SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Flux Kontext Pro helps you perform accurate, high-fidelity edits on a single source image without the prompt drifting the subject’s identity or details.

Core Features & Use Cases

  • Single-reference precise local image editing: Uses Flux 1 Kontext Pro for targeted edits driven by one declarative instruction.
  • High prompt control with identity preservation: Keeps the person/product framing, pose, and visual identity while changing only what you specify.
  • Right-model routing guidance: Use this for Kontext edits, and route to related siblings for multi-image edits or out-of-scope tasks like text-heavy or generate-from-scratch scenarios.
  • Deterministic variants via seed: Supports reproducible iterations by setting a seed.

Quick Start

Ask: "Keep the person's face, pose, and clothing unchanged and add an orange umbrella in her left hand and a slight smile" with your input image URL.

FAQPage Schema
How do I edit a single image without changing the subject's identity or pose?

To edit a single image without changing the subject's identity, use Flux 1 Kontext Pro for prompt-guided image-to-image editing. It preserves the original framing, pose, and visual identity while applying only the targeted modifications you specify.

Can I reproduce the exact same image edit multiple times using Flux?

Yes, you can reproduce identical image edit variants by setting a seed in your Flux request. This deterministic approach ensures that the same input image and prompt will generate reproducible iterations consistently.

What is the best way to add or swap objects in a product mockup?

The best way to add or swap objects in a product mockup is using single-reference image editing with Flux. You provide a declarative instruction to perform high-fidelity local edits while keeping the surrounding product context intact.

Does Flux Kontext support editing multiple images at once?

No, Flux Kontext does not support editing multiple images at once. It is specifically designed for precise single-image image-to-image edits, requiring exactly one source image to maintain high prompt control and identity preservation.

How do I perform photo retouching with prompt-guided instructions?

You perform photo retouching by passing a single source image and a declarative prompt to the Flux 1 Kontext Pro endpoint. This enables targeted changes like adjusting small details or adding objects while preserving the original photo's core identity.

When should I avoid using Flux Kontext for image generation?

You should avoid using Flux Kontext for generating images from scratch or handling text-heavy scenarios. It is specifically built for precise single-image editing tasks like object swapping and photo retouching, not generating entirely new visual content.
