Step1x Edit

Step1x Edit

Playground

Step1X-Edit converts photos into professional-quality edits using simple instructions, rivaling top proprietary tools. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

Step1X Edit is a powerful AI-powered image editing model that modifies images based on simple text instructions. Describe what you want to change — hair color, clothing, background, objects — and the model applies precise, targeted edits while preserving the rest of the image.

Why It Stands Out

• Instruction-based editing: Edit images using natural language commands.
• Precise modifications: Changes only what you specify, preserving everything else.
• Prompt Enhancer: Built-in AI-powered prompt optimization for better results.
• Negative prompt support: Exclude unwanted elements for cleaner outputs.
• Fine-tuned control: Adjust guidance scale and inference steps for precise results.
• Affordable pricing: High-quality edits at just $0.03 per image.
• Reproducibility: Use the seed parameter to recreate exact results.

Parameters

How to Use

1. Upload your image — drag and drop a file or paste a public URL.
2. Write an editing instruction describing what you want to change. Use the Prompt Enhancer for AI-assisted optimization.
3. Add a negative prompt (optional) — specify elements to exclude.
4. Adjust parameters (optional) — fine-tune guidance scale and inference steps.
5. Click Run and download your edited image.

Example Instructions

• “Change hair color to red”
• “Add sunglasses”
• “Change the background to a beach”
• “Make the dress blue”
• “Remove the hat”
• “Add a smile”
• “Change season to winter”

Best Use Cases

• Portrait Retouching — Change hair color, add accessories, modify expressions.
• Fashion & E-commerce — Swap clothing colors, add or remove items.
• Background Editing — Change environments and settings.
• Creative Projects — Experiment with visual variations quickly.
• Content Creation — Generate multiple versions of images for A/B testing.

Pro Tips for Best Quality

• Use clear, specific instructions — “Change hair color to red” works better than “Make it different.”
• Keep instructions focused on one or two changes at a time.
• Use negative prompts to prevent unwanted side effects.
• Lower guidance scale (2–4) for subtle changes, higher (5–7) for more dramatic edits.
• Fix the seed when iterating to compare different instructions on the same base.

Notes

• Ensure uploaded image URLs are publicly accessible.
• Processing time varies based on current queue load.
• Please ensure your content complies with usage guidelines.
