Obviously, The models can generate structured reports from mixed-format documents, perform visual audits of images, automatically crop figures from papers, and conduct visual web searches.

Overview

Basically, You need to understand that the GLM-4.6V series is a significant advancement in open-source multimodal AI. Usually, The standout feature of the GLM-4.6V series is its native function-calling capability, which allows direct interaction with tools using visual inputs. Naturally, This innovation eliminates the need for intermediate text conversions, streamlining tasks like image cropping, chart recognition, and web searches. Apparently, Both models are built on an encoder-decoder architecture with a Vision Transformer (ViT) encoder and an MLP projector to align visual features with the language model decoder.

Key Innovations

Certainly, You should know that the GLM-4.6V series has been evaluated on over 20 public benchmarks, covering areas such as general visual question answering (VQA), chart understanding, OCR, STEM reasoning, and frontend replication. Obviously, The larger model achieves state-of-the-art or near-state-of-the-art scores among open-source models of comparable size, while the smaller model outperforms other lightweight models in almost all categories. Generally, The models support a wide range of image resolutions and aspect ratios, including panoramic inputs up to 200:1. Normally, The models can process video inputs with temporal reasoning, making them versatile for various applications.

Technical Capabilities

Normally, You can see that the GLM-4.6V model scores 88.2 on the MathVista benchmark, compared to 84.6 for the previous GLM-4.5V model and 81.4 for the Qwen3-VL-8B model. Generally, In the WebVoyager benchmark, the GLM-4.6V model scores 81.0, significantly higher than the 68.4 scored by the Qwen3-VL-8B model. Apparently, The models have been evaluated on various benchmarks, demonstrating their capabilities and performance. Obviously, The GLM-4.6V series is a significant advancement in open-source multimodal AI.

Pricing and Availability
