1 credit per image
LongCat Image renders crisp Chinese and English text inside images, with photoreal lighting and flexible sizes from 256 to 1536 px — ideal for marketing, e-commerce, and research visuals.
Key Features of LongCat Image
Efficiency, bilingual typography, photorealism, and production-ready quality in one model family.
Exceptional Efficiency at 6B Scale
LongCat-Image delivers strong results without the footprint of 10B+ models. The compact architecture lowers VRAM pressure, shortens iteration cycles, and keeps per-image economics predictable—ideal for high-volume generation in SaaS products and automated marketing pipelines.
Powerful Chinese Text Rendering
Industry-leading coverage for Chinese characters inside images means signage, subtitles, packaging, and poster titles stay legible. The model reduces broken strokes and wrong glyphs compared with many general-purpose diffusion checkpoints, which is critical for Greater China campaigns and bilingual brand assets.
Remarkable Photorealism
Innovative data strategy and training frameworks produce skin texture, food photography, product highlights, and environmental lighting that hold up under zoom. Portrait, commercial, and lifestyle prompts benefit from natural depth of field and material response without excessive plastic smoothing.
Native Bilingual Prompting
Write prompts in English, Chinese, or a mix of both. LongCat-Image understands cultural context for neon street scenes, festival posters, academic slides, and Western-style product shots—so one model serves global teams instead of maintaining separate pipelines per language.
Flexible Size & Format Controls
Support common aspect ratios (1:1, 16:9, 9:16, 4:3, 3:4, and more) with width and height typically adjustable within a 256–1536 px range. Export to familiar formats for web, print previews, and downstream editing in Figma, Photoshop, or your own canvas tools.
Ready for Production Workloads
Generate on demand with predictable turnaround, reproducible seeds, optional safety checks, and credit-based pricing that scales with your team. Built for marketing ops, creative studios, and product teams that need reliable quality at volume—not one-off experiments.

Why Choose LongCat Image
Built for teams who need legible bilingual text, predictable costs, and workflows that scale.
Readable Text Inside Images
Marketing and education teams routinely need correct spelling in posters, slides, and packaging. LongCat Image prioritizes glyph accuracy in both Latin and Chinese scripts, reducing costly manual retouching.
Lower Cost per Asset
A 6B footprint means more images per GPU hour. For SaaS billing models priced per generation, that translates into healthier margins while still delivering premium-looking outputs.
Open Ecosystem & Extensibility
As an open foundation model, LongCat-Image invites fine-tuning, LoRA adapters, and community tooling. Vendors can differentiate with style packs, brand-safe filters, and vertical templates on top of a shared core.
Built for Real Workflows
From prompt enhancers to seed locking and batch-friendly generation, the workflow mirrors how professionals actually work: iterate, compare variants, approve one hero image, then push to ads, storefronts, or papers.
How to Use LongCat Image
From prompt to export in three steps—built for creators, marketers, and product teams alike.
Write Your Prompt
Describe subject, style, lighting, and any text that must appear in the image. Use English, Chinese, or both. Enable prompt enhancement if you want the system to expand short ideas into richer scene descriptions—especially useful for posters and academic figures.
Choose Size & Settings
Pick aspect ratio and resolution (e.g., 1024×1024 for square social posts, 16:9 for hero banners). Lock a seed when you want repeatable results, choose PNG or JPEG, and turn safety checks on or off to match your brand guidelines.
Generate, Review & Export
Generate in the workspace, review the result, and download when you are happy. Upscale if needed, then bring the asset into Figma, Photoshop, or your CMS. Teams on credit-based plans can track usage and keep a library of past generations in Profile.

What Users Say About LongCat Image
Teams across marketing, SaaS, research, and entertainment rely on LongCat Image for production-ready visuals.
We localized twelve campaign posters into Chinese without a retouch team. LongCat Image kept product labels and promo copy sharp—something our old SD workflow mangled every time.
The 6B footprint let us colocate image gen on the same GPUs as other services. Generation times stay predictable and our per-credit economics finally make sense at scale.
For supplementary figures and grant slide decks, we prompt diagram-style layouts with readable labels. Reviewers commented that visuals looked professionally designed.
Food photography prompts nail steam, condensation, and shallow depth of field. We spin hundreds of menu hero images for seasonal promos without studio rentals.
Environment concepts with ruined cities and overgrown skyscrapers matched our art direction brief on the first pass. Iteration is fast enough for daily standups.
Course thumbnails and slide heroes used to be stock photos. Now each module gets custom bilingual graphics that match the lesson topic and stay on brand.
