Features

HiDream I1 Full

HiDream I1 Full is a powerful text-to-image generation model that creates high-quality, photorealistic images from text descriptions. With flexible resolution control and excellent prompt adherence, generate stunning visuals for any creative project.

Why It Stands Out

High-quality generation: Produces detailed, photorealistic images with excellent clarity.
Prompt Enhancer: Built-in AI-powered prompt optimization for better results.
Flexible resolution: Customize width and height independently for any aspect ratio.
Multiple output formats: Export as JPEG or PNG based on your needs.
Affordable pricing: High-quality image generation at just $0.024 per image.
Reproducibility: Use the seed parameter to recreate exact results.

Parameters

Parameter	Required	Description
prompt	Yes	Text description of the image you want to generate.
width	No	Output width in pixels (default: 1024).
height	No	Output height in pixels (default: 1024).
seed	No	Set for reproducibility; -1 for random.
output_format	No	Output format: jpeg or png (default: jpeg).
enable_base64_output	No	Return base64 string instead of URL (API only).

How to Use

Write a prompt describing the image you want. Use the Prompt Enhancer for AI-assisted optimization.
Set dimensions — adjust width and height for your desired output size and aspect ratio.
Set a seed (optional) for reproducible results.
Select output format — choose JPEG or PNG.
Click Run and download your image.

Best Use Cases

Portrait Photography — Generate photorealistic portraits with natural lighting.
Product Visualization — Create product concepts and lifestyle imagery.
Marketing & Social Media — Produce eye-catching visuals for campaigns and posts.
Concept Art — Visualize ideas quickly before full production.
Creative Projects — Generate unique images for personal and commercial use.

Per image	$0.024

Pro Tips for Best Quality

Be detailed in your prompt — include subject, style, lighting, mood, and technical details.
Use photographic keywords like “Canon lens,” “depth of field,” “soft morning light.”
Specify color tones like “warm tones,” “cool tones,” or specific color palettes.
Adjust dimensions to match your intended use case and platform.
Fix the seed when iterating to compare different prompt variations.

Notes

Processing time varies based on resolution and current queue load.
Please ensure your prompts comply with content guidelines.
