Image Generation

Quick Start

from litellm import image_generation
import os

# set api keys
os.environ["OPENAI_API_KEY"] = ""

response = image_generation(prompt="A cute baby sea otter", model="dall-e-3")

print(f"response: {response}")

Input Params for litellm.image_generation()

Required Fields

  • prompt: string - A text description of the desired image(s).

api_base: Optional[str] = None,
api_version: Optional[str] = None,
litellm_logging_obj=None,
custom_llm_provider=None,
  • model: string (optional) The model to use for image generation. Defaults to openai/dall-e-2

  • n: int (optional) The number of images to generate. Must be between 1 and 10. For dall-e-3, only n=1 is supported.

  • quality: string (optional) The quality of the image that will be generated. hd creates images with finer details and greater consistency across the image. This param is only supported for dall-e-3.

  • response_format: string (optional) The format in which the generated images are returned. Must be one of url or b64_json.

  • size: string (optional) The size of the generated images. Must be one of 256x256, 512x512, or 1024x1024 for dall-e-2. Must be one of 1024x1024, 1792x1024, or 1024x1792 for dall-e-3 models.

  • timeout: integer - The maximum time, in seconds, to wait for the API to respond. Defaults to 600 seconds (10 minutes).

  • user: string (optional) A unique identifier representing your end-user,

  • api_base: string (optional) - The api endpoint you want to call the model with

  • api_version: string (optional) - (Azure-specific) the api version for the call

  • api_key: string (optional) - The API key to authenticate and authorize requests. If not provided, the default API key is used.

  • api_type: string (optional) - The type of API to use.

OpenAI Image Generation Models

Usage

from litellm import image_generation
import os
os.environ['OPENAI_API_KEY'] = ""
response = image_generation(model='dall-e-2', prompt="cute baby otter")
Model NameFunction CallRequired OS Variables

Azure OpenAI Image Generation Models

API keys

This can be set as env variables or passed as params to litellm.image_generation()

import os
os.environ['AZURE_API_KEY'] =
os.environ['AZURE_API_BASE'] =
os.environ['AZURE_API_VERSION'] =

Usage

from litellm import embedding
response = embedding(
model="azure/<your deployment name>",
prompt="cute baby otter",
api_key=api_key,
api_base=api_base,
api_version=api_version,
)
print(response)
Model NameFunction Call
dall-e-2image_generation(model="azure/<your deployment name>", prompt="cute baby otter")
dall-e-3image_generation(model="azure/<your deployment name>", prompt="cute baby otter")

OpenAI Compatible Image Generation Models

Use this for calling /image_generation endpoints on OpenAI Compatible Servers, example https://github.com/xorbitsai/inference

Note add openai/ prefix to model so litellm knows to route to OpenAI

Usage

from litellm import image_generation
response = image_generation(
model = "openai/<your-llm-name>", # add `openai/` prefix to model so litellm knows to route to OpenAI
api_base="http://0.0.0.0:8000/" # set API Base of your Custom OpenAI Endpoint
prompt="cute baby otter"
)

Bedrock - Stable Diffusion

Use this for stable diffusion on bedrock

Usage

import os
from litellm import image_generation

os.environ["AWS_ACCESS_KEY_ID"] = ""
os.environ["AWS_SECRET_ACCESS_KEY"] = ""
os.environ["AWS_REGION_NAME"] = ""

response = image_generation(
prompt="A cute baby sea otter",
model="bedrock/stability.stable-diffusion-xl-v0",
)
print(f"response: {response}")
