WaveSpeedAI is thrilled to announce the availability of LongCat-Image Edit, a groundbreaking 6B parameter image editing model from Meituan that redefines what’s possible with bilingual text rendering and photorealistic image modifications. This model represents a significant leap forward in AI-powered image editing, particularly for applications requiring seamless Chinese and English text integration.
What is LongCat-Image Edit?
LongCat-Image Edit is part of Meituan’s LongCat family of visual AI models, specifically engineered for instruction-based image editing. Unlike traditional image editing tools that require masks, layers, or complex workflows, LongCat-Image Edit understands natural language commands in both Chinese and English, allowing you to describe the changes you want and watch them materialize with remarkable precision.
The model employs a sophisticated hybrid MM-DiT and Single-DiT architecture, leveraging Qwen2.5VL-7B as its text encoder and FLUX.1-dev’s VAE implementation. This combination delivers exceptional results while maintaining a remarkably efficient 6B parameter footprint—substantially smaller than competing models that often exceed 20B parameters while delivering comparable or inferior results.
Key Features
Exceptional Text Rendering Accuracy
LongCat-Image Edit sets a new industry standard for Chinese character rendering in images. On the ChineseWord Benchmark, the model achieves:
- 98.7% accuracy on L1 (common) characters
- 90.8% accuracy on L2 (intermediate) characters
- 70.3% accuracy on L3 (complex/rare) characters
- 90.7% overall accuracy—dramatically outperforming Qwen-Image (56.6%) and Seedream 4.0 (58.5%)
This superior Chinese text rendering capability makes LongCat-Image Edit the go-to solution for marketing materials, product packaging, and any visual content requiring accurate Chinese typography.
Natural Language Editing
Simply describe your desired changes in plain English or Chinese. Want to change the text on a product label? Modify the style of a banner? Add new elements while preserving the original composition? LongCat-Image Edit interprets your instructions and executes precise modifications without requiring manual masking or layer manipulation.
Bilingual Excellence
The model natively supports both Chinese and English prompts with equal proficiency. Whether you’re working with Western audiences or creating content for Chinese markets, you can seamlessly switch between languages or even combine them in a single project.
Photorealistic Output
Through an innovative data strategy and multi-stage training framework, LongCat-Image Edit produces remarkably photorealistic results. Human evaluations confirm the model achieves superior visual consistency compared to open-source competitors including Qwen-Image-Edit and FLUX.1 Kontext.
Deployment Efficiency
With only 6B parameters, LongCat-Image Edit requires significantly fewer computational resources than competing models, making it ideal for production deployments where cost and latency matter.
Benchmark Performance
LongCat-Image Edit has demonstrated state-of-the-art performance among open-source models across multiple evaluation benchmarks:
- ImgEdit-Bench: Overall score of 4.50 (highest among tested models)
- CEdit-Bench: Semantic consistency score of 8.27, perceptual quality of 7.88
- GEdit-Bench: Leading performance with overall score of 7.64
