Novita AI Text to Image API: Generate Stunning Visuals from Text with Stable Diffusion

Generate images from text prompts using Stable Diffusion models.

This is an asynchronous API; only the task_id will be returned. You should use the task_id to request the Task Result API to retrieve the image generation results.

Hide properties

model_name

string

required

This parameter specifies the name of the model checkpoint. Retrieve the corresponding sd_name value by invoking the Query Model API with filter.types=checkpoint as the query parameter.

prompt

string

required

Text input required to guide the image generation, divided by , . Range [1, 1024].

width

integer

required

Width of image. Range [128, 2048].

height

integer

required

Height of image. Range [128, 2048].

image_num

integer

required

Images numbers generated in one single generation. Range [1, 8].

steps

integer

required

The number of denoising steps. More steps usually can produce higher quality images, but take more time to generate, Range [1, 100].

guidance_scale

number

required

This setting says how close the Stable Diffusion will listen to your prompt, higer guidance forces the model to better follow the prompt, but result in lower quality output. Range [1, 30].

sampler_name

string

required

This parameter determines the denoising algorithm employed during the sampling phase of Stable Diffusion. Each option represents a distinct method by which the model incrementally generates new images. These algorithms differ significantly in their processing speed, output quality, and the specific characteristics of the images they generate, allowing users to tailor the image generation process to meet precise requirements. Get reference at A brief introduction to Sampler.Enum:

Euler a,Euler,LMS,Heun,DPM2,DPM2 a,DPM++ 2S a,DPM++ 2M,DPM++ SDE,DPM fast,DPM adaptive,LMS Karras,DPM2 Karras,DPM2 a Karras,DPM++ 2S a Karras,DPM++ 2M Karras,DPM++ SDE Karras,DDIM,PLMS,UniPC

negative_prompt

string

Text input that specifies what to exclude from the generated images, divided by , . Range [1, 1024].

sd_vae

string

VAE (Variational Auto Encoder). sd_vae can be accessed in the API /v3/models with query params type=vae, like sd_name: customVAE.safetensors. Get reference at A brief introduction to VAE.

seed

integer

A seed is a number from which Stable Diffusion generates noise, which, makes generation deterministic. Using the same seed and set of parameters will produce identical image each time, minimum -1. Defaults to -1.

loras

object[]

LoRA is a fast and lightweight training method that inserts and trains a significantly smaller number of parameters instead of all the model parameters. Currently supports up to 5 LoRAs.

Show properties

model_name

string

required

Name of lora, retrieve the corresponding sd_name_in_api value by invoking the Get Model API endpoint with filter.types=lora as the query parameter.

strength

number

required

The strength value of lora. The larger the value, the more biased the effect is towards lora, Range [0, 1]

embeddings

object[]

Textual Inversion is a training method for personalizing models by learning new text embeddings from a few example images, currently supports up to 5 embeddings.

Show properties

model_name

string

required

Name of textual Inversion model, you can call the Get Model API endpoint with parameter filter.types=textualinversion to retrieve the sd_name_in_api field as the model_name.

hires_fix

object

Upscale images while they are generating.

Show properties

target_width

integer

required

Target width, Range [128, 4096].

target_height

integer

required

Target height, Range [128, 4096].

strength

number

required

Defines the intensity of the upscaler model’s effect. A value of 0 means the upscaler has no effect, while 1 results in maximum intensity, fully utilizing the upscaler’s capabilities, range [0, 1].

upscaler

string

The upscaler model’s name.Enum: RealESRGAN_x4plus_anime_6B,RealESRNet_x4plus,Latent

refiner

object

SD refiner.

Show properties

switch_at

number

required

The switch_at parameter in the context of a refiner allows you to set the extent to which the refiner alters the output of a model. When set to 0, the refiner has no effect; at 1, it’s fully active. Intermediate values like 0.5 provide a balanced effect, where the refiner is moderately engaged, enhancing or adjusting the output without dominating the original model’s characteristics. This setting is particularly useful for fine-tuning the output to achieve a desired balance between refinement and the original generative features, Range [0, 1].

enable_transparent_background

bool

Make the resulting image’s background transparent. Please note that if the transparent_background is enabled, the extra response_image_type must be PNG, and only SDXL models are allowed.

restore_faces

bool

Used to control whether the Face Restoration feature is enabled.

Response

task_id

string

Use the task_id to request the Task Result API to retrieve the generated outputs.

nsfw_detection_result, presenting an array of NSFW detection outcomes for each image. The order of elements in the nsfw_detection_result array corresponds one-to-one with the sequence of images in the images field in the response. The valid field denotes the success of the NSFW detection process, while the confidence field, ranging from 0 to 100, signifies the confidence level of the NSFW detection result. Higher confidence values, nearing 100, suggest a greater likelihood of the corresponding image containing NSFW content.
