Microsoft Phi-4-reasoning-plus - AI Language Models Tool

Overview

Phi-4-reasoning-plus is an open-weight reasoning large language model from Microsoft, finetuned for advanced chain-of-thought reasoning. It uses a dense 14B-parameter decoder-only Transformer with a 32k-token context and produces chain-of-thought followed by a concise summarization.

Key Features

  • Open-weight reasoning LLM developed by Microsoft
  • Finetuned with chain-of-thought traces and reinforcement learning
  • Dense 14B-parameter decoder-only Transformer
  • 32k-token context length
  • Outputs chain-of-thought reasoning then a summarization
  • Optimized for math, science, and coding reasoning
  • Designed for constrained memory and low-latency settings
  • Hosted model page available on Hugging Face

Ideal Use Cases

  • Research into reasoning behavior and model fine-tuning
  • Solving advanced math and scientific reasoning tasks
  • Assisting with coding and program synthesis
