The challenge of rendering accurate text in AI-generated images has long been one of the most persistent obstacles in generative AI. While models have become increasingly sophisticated at generating photorealistic scenes, faces, and objects, text rendering—especially for non-Latin scripts like Chinese—has remained notoriously difficult. Today, we’re excited to announce that LongCat-Image, Meituan’s groundbreaking 6B parameter bilingual text-to-image model, is now available on WaveSpeedAI with instant inference and zero cold starts.
What is LongCat-Image?
LongCat-Image is a pioneering open-source foundation model developed by Meituan, one of China’s largest technology companies. What makes this model exceptional isn’t just its capabilities—it’s the efficiency with which it delivers them. With only 6 billion parameters, LongCat-Image consistently outperforms models that are 2-4 times larger, including competitors like Qwen-Image-20B and HunyuanImage-3.0 (80B parameters).
The model is built on a hybrid Multimodal Diffusion Transformer (MM-DiT) architecture similar to FLUX, but optimized for bilingual text understanding. It uses Qwen2.5-VL-7B as its text and vision-language encoder, with a clever hybrid approach to text handling: it processes overall prompts semantically while switching to a character-level tokenizer for text within quotation marks. This ensures accurate letter-by-letter rendering rather than the garbled approximations typical of other models.
Key Features
Industry-Leading Chinese Text Rendering
LongCat-Image achieves a ChineseWord score of 90.7, significantly outperforming all evaluated open-source models. It covers all 8,105 standard Chinese characters with superior accuracy and stability in rendering complex stroke structures—a feat no other model has matched.
Exceptional English Text Accuracy
The bilingual capabilities extend equally to English text rendering. Whether you need marketing slogans, product labels, or social media copy embedded in your images, LongCat-Image delivers crisp, accurate text without the spelling errors and distortions common in other models.
Remarkable Photorealism
Through an innovative data strategy and training framework, the model achieves photorealistic image quality that rivals much larger competitors. According to T2I-CoreBench results, LongCat-Image ranks second among all open-source models in comprehensive performance, surpassed only by the 32B-parameter Flux2.dev.
Impressive Benchmark Performance
- GenEval Score: 0.87 (matching state-of-the-art models)
- DPG-Bench: 86.8 (competitive with top closed-source solutions)
- ChineseWord: 90.7 (open-source SOTA)
Resource-Efficient Design
The compact 6B parameter architecture keeps GPU usage moderate, making it ideal for high-volume generation workflows and cost-sensitive production pipelines. You get enterprise-grade results without enterprise-grade infrastructure requirements.
Real-World Use Cases
Marketing and Advertising
Create professional marketing materials with embedded text in Chinese, English, or both languages simultaneously. Generate campaign posters, social media cards, and advertising banners with accurate typography in a single prompt—no more random strokes or distorted glyphs.
E-Commerce Product Visualization
Generate product images with accurate labels, descriptions, and promotional text. The model’s precise text rendering is particularly valuable for coupons, price tags, and on-product labeling that needs to be pixel-perfect.
Multilingual Campaign Assets
For businesses operating across Asian and Western markets, LongCat-Image eliminates the need to generate separate assets for different regions. Create consistent visuals with localized text for global campaigns in one unified workflow.
Social Media Content Creation
Lay out social cards, banners, and story graphics with bilingual text overlays. The model maintains visual consistency while handling the complex rendering requirements of mixed-language content.
Media and Localization
Generate marketing visuals that work across languages and regions without re-shooting or extensive post-production. Update existing marketing materials with new text through the companion LongCat-Image-Edit model while preserving the original composition.
