Flux Dev

Generate high-quality images from text prompts using Flux Dev. Supports text-to-image and image-to-image modes with configurable aspect ratio, guidance, and quality settings.

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": "flux-dev",
    "version": "0.0.1",
    "input": {
      "prompt": "a photorealistic portrait of a woman in a sunlit garden, shallow depth of field, golden hour",
      "aspect_ratio": "4:5",
      "guidance": 3.5,
      "num_inference_steps": 28,
      "output_format": "webp"
    }
  }'

Parameters

Parameter	Type	Default	Description
aspect_ratio	string	1:1	Output aspect ratio. enum: 1:1, 16:9, 21:9, 2:3, 3:2, 4:5, 5:4, 9:16, 9:21
disable_safety_checker	boolean	false	Disable safety checker for generated images
guidance	number	3.5	Guidance for generated image
image	string	-	Input image for image-to-image mode
num_inference_steps	integer	28	Number of denoising steps. Recommended range is 28-50
num_outputs	integer	1	Number of outputs to generate
output_format	string	webp	Output format. enum: webp, png, jpg
output_quality	integer	80	Quality when saving output images, from 0 to 100
prompt	string	-	Prompt for generated image
prompt_strength	number	0.8	Prompt strength when using img2img. 1.0 is full destruction of input
seed	integer	-	Random seed. Set for reproducible generation
