Capable of Deciding When to Think on Its Own! Microsoft Releases Phi-4 15B Open-Source Model, Focused on Miniaturization and Multimodal Capabilities
Microsoft releases the open-source multimodal large model Phi-4-reasoning-vision-15B, which has 15 billion parameters. Its core breakthrough is the ability to autonomously assess task difficulty and intelligently choose between rapid response or in-depth reasoning, a rare feature in lightweight open-source models. The model specializes in high-difficulty tasks such as image description, interface element localization, and complex mathematical reasoning.
