Flux Lora

Generate images from text prompts using Black Forest Labs Flux with LoRA weights. Fine-tune output style with custom LoRA models and configurable guidance.

Quick Start

Requires an each::labs API key. Get one at eachlabs.ai.

curl -X POST https://api.eachlabs.ai/v1/prediction \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "model": "bfl-flux-lora",
    "version": "0.0.1",
    "input": {
      "prompt": "a beautiful mountain landscape at sunset, photorealistic",
      "loras": [{"path": "https://example.com/landscape-lora.safetensors", "scale": 0.8}],
      "image_size": "landscape_4_3",
      "guidance_scale": 3.5
    }
  }'

Parameters

Parameter	Type	Default	Description
enable_safety_checker	boolean	true	If set to true, the safety checker will be enabled.
guidance_scale	number	3.5	The CFG scale controls how closely the model follows the prompt.
