# Testing environment for the Freedom Model
Finetuned model of SD 2.1 768X produced by [@artificialguybr](https://twitter.com/artificialguybr).

## Resources
- The weights were released [here](LINK_TO_WEIGHTS).
- You can find example prompts [here](LINK_TO_EXAMPLE_PROMPTS).

## Demonstration
This demonstration is running on the [makeai.run API](LINK_TO_MAKEAI.RUN_API).

## Acknowledgements
