phi-4-reasoning Local AI Setup

A lightweight open model focused on high-quality, reasoning-dense synthetic data.

How to Run phi-4-reasoning Locally

$ ollama run phi4-reasoning

Deployment Check

This model requires a specialized High-VRAM environment. Ensure you have the latest CUDA Drivers or Metal Framework installed.


Minimum VRAM: 11GB VRAM Recommended

Origins & History

The phi-4-reasoning model by Microsoft is a 14B parameter architecture optimized for reasoning tasks. It requires approximately 9GB of VRAM to comfortably run locally using a Q4_K_M quantization. Extending the context window up to 131,072 tokens will dynamically allocate further VRAM, meaning high-bandwidth memory hardware is strictly advised.

Pros

  • Full privacy and offline inference capabilities
  • Highly capable 14B parameter structure
  • Supports impressive 131,072 token context window

Cons

  • Requires 9GB+ VRAM minimum
  • Local inference speed depends entirely on memory bandwidth (GB/s)

Architect's Runtime Strategy

For running phi-4-reasoning at maximum tokens-per-second, we recommend using LM Studio or Ollama with a GGUF quantization (Q4_K_M or Q6_K). If you are multi-GPU, use vLLM to distribute the layers across your VRAM pool for optimal throughput.

Common Questions

What hardware do I need to run phi-4-reasoning?

You will need a GPU with at least 11GB of VRAM to run the Q4_K_M quantized version smoothly with a moderate context window.

How do I install phi-4-reasoning locally?

The simplest method is utilizing Ollama by executing 'ollama run phi4-reasoning' directly in your command line. Alternatively, you can search for the model via LM Studio's interface.
