Flux 2 | Klein | 9B | Base | Text to Image

Generate high-quality images from text descriptions using the Flux 2 Klein 9B Base model. Supports various image sizes, guidance scales, and output formats.

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-2-klein-9b-base-text-to-image",
    "version": "0.0.1",
    "input": {
      "prompt": "A serene Japanese garden with cherry blossoms, koi pond, and wooden bridge at sunset",
      "image_size": "landscape_4_3",
      "num_inference_steps": 28,
      "guidance_scale": 5,
      "output_format": "png"
    }
  }'

Parameters

Parameter	Type	Default	Description
acceleration	string	regular	The acceleration level to use for image generation. Options: none, regular, high
enable_safety_checker	boolean	true	If set to true, the safety checker will be enabled.
guidance_scale	number	5	Guidance scale for classifier-free guidance.
image_size	string	landscape_4_3	The size of the image to generate. Options: square_hd, square, portrait_4_3, portrait_16_9, landscape_4_3, landscape_16_9
negative_prompt	string	-	Negative prompt for classifier-free guidance. Describes what to avoid in the image.
num_images	integer	1	The number of images to generate.
num_inference_steps	integer	28	The number of inference steps to perform.
output_format	string	png	The format of the generated image. Options: jpeg, png, webp
prompt	string	-	The prompt to generate an image from.
seed	integer	-	The seed to use for the generation. If not provided, a random seed will be used.
