Sana by Nvidia

Generate high-quality images from text prompts using Nvidia's Sana model. Supports classifier-free guidance, PAG guidance, and configurable resolution.

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": "sana",
    "version": "0.0.1",
    "input": {
      "prompt": "a cyberpunk cat with a neon sign that says Sana",
      "width": 1024,
      "height": 1024,
      "num_inference_steps": 18,
      "guidance_scale": 5
    }
  }'

Parameters

Parameter	Type	Default	Description
guidance_scale	number	5	Classifier-free guidance scale
height	integer	1024	Height of output image
negative_prompt	string	-	Specify things to not see in the output
num_inference_steps	integer	18	Number of denoising steps
pag_guidance_scale	number	2	PAG Guidance scale
prompt	string	a cyberpunk cat with a neon sign...	Input prompt
seed	integer	-	Random seed. Leave blank to randomize
width	integer	1024	Width of output image
