Hidiffusion

A training-free method that increases the resolution and speed of pretrained diffusion models.

Tip

Supports sdxl and sd1.5 text2image, image2image controlnet and inpainting
Use with DDIMScheduler

SDXL example usage and results. To use with any other sd1.5 or sdxl endpoint just add the param "hidiffusion": true

JSON Parameters

Parameter	Permissible values	Notes
model_id	`str`	model_id can be found in models page. Filter by SD-1.5 or SDXL models
prompt	`str, 75 tokens`	Check our Prompt Guide for tips
negative_prompt	`str, 75 tokens`	Check our Prompt Guide for tips
num_inference_steps	`int, [1-100]`	Noise is removed with each step, resulting in a higher-quality image over time. Ideal value 20-30
samples	`int, [1-4]`	Generates a maximum of 4 samples per API call
guidance_scale	`float, [1-20]`	Higher guidance scale prioritizes text prompt relevance but sacrifices image quality. Ideal value 7.5-12.5
width	`int`	Width in pixels. Lower than or equal to 1024 for best results
height	`int`	Height in pixels. Lower than or equal to 1024 for best results
hidiffusion	`bool`	Set to true for better image quality and faster inference
