"""This tool allows agents to generate images using Steamship.
|
|
|

Steamship offers access to different third party image generation APIs
|

using a single API key.
|
|
|
|
Today the following models are supported:
|
|
- Dall-E
|
|
- Stable Diffusion
|
|
|
|
To use this tool, you must first set as environment variables:
|
