How to Use Flux-2-Klein-9B Edit with LoRA

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

  2. Describe the edit: Write a focused prompt that targets specific elements to change while leaving the rest of the scene intact.

  3. Attach LoRAs: Add up to 3 LoRA adapters in lora_list, each with path and scale.

  4. Pick an aspect ratio: Set aspect_ratio to control framing.

  5. Submit and refine: Call flux-2-klein-9b-edit-lora. If the LoRA influence is too strong, lower its scale; if the edit doesn't go far enough, raise the scale or sharpen the prompt.

Common Questions

Frequently asked

When should I pick the 9B Edit variant over 4B?

Choose 9B Edit when you need higher detail retention, cleaner lighting, and stronger prompt adherence. Choose 4B Edit when cost and throughput matter more than per-image fidelity.

How many reference images can I provide?

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

Are the LoRA settings the same as the text-to-image variant?

Yes. The `lora_list` field uses the same `path` + `scale` schema, so the same adapters work on both the edit and text-to-image endpoints.
