GLM-4.5V processes images and video frames through a unified vision-language encoder that maintains temporal coherence across sequential frames. The model uses a Mixture-of-Experts architecture where only 12B of 106B parameters activate per inference, routing visual tokens and text through specialized expert layers for efficient multi-modal fusion. This enables understanding of spatial relationships, object tracking, and temporal dynamics within video sequences without requiring separate video preprocessing pipelines.
Unique: Uses sparse Mixture-of-Experts routing (12B active from 106B total) specifically optimized for video temporal understanding, enabling efficient processing of sequential visual frames while maintaining state-of-the-art accuracy on video benchmarks — most competitors use dense architectures or separate video encoders
vs alternatives: Outperforms GPT-4V and Claude 3.5V on video understanding tasks while using sparse activation for lower latency, and provides better temporal reasoning than image-only vision models through native video sequence handling
GLM-4.5V generates natural language descriptions of images by encoding visual features through its vision encoder and decoding them via the language model head. The model produces detailed captions that go beyond object detection to include spatial relationships, actions, attributes, and contextual understanding. The MoE architecture allows selective activation of language generation experts based on caption complexity, optimizing for both brevity and detail depending on prompt instructions.
Unique: Integrates vision encoding and language generation through a unified MoE backbone rather than separate encoder-decoder modules, allowing dynamic expert selection based on image complexity and caption requirements — enables more efficient processing than two-stage pipelines
vs alternatives: Produces more contextually rich captions than BLIP-2 or LLaVA while maintaining lower latency than GPT-4V through sparse activation, and supports longer, more detailed descriptions than typical image captioning models
GLM-4.5V answers natural language questions about image content through a visual grounding mechanism that maps text tokens to image regions. The model maintains conversation context across multiple turns, allowing follow-up questions that reference previous answers or ask for clarification. The MoE architecture routes question-answering experts based on query complexity, enabling efficient handling of both simple factual questions and complex reasoning tasks requiring multi-step inference.
Unique: Maintains multi-turn conversation state within a single model forward pass using attention mechanisms that bind visual tokens to dialogue history, rather than requiring separate context management or re-encoding images per turn — reduces latency for follow-up questions
vs alternatives: Supports longer multi-turn conversations than LLaVA or BLIP-2 while maintaining visual grounding, and provides more natural dialogue flow than GPT-4V due to native conversation optimization in the training objective
GLM-4.5V analyzes documents, tables, charts, and infographics by recognizing layout structure, text hierarchy, and visual elements. The model extracts structured information (tables, key-value pairs, hierarchies) and can convert visual data representations (charts, graphs) into textual or JSON formats. The vision encoder is optimized for document-specific patterns like text alignment, column detection, and chart type recognition, enabling accurate extraction without OCR preprocessing.
Unique: Combines visual layout understanding with semantic extraction in a single forward pass, recognizing document structure (columns, sections, tables) natively rather than relying on post-hoc OCR + NLP pipelines — enables accurate extraction from complex layouts without preprocessing
vs alternatives: More accurate than traditional OCR + regex extraction on structured documents, and handles layout-dependent information better than text-only LLMs, though less specialized than dedicated document AI services like AWS Textract
GLM-4.5V identifies objects within images and reasons about their spatial relationships, sizes, positions, and interactions. The model can count objects, describe relative positions ('left of', 'above', 'overlapping'), and infer relationships based on visual proximity or context. The vision encoder produces spatially-aware embeddings that enable the language model to ground references to specific image regions, supporting queries like 'How many people are standing to the left of the tree?'
