Microsoft open-sources multimodal reasoning model with 15B parameters

2026-03-04 20:21:51 ET

Microsoft Corp. today released a hardware-efficient reasoning model, Phi-4-reasoning-vision-15B, that can process multimodal files such as scientific charts. The model is based on two existing algorithms called SigLIP-2 and Phi-4 Reasoning. SigLIP-2 compresses images into a numerical form that neural networks can understand. Phi-4 Reasoning, in turn, is a reasoning model that Microsoft open-sourced last […]
