Redefine creative edits with dual-input precision and adaptive control for design professionals
LongCat Image Edit is Meituan’s advanced image editing AI under the LongCat AI suite, purpose-built to extend their 6-billion-parameter LongCat-Image model into a powerful image-to-image generation system. Designed for bilingual use in Chinese and English, it delivers exceptional consistency, high fidelity, and semantic accuracy in every edit. This release introduces key upgrades like superior text rendering, layout and texture preservation, and fast inference optimized for creative professionals seeking precise, instruction-based transformations across multi-round editing workflows.
LongCat Image Edit image-to-image gives you full control to modify images naturally through language prompts, producing professional, studio-quality outputs without complex masking. The tool caters to creators, marketers, designers, and anyone needing perfect alignment of detail and realism. With LongCat Image Edit, you harness effortless, intelligent image-to-image generation that preserves integrity, enhances style, and achieves consistent, high-resolution results.
LongCat Image Edit is a high-fidelity image-to-image system optimized for precise, instruction-driven changes while preserving scene structure, lighting, and identity. Built for designers, LongCat Image Edit performs targeted updates rather than full-frame resynthesis, maintaining geometry and material response for realistic outcomes. With strong text rendering and style consistency, LongCat Image Edit keeps typography legible and perspective-aware. The model balances controllability and creativity, enabling subtle retouching or global restyling without drifting from the source image.
Key capabilities:
Provide a clear base image URL and a concise prompt specifying what to change and what to preserve. LongCat Image Edit responds best to concrete nouns, materials, and spatial qualifiers. Indicate global goals such as mood or style, and local scopes such as background only or keep subject untouched. Tune num_inference_steps for detail, guidance_scale for adherence, and seed for reproducibility. LongCat Image Edit supports output_format selection and acceleration settings for throughput. When iterating, LongCat Image Edit benefits from short, incremental refinements.
