LongCat-Image - LongCat team open source image generation and editing model of the Mission

What is LongCat-Image?

LongCat-Image is an open source image generation and editing model released by the LongCat team of Meituan. Adopting hybrid backbone architecture (MM-DiT+Single-DiT), combined with visual language model (VLM) conditional encoder, it can realize text-generated image and multi-round image editing functions. In terms of image editing, it supports 15 types of tasks, such as object addition and style migration, to maintain image style and lighting consistency. With powerful Chinese text rendering capability, it can handle standard Chinese characters, rare characters and some calligraphy fonts, and can automatically adjust fonts and typography according to the scene. With its lightweight structure and optimized training strategy, LongCat-Image can efficiently reason on consumer GPUs to generate "studio-level" detailed images. In terms of performance, LongCat-Image reaches the open source SOTA level in several image editing benchmarks, and excels in Chinese text generation and text-to-map tasks. The resources have been open-sourced to Hugging Face and GitHub for developers to use.

Features of LongCat-Image

• Powerful Vincennes charts : It can generate high-quality images based on text prompts entered by the user to meet diversified creative needs.
• Multi-round image editing : It supports multiple rounds of image editing through natural language commands, covering 15 types of editing tasks such as object addition/removal, style migration, background replacement, text modification, etc. It maintains the consistency of the image style and lighting during the editing process, which makes the image editing more flexible and precise.
• Comprehensive coverage of Chinese characters : It can handle standard Chinese characters, rare characters and some calligraphy fonts, realizing full-volume and accurate coverage of commonly used characters and rare characters, and providing powerful support for Chinese image creation.
• Intelligent Typographic Adjustment : It can automatically adjust fonts, sizes and typography according to specific scenes, making the text more natural and beautiful in the image and enhancing the overall visual effect of the image.
• Efficient Reasoning LongCat - Image can achieve efficient inference on consumer GPUs by lightweighting the model structure and optimizing the training strategy, lowering the threshold of use and making it easy for ordinary users to start image generation and editing.
• High quality output The images generated have "studio-level" detail and can be used in applications that require high image quality, providing excellent visual effects for both artistic creation and commercial design.

LongCat-Image's Core Advantages

• Integrated generation and editing: It supports generating images through text prompts and multi-round editing of images through natural language commands, including 15 types of editing tasks such as object addition/removal, style migration, background replacement, text modification, etc., which can maintain the consistency of the image style and illumination in multi-round editing.
• Chinese text rendering capability: It can handle standard Chinese characters, rare characters and some calligraphy fonts, and can automatically adjust fonts, size and typography according to the scene. The generalization ability is improved by learning the glyphs in the pre-training phase and by introducing real-world text image data in the subsequent training.
• Output efficiency and qualityThe model structure is lightweight and the training strategy is optimized to enable efficient inference on consumer GPUs and generate images with "studio-grade" detail.
