Eight Core Capabilities
From Image Generation to Creative Engine
Unlocking new visual creation experiences beyond traditional image generation
Precise Editing
Outstanding image editing performance with high-quality modifications through text prompts alone. Precisely executes add, delete, modify, and replace operations while maintaining overall image integrity. Perfect for advertising design, e-commerce retouching, and post-production, significantly reducing manual correction costs.
Flexible Reference
Finds the perfect balance between preservation and creation. Extracts key information from reference images like character identity, artistic style, or structural features, then recreates in entirely new contexts. Ideal for virtual avatar creation, derivative design, and secondary creation.
Visual Signal Control
Native integration of Canny, Depth, Mask and other visual signals without additional models. Users can guide image generation through simple sketches, doodles, or auxiliary lines. Essential for pose control, architectural design, and UI prototype generation.
In-Context Reasoning
Generation paradigm expanded from simple instruction execution to in-context reasoning generation. Understands physical and temporal constraints, 3D space, and complex contexts. Maintains style consistency and fine details in puzzles, crosswords, and comic continuations.
Multi-Image Reference
Supports up to a dozen reference images simultaneously, extracting character features, scene styles, and object structures for organic fusion. Perfect for virtual try-on or combining parts into complete mechanical structures while maintaining proper scale and physical coherence.
Multi-Image Output
Generates multiple images in one operation with global planning and contextual consistency. Creates coherent character sequences with unified style, perfect for storyboards, comic creation, and cohesive design sets like IP products or sticker packs.
Advanced Text Rendering
Breakthrough in text processing for generation models. Not only renders clear text correctly but also handles formulas, tables, chemical structures, and statistical charts. Produces high-knowledge-density content like educational courseware and academic illustrations.
Adaptive Ratio & 4K
Adaptive aspect ratio mechanism automatically adjusts canvas based on semantic needs or reference shapes. Supports custom sizing with resolution expanded to 4K ultra-high definition, achieving commercial application standards with more aesthetic compositions.
