  This model is open access and available to all, with a CreativeML OpenRAIL-M license further specifying rights and usage.
  The CreativeML OpenRAIL License specifies:

  1. You can't use the model to deliberately produce nor share illegal or harmful outputs or content
  2. CompVis claims no rights on the outputs you generate, you are free to use them and are accountable for their use which must not go against the provisions set in the license
  3. You may re-distribute the weights and use the model commercially and/or as a service. If you do, please be aware you have to include the same use restrictions as the ones in the license and share a copy of the CreativeML OpenRAIL-M to all your users (please read the license entirely and carefully)

This repository hosts weights for a Rust based version of Stable Diffusion.
These weights have been directly adapted from the
[stabilityai/stable-diffusion-2-1](https://huggingface.co/stabilityai/stable-diffusion-2-1)
weights, they can be used with the
[diffusers-rs](https://github.com/LaurentMazare/diffusers-rs) crate.

To do so, checkout the diffusers-rs repo, copy the weights in the `data/`
directory and run the following command:

```bash
cargo run --example stable-diffusion --features clap -- --prompt "A rusty robot holding a fire torch."
```

This is for the image-to-text pipeline, example using the image-to-image and
inpainting pipelines can be found in the
[crate readme](https://github.com/LaurentMazare/diffusers-rs/blob/main/README.md).

## Model Details
- **Developed by:** Robin Rombach, Patrick Esser
- **Model type:** Diffusion-based text-to-image generation model
- **Language(s):** English
- **License:** [CreativeML Open RAIL++-M License](https://huggingface.co/stabilityai/stable-diffusion-2/blob/main/LICENSE-MODEL)
- **Model Description:** This is a model that can be used to generate and modify images based on text prompts. It is a Latent Diffusion Model that uses a fixed, pretrained text encoder (OpenCLIP-ViT/H).

## Weight Extraction

The weights have been converted by downloading them from the stabilityai/stable-diffusion-2-1 repo,
and then running the following commands in the
[diffusers-rs repo](https://github.com/LaurentMazare/diffusers-rs).

After downloading the files, use Python to convert them to `npz` files.

```python
import numpy as np
import torch
model = torch.load("./vae.bin")
np.savez("./vae_v2.1.npz", **{k: v.numpy() for k, v in model.items()})
model = torch.load("./unet.bin")
np.savez("./unet_v2.1.npz", **{k: v.numpy() for k, v in model.items()})
```

Convert these `.npz` files to `.ot` files via `tensor-tools`.

```bash
cargo run --release --example tensor-tools cp ./data/vae_v2.1.npz ./data/vae_v2.1.ot
cargo run --release --example tensor-tools cp ./data/unet_v2.1.npz ./data/unet_v2.1.ot
```
