# pixart-900m-1024-ft

This is a full rank finetune derived from [terminusresearch/pixart-900m-1024](https://huggingface.co/terminusresearch/pixart-900m-1024).



The main validation prompt used during training was:

```
a cute anime character named toast holding a sign that says SOON, sitting next to a red square on her left side, and a transparent sphere on her right side
```

## Validation settings
- CFG: `6.5`
- CFG Rescale: `0.7`
- Steps: `30`
- Sampler: `euler`
- Seed: `42`
- Resolutions: `1024x1024,1152x960,896x1152`

Note: The validation settings are not necessarily the same as the [training settings](#training-settings).

The text encoder **was not** trained.
You may reuse the base model text encoder for inference.

## Inference


```python
import torch
from diffusers import DiffusionPipeline



model_id = "pixart-900m-1024-ft"
prompt = "a cute anime character named toast holding a sign that says SOON, sitting next to a red square on her left side, and a transparent sphere on her right side"
negative_prompt = "malformed, disgusting, overexposed, washed-out"

pipeline = DiffusionPipeline.from_pretrained(model_id)
pipeline.to('cuda' if torch.cuda.is_available() else 'mps' if torch.backends.mps.is_available() else 'cpu')
image = pipeline(
    prompt=prompt,
    negative_prompt='',
    num_inference_steps=30,
    generator=torch.Generator(device='cuda' if torch.cuda.is_available() else 'mps' if torch.backends.mps.is_available() else 'cpu').manual_seed(1641421826),
