AI Image Generator — Create from Text or Photo
The Trellis 3D AI image generator lets you create professional AI images from a text prompt or an uploaded photo — no design skills required. Switch between text-to-image mode for generating scenes from scratch and image-to-image mode for transforming, editing, or reimagining existing photos. Powered by GPT Image 2 and GPT Image 1.5 from OpenAI, Seedream 5.0 and Seedream 4.5 from ByteDance, Flux 2 from Black Forest Labs, and Nano Banana 2 from Google, this AI image generator gives you multi-model flexibility in a single platform. Output in up to 4K resolution with no watermark and full commercial rights.
Choose Your AI Image Model
Six industry-leading AI models, each built for a different creative goal. Pick by output quality, generation speed, or how many reference photos you need.
GPT Image 1.5
OpenAI · Best for text in images
The go-to model when your image needs readable text, accurate logos, or precise typography. GPT Image 1.5 follows complex instructions with exceptional accuracy and supports up to 16 reference images for detailed multi-element compositions.
Seedream 4.5
ByteDance · 4K artistic output
Built for artistic output at 4K resolution. Seedream 4.5 excels at rich visual styles, anime aesthetics, and detailed illustrations. Strong at interpreting stylistic references and delivering images with exceptional depth and color.
Seedream 5.0
ByteDance · Chain-of-thought reasoning
ByteDance's newest model with chain-of-thought reasoning — it thinks through your prompt before generating, resulting in more accurate interpretations of complex scenes. Outputs at 3K resolution with stronger semantic understanding.
Flux 2 Pro
Black Forest Labs · Fastest generation
The fastest model in the lineup. Flux 2 Pro delivers sharp, photorealistic images optimized for speed — ideal when you need to iterate quickly or generate at volume without sacrificing output quality.
Nano Banana
Google · Character consistency
Google's character-consistent image model. Exceptionally good at keeping subjects recognizable across multiple generations — useful for brand mascots, recurring characters, and product shots that need visual continuity.
Nano Banana 2
Google · Google Search grounding
The most capable model for complex briefs. Nano Banana 2 supports Google Search grounding for real-world accuracy, handles up to 14 reference images, and outputs at 4K with 15 aspect ratio options including ultra-wide and portrait extremes.
Text to Image and Image to Image — One Platform
Most AI image tools force you to choose one mode. Trellis 3D gives you both on the same page. Start from a text prompt when you're building something from scratch — describe the scene, mood, style, and lighting, and the AI generates it. Switch to image-to-image mode when you already have a photo: upload it as a reference, describe your changes, and the AI transforms, extends, or reimagines it. Both modes share the same model lineup, the same 4K output quality, and the same no-watermark download.
What Can You Create with an AI Image Generator?
From product mockups to concept art — the AI image generator adapts to your workflow, not the other way around.
Product Photography
Professional catalog shots without a studio
Upload a plain product photo and use image-to-image AI to generate lifestyle shots, swap backgrounds, or place it in a scene. Works for e-commerce listings, Amazon images, and brand campaigns.
Social Media Visuals
On-brand content at posting speed
Generate scroll-stopping images for Instagram, TikTok, Pinterest, and YouTube. Create consistent visual styles across posts without a designer — describe the aesthetic once, generate at scale.
Marketing Campaigns
Ad creatives and campaign visuals in minutes
Turn a text brief into campaign-ready images for ads, landing pages, and email headers. Use reference images to maintain brand consistency across every asset in a campaign.
Character & Concept Art
From brief to reference sheet in seconds
Generate character designs, mood boards, and concept art for games, animation, and illustration projects. Use Nano Banana 2 for subject consistency across multiple reference angles.
AI Image Prompt Examples for Real-World Use
Copy, adapt, and test these prompts across different models. Each one is optimized for a specific visual outcome.
E-Commerce Product Shot
Lifestyle product photography
"White sneaker on clean marble surface, soft studio lighting from upper left, subtle drop shadow, 4K commercial photography, pure white background, ultra-sharp detail, no background clutter"
Social Media Banner
Wide-format content creation
"Tokyo street at night, neon signs reflecting on wet pavement, 16:9 cinematic composition, Blade Runner color grade, bokeh background, ultra-wide establishing shot, vibrant and moody"
Character Reference Sheet
Game design and animation
"Female warrior in ornate silver armor, front and side view on white background, clean concept art style, professional character design sheet, detailed linework, consistent proportions"
Brand Lifestyle Scene
Campaign and editorial photography
"Minimalist coffee shop interior, warm golden hour window light, person reading at wooden table, lifestyle editorial style, shallow depth of field, Leica film photography aesthetic, muted warm tones"
How to Write Better AI Image Prompts
- • Be specific about style - Name the aesthetic directly: 'Leica film photography', 'Studio Ghibli illustration', 'Brutalist architecture rendering' — vague words like 'beautiful' give the AI nothing to work with
- • Describe lighting explicitly - Lighting changes everything: 'soft golden hour backlight', 'harsh studio strobe from left', 'overcast diffused light' — models respond better to named lighting setups than mood words
- • Use reference images for consistency - In image-to-image mode, upload your reference photo before writing the prompt — the AI uses it as a visual anchor, giving you far more control over the output
- • Match the model to the task - Seedream 5.0 for artistic depth, GPT Image 2 or GPT Image 1.5 for text or typography in images, Nano Banana 2 for character consistency across shots, Flux 2 when you need results fast
How to Generate AI Images Online
Two paths, same result: professional AI images in under 30 seconds.
Choose Text-to-Image or Image-to-Image
Starting from scratch? Use text-to-image — describe any scene and the AI builds it. Have an existing photo? Use image-to-image — upload it and describe how you want it changed.
Pick a Model and Write Your Prompt
Select the AI model that fits your goal: Seedream 5.0 for artistic styles, GPT Image 2 or GPT Image 1.5 for images with text, Nano Banana 2 for character consistency, Flux 2 for speed. Then write your prompt.
