Deep Architectural Overview

GLM-4.5V introduced thinking mode to visual reasoning. Supporting video frame sequences, high-resolution document OCR, and GUI interaction bounding boxes, it serves as a foundation for autonomous desktop and mobile agents.

Strengths & Considerations

Core Strengths
  • 100B open-weights vision model
  • Native GUI agent support and visual grounding
  • Integrated visual thinking mode
Known Limitations
  • 64k context window; upgraded to 128k on GLM-4.6V
