Introducing LongCat-Image API on Pixazo: High-Fidelity, Bilingual Text-to-Image & Editing for Production Workflows

We’re excited to introduce the LongCat-Image API on Pixazo — a powerful open-source, 6-billion-parameter model developed by Meituan’s LongCat team, now integrated into Pixazo’s standardized API framework. LongCat-Image is engineered for creators, designers, and developers who need photorealistic image generation, precise bilingual text rendering, and reliable, instruction-based image editing without heavy GPU requirements.

Unlike conventional text-to-image models that struggle with consistent structure or multilingual text, LongCat-Image brings a clean, production-ready approach to creative workflows. It offers the rare combination of sharp typography, layout control, high efficiency, and open-source transparency, making it ideal for UI designers, marketers, product teams, and anyone creating visual content at scale.

What Makes LongCat-Image a Breakthrough?

LongCat-Image stands out because it bridges a practical gap in generative imaging: accurate text + clean layouts + photorealistic visuals, all from a compact 6B model. While many larger models generate impressive visuals, few can place crisp English and Chinese text exactly where you want it — a critical requirement for e-commerce creatives, brand cards, posters, and marketing graphics.

The model’s architecture is optimized to outperform larger 20B+ systems in speed and efficiency, while maintaining competitive output quality. This means faster iteration cycles, lighter infrastructure requirements, and better affordability for teams shipping high-volume creative assets.

Built with the principles of scalability, accessibility, and community collaboration, LongCat-Image is fully open-sourced, including training toolchains and model weights. Pixazo brings this capability directly to creators and developers through a unified API experience, making it easier than ever to integrate high-precision image generation into your products and pipelines.

Core Capabilities of LongCat-Image

While the model supports a wide range of creative workflows, its standout abilities include:

1) Bilingual Text Rendering (Chinese + English)

LongCat-Image is specifically trained for accurate, clean, and stable text placement within images — a rarity in current image-generation models. Whether you're making interface screens, promo banners, or social media layouts, the typography remains sharp and readable.

2) High Efficiency Without Quality Loss

Despite being only 6B parameters, LongCat-Image rivals much larger models in photorealism and correctness. It runs efficiently on consumer-grade GPUs, enabling rapid iterations and affordable production.

3) Intelligent Image Editing

The “Edit” variant allows you to modify existing images through natural-language instructions, including:

• Object addition or removal
• Layout adjustments
• Attribute or style changes
• Maintaining lighting, structure, and composition

This makes it ideal for real-world content pipelines where you refine visuals rather than regenerate everything from scratch.

4) Open-Source Foundation

The entire training workflow is public, enabling developers, researchers, and enterprises to contribute, analyze, or extend the model for specialized use cases.

5) Designed for Professional Creative Output

From ad campaigns to UI assets, LongCat-Image excels in scenarios where clean spacing, readable text, and consistent visual identity matter.

What’s New on Pixazo?

With LongCat-Image now available, Pixazo’s creative toolkit gets several fresh capabilities that significantly broaden what creators and developers can build — beyond what existing models offer. Here’s what’s new:

• Dedicated text-aware image generation: Users can now reliably generate images containing sharp, clean English and Chinese text — ideal for posters, UI designs, social cards, banners, product labels, and more.
• Lightweight, efficient production-grade generation: Because LongCat-Image is only 6B parameters yet highly optimized, teams can run it even on modest GPU setups — enabling scalable production without high infrastructure cost.
• Natural-language image editing in a stable pipeline: Using simple text instructions, you can refine or alter generated or existing images — adding/removing objects, changing style or layout — while preserving structure, lighting, and composition.
• Open-source transparency and community-driven growth: With training code and model weights publicly available, LongCat-Image encourages collaboration, customization, and long-term trust.
• Seamless integration with existing Pixazo APIs: LongCat-Image follows the same request/response model as other Pixazo tools — making it straightforward to plug into existing image/video pipelines, SaaS platforms, or creative workflows.

This means that beyond cinematic video, character consistency, or multimodal editing (as with our other engines), Pixazo now supports clean, layout-aware, high-fidelity image work — rounding out the creative stack.

What You Can Build With LongCat-Image?

Whether you are a solo creator or building a SaaS platform, LongCat-Image unlocks workflows such as:

• High-quality UI component mockups
• E-commerce product cards with multilingual labels
• Social media creatives with crisp overlaid quotes
• Marketing banners and ad campaign assets
• Posters, flyers, and illustrated content with reliable text
• Photorealistic compositions with structured layouts
• Instruction-based edits for product photography and branding
• Poetic images with embedded Chinese or English captions

This model is built for professionals who care about typography fidelity, layout clarity, and creative consistency.

Why Pixel-Level Editing Matters?

Like our previous multimodal engines redefined video editing with natural-language control, LongCat-Image brings a similar philosophy to still images. Instead of relying on masks, layers, or manual Photoshop workflows, you describe the desired change — and the model applies it cleanly while preserving the integrity of the original composition.

This makes it especially powerful for iterative creative work where each revision needs to stay aligned with brand identity, lighting, subject positioning, and product accuracy.