Unique: Performs object detection and spatial reasoning jointly through the language model rather than using separate detection heads, enabling semantic understanding of relationships that pure detection models cannot capture — allows reasoning about 'the person holding the umbrella' rather than just detecting persons and umbrellas
vs alternatives: Provides richer semantic understanding of object relationships than YOLO or Faster R-CNN, and enables spatial reasoning that image-only models like CLIP cannot perform, though less precise than specialized object detection models for bounding box accuracy
GLM-4.5V can generate images from text descriptions by leveraging its vision-language understanding to ground concepts in visual space. The model uses its learned visual representations to synthesize images that match textual specifications, guided by the same multimodal embeddings used for understanding. The MoE architecture allows selective activation of generation experts based on prompt complexity, enabling efficient synthesis of both simple and complex visual concepts.
Unique: Grounds text-to-image generation in the same multimodal embedding space used for vision-language understanding, enabling semantically coherent generation that respects visual relationships learned from understanding tasks — differs from diffusion-based models that learn generation independently
vs alternatives: Provides more semantically coherent images than DALL-E for complex multi-object scenes due to joint vision-language training, though typically lower visual quality than specialized diffusion models like Stable Diffusion or Midjourney
GLM-4.5V computes similarity between images and text by projecting both into a shared embedding space learned during multimodal training. The model can rank images by relevance to text queries, find similar images to a reference image, or match text descriptions to visual content. The unified embedding space enables efficient retrieval without separate encoding passes, leveraging the MoE architecture to route similarity computation through specialized experts.
Unique: Performs cross-modal retrieval through a unified MoE embedding space rather than separate image and text encoders, enabling direct similarity computation without alignment layers — reduces latency and improves semantic coherence compared to two-tower architectures
vs alternatives: More semantically accurate than CLIP for domain-specific image-text matching due to larger model capacity, though requires more computational resources for embedding generation and may be slower than optimized retrieval systems like FAISS with pre-computed embeddings
GLM-4.5V can produce step-by-step reasoning about visual content, breaking down complex image understanding tasks into intermediate reasoning steps. The model generates explicit chains of thought that explain how it arrived at conclusions about images, enabling transparency and verification of visual reasoning. The language model component naturally supports this through its training on reasoning tasks, while the vision encoder grounds each reasoning step in visual evidence.
Unique: Generates visual reasoning chains natively through the language model component while maintaining visual grounding, rather than using post-hoc explanation techniques — enables reasoning that is grounded in actual visual features rather than model internals
vs alternatives: Provides more transparent reasoning than black-box vision models, and produces more visually-grounded explanations than text-only reasoning models, though less formally verifiable than symbolic reasoning systems

Stable Diffusion utilizes a latent diffusion model to generate high-quality images from textual descriptions. It first encodes the input text into a latent space using a transformer architecture, then progressively refines a random noise image into a coherent image that matches the text prompt through a series of denoising steps. This approach allows for fine control over the image generation process, enabling diverse outputs from the same input prompt.
Unique: Stable Diffusion's use of a latent space for image generation allows for faster and more memory-efficient processing compared to pixel-space models, enabling the generation of high-resolution images without the need for extensive computational resources.
vs alternatives: More efficient than DALL-E for generating high-resolution images due to its latent diffusion approach, which reduces memory usage and speeds up the generation process.
Stable Diffusion supports image inpainting, which allows users to modify existing images by specifying areas to be altered and providing a new text prompt. This capability leverages the model's understanding of context and content to seamlessly blend the new elements into the original image, maintaining visual coherence. It uses masked regions in the image to guide the generation process, ensuring that the output respects the surrounding context.
Unique: The inpainting feature is integrated into the same diffusion process as the text-to-image generation, allowing for a unified model that can handle both tasks without needing separate architectures.
vs alternatives: More flexible than traditional inpainting tools because it can generate entirely new content based on textual prompts rather than relying solely on existing image data.
Stable Diffusion can perform style transfer by applying the artistic style of one image to the content of another. This is achieved by encoding both the content and style images into the latent space and then blending them according to user-defined parameters. The model then reconstructs an image that retains the content of the original while adopting the stylistic features of the reference image, allowing for creative reinterpretations of existing works.
Stable Diffusion scores higher at 39/100 vs Z.ai: GLM 4.5V at 22/100.
