Microsoft Releases Phi‑4‑Reasoning‑Vision‑15B on Foundry and Hugging Face

The 15B‑parameter model adds prompt‑controlled multi‑step reasoning to high‑resolution visual perception.

White line icons against a blue-green gradient background form an architecture flow chart. In the middle of the chart is a three-by-three matrix of circles and lines within a round-edge square. Above the matrix, three icons in a row – an equation, a person using a desktop, and a head with gears flow by dotted lines to the matrix. To the left of the matrix is an icon representing a stack of files with an arrow pointing to the matrix. To the right of the matrix is a graph with a double headed arrow pointing to the matrix and to itself. Below the matrix is an icon representing a document. A dotted line arrow connects this graph to the matrix, showing the direction flowing from the matrix to the document. To the right of the document icon is an hourglass icon and three list icons with a dotted line connecting the hourglass to the lists.

Overview

  • Developers can access the model now through Microsoft Foundry and Hugging Face with sample notebooks, API examples, a model card, and a technical paper.
  • The system offers three selectable thinking modes—hybrid, think, and nothink—letting teams balance deeper reasoning against lower latency during runtime.
  • Targeted uses include computer‑use agents that interpret UI screens and return actionable coordinates, as well as visual math, science, and document, chart, or table understanding.
  • Microsoft published internal benchmark results spanning multimodal reasoning, mathematics, and GUI tasks, presented as comparative analysis rather than formal leaderboard claims.
  • Safety alignment draws on public safety datasets and internally generated refusal examples under Microsoft’s Responsible AI principles, with documented limitations and deployment guidance.
