How to Use Our Uni-1
Four steps from concept to finished image. No design skills required.
Describe Your Vision
Type a detailed prompt into the Uni-1 image generator. Describe subjects, style, mood, and composition in natural language — the model’s multimodal reasoning handles the rest.
Upload References
Add up to 8 reference images for identity preservation, style matching, or pose guidance. Uni-1 grounds your output in the source material, not random interpolation.
Review and Refine
Uni-1 AI generates results in seconds. Use multi-turn refinement to adjust lighting, swap backgrounds, or tweak specific regions through follow-up prompts.
Download Your Image
Export at up to 2048px resolution. All files are auto-deleted within 1 hour — your creative assets stay private.
Pro Tip: When using reference images with Uni-1, include at least one full-body and one portrait shot. This gives the model enough identity context to maintain consistency across wildly different compositions and camera angles.
Key Features of Uni-1
A unified model that reasons, imagines, and creates — powered by a decoder-only autoregressive transformer.
Intelligent Reasoning
Uni-1 performs structured internal reasoning before and during image generation. It decomposes complex prompts, resolves spatial constraints, and plans composition — achieving state-of-the-art on the RISEBench visual editing benchmark.
Directable Generation
Guide output with reference images. The Uni-1 AI model preserves identity, style, and pose from up to 8 source images, giving you precise creative control without manual editing tools.
Culture-Aware Output
From Japanese manga conventions to Western cinematic framing, Uni-1 understands cultural visual languages. Generate memes, aesthetic photography, sports imagery, and editorial content that feels authentic — not generic.
Affordable at Scale
At approximately $0.09 per image (2048px), Uni-1 costs 10–30% less than comparable AI image models. Text input at $0.50/M tokens, image output at $45.45/M tokens — built for production workflows.
Multi-Turn Refinement
Describe follow-up adjustments in natural language. The Uni-1 image generator iterates on your previous output — adjusting lighting, swapping elements, or changing perspective without regenerating from scratch.
