Writing Effective Prompts for UNI-1

UNI-1's reasoning engine understands complex, natural-language instructions. Unlike other models that require terse keyword prompts, UNI-1 benefits from descriptive, detailed descriptions.

Recommended Prompt Structure

[Subject] + [Environment/Context] + [Style] + [Lighting] + [Mood/Atmosphere]
Weak Prompt

"cat in forest"

Strong Prompt

"A tabby cat sitting on a mossy log in an ancient forest at golden hour, soft dappled light filtering through oak leaves, painterly impressionist style, warm amber tones, peaceful and serene mood"

Useful Prompt Templates

  • Portrait: "Professional headshot of [person description], studio lighting, [background], photorealistic, 4K detail"
  • Product: "[Product] on [surface], [environment] background, commercial photography, clean and minimal"
  • Fantasy: "[Character/Scene], epic fantasy art style, dramatic lighting, highly detailed, concept art for [game/film type]"
  • Architecture: "[Building type] exterior, [architectural style], [time of day], [weather], architectural visualization render"

Image Generation with UNI-1

UNI-1 supports both text-to-image and image-to-image generation. The model outputs at up to 2K resolution with precise prompt adherence.

Text-to-Image

Describe your vision in natural language and UNI-1 renders it. Works with complex multi-element scenes that trip up other models.

Style Control

Choose from 76+ built-in art styles — from photorealism to anime, oil painting to pixel art. Mix styles with weighted modifiers.

Resolution

Output at standard (512×512), HD (1024×1024), or 2K (2048×2048). Higher resolutions use more credits but deliver professional-grade detail.

Multi-turn Image Editing

UNI-1's most powerful feature is conversational editing — the ability to refine your image through follow-up messages, just like chatting with a designer.

Example Editing Conversation

You:"A woman standing in a modern kitchen, morning light"
UNI-1:[Generates image]
You:"Change the countertops to marble and add a coffee machine on the left"
UNI-1:[Updates exactly those elements, preserving everything else]
You:"Make the lighting warmer and add steam rising from a coffee mug"
UNI-1:[Adds atmospheric details while maintaining the scene]

Key advantage: UNI-1 remembers the full conversation context, so each edit builds on the previous state without losing coherence or restarting from scratch.

Advanced UNI-1 Techniques

Complex Scene Composition

Use spatial modifiers to control element placement: "in the foreground", "behind", "to the left of", "partially obscured by". UNI-1 handles up to 8 distinct objects with accurate spatial relationships.

Multi-image Combination

Upload 2–4 reference images and describe how to combine them. UNI-1 can merge styles, characters, and environments from multiple inputs into a single coherent output.

76+ Art Style Application

Specify styles precisely: "in the style of Claude Monet", "ukiyo-e woodblock print", "brutalist architectural rendering", or "cyberpunk concept art". Combine two styles with weighted syntax: "80% photorealistic, 20% watercolor".

Best Practices & Tips

Be specific about lighting

Lighting dramatically affects output quality. Always specify: golden hour, soft studio, harsh midday, candlelight, etc.

Use negative prompts sparingly

UNI-1 understands exclusions naturally. Write "without shadows" rather than adding a separate negative prompt.

Iterate in small steps

For complex edits, make one change at a time in multi-turn mode. Large single-step changes may cause unintended drift.

Leverage aspect ratio

Specify orientation for better composition: "portrait orientation", "wide cinematic crop", "square format for social media".

Name the camera

Add "photographed with a 50mm lens", "aerial drone shot", or "macro close-up" to control perspective and depth of field.

Reference real art movements

UNI-1 has extensive art history knowledge. "Art Deco poster style" or "Bauhaus geometric design" yields more precise style application than generic descriptors.
