cogvlm is a powerful open-source visual language model (VLM) developed by the team at Tsinghua University. Compared to similar visual-language models like cogvlm and llava-13b, cogvlm stands out with its state-of-the-art performance on a wide range of cross-modal benchmarks, including NoCaps, Flickr30k captioning, and various visual question answering tasks. The model has 10 billion visual parameters and 7 billion language parameters, allowing it to understand and generate detailed descriptions of images. Unlike some previous VLMs that struggled with hallucination, cogvlm is known for its ability to provide accurate and factual information about the visual content. Model Inputs and Outputs Inputs Image**: An image in a standard image format (e.g. JPEG, PNG) provided as a URL. Prompt**: A text prompt describing the task or question to be answered about the image. Outputs Output**: An array of strings, where each string represents the model's response to the provided prompt and image. Capabilities cogvlm excels at a variety of visual understanding and reasoning tasks. It can provide detailed descriptions of images, answer complex visual questions, and even perform visual grounding - identifying and localizing specific objects or elements in an image based on a textual description. For example, when shown an image of a park scene and asked "Can you describe what you see in the image?", cogvlm might respond with a detailed paragraph capturing the key elements, such as the lush green grass, the winding gravel path, the trees in the distance, and the clear blue sky overhead. Similarly, if presented with an image of a kitchen and the prompt "Where is the microwave located in the image?", cogvlm would be able to identify the microwave's location and provide the precise bounding box coordinates. What Can I Use It For? The broad capabilities of cogvlm make it a versatile tool for a wide range of applications. Developers and researchers could leverage the model for tasks such as: Automated image captioning and visual question answering for media or educational content Visual interface agents that can understand and interact with graphical user interfaces Multimodal search and retrieval systems that can match images to relevant textual information Visual data analysis and reporting, where the model can extract insights from visual data By tapping into cogvlm's powerful visual understanding, these applications can offer more natural and intuitive experiences for users. Things to Try One interesting way to explore cogvlm's capabilities is to try various types of visual prompts and see how the model responds. For example, you could provide complex scenes with multiple objects and ask the model to identify and localize specific elements.
