Overview

About this model

Flux-2-Klein-4B Edit with LoRA performs instruction-based image edits while applying custom LoRA adapters. It preserves the original scene's layout and lighting while pushing the result toward a specific style, character, or look defined by your LoRA. This makes it well-suited for stylized object swaps, costume changes, and look-conditioned edits where consistency with a brand or character LoRA matters.

You can pass 1 to 3 reference images plus an editing prompt, and stack up to 3 LoRA adapters per request. The 4B base keeps cost and latency low, which is ideal for high-volume editorial pipelines and rapid creative iteration.

How to Use Flux-2-Klein-4B Edit with LoRA

  1. Provide reference images: Pass 1 to 3 image URLs in images_list to edit.

  2. Write an editing instruction: Describe the change you want in prompt. Keep the change targeted so the original layout and lighting are preserved.

  3. Attach LoRAs: Provide up to 3 entries in lora_list, each with a path and scale.

  4. Choose an aspect ratio: Use aspect_ratio to control output framing.

  5. Submit and iterate: Call flux-2-klein-4b-edit-lora. Adjust LoRA scale or sharpen the prompt if the edit is too weak or too strong and re-run.

Common Questions

Frequently asked

How many reference images can I provide?

Between 1 and 3 reference images per edit request, passed in `images_list`.

Will the edit preserve identity / pose?

Klein Edit aims to preserve the original scene's layout and lighting. Identity preservation is best when your prompt targets specific elements (clothing, background, accessories) rather than rebuilding the subject.

Can I use the same LoRA workflow for both edit and text-to-image?

Yes. The `lora_list` schema is identical across the text-to-image and edit endpoints, so the same adapter weights and `scale` settings transfer cleanly between them.
