Mini Instruct for resource-constrained deployments and by WizardLM-2 8x22B for tasks requiring extended context or expert-level reasoning.

Limitations

Limited to a 16K token context window, which is shorter than many contemporary models; instruction-tuning capabilities are more general compared to specialized variants like Phi 4 Mini Instruct.
