How to Use Flux-2-Klein-4B Text-to-Image with LoRA

  1. Write your prompt: Describe the subject, scene, and mood. Keep prompts focused so the LoRA's style can lead the look.

  2. Pick LoRA adapters: Provide up to 3 LoRA entries in lora_list, each with a path (URL or path to the LoRA weights) and a scale (typically 0.5 - 1.5).

  3. Choose an aspect ratio: Pick from 1:1, 16:9, 9:16, 3:4, 4:3, 21:9, or 9:21 to control the framing.

  4. Submit and review: Send the request to flux-2-klein-4b-text-to-image-lora. The result returns asynchronously as an image URL. Tweak scale if the LoRA effect is too weak or too strong and re-run.

Common Questions

Frequently asked

How many LoRAs can I apply at once?

Up to three LoRA adapters per request via the `lora_list` field. Each entry has a `path` and a `scale` weight.

What is the recommended LoRA scale?

A `scale` of 1.0 is the typical default. Use 0.5 - 0.8 to soften the LoRA's influence or 1.1 - 1.5 to push it more strongly. Values above ~1.5 often degrade quality.

Where can I host my LoRA weights?

Any publicly reachable HTTPS URL works (e.g. Hugging Face, Civitai, S3). The `path` field accepts a direct download URL to the LoRA file.

What is the difference between the 4B and 9B LoRA variants?

The 4B variant is lighter and cheaper, ideal for high-volume stylized generation. The 9B variant trades cost for higher fidelity, lighting, and detail when you need premium output.
