# pixart-900m-1024-ft
This is a full rank finetune derived from [ptx0/pixart-900m-1024-ft-large](https://huggingface.co/ptx0/pixart-900m-1024-ft-large).
The main validation prompt used during training was:
```
ethnographic photography of teddy bear at a picnic, ears tucked behind a cozy hoodie looking darkly off to the stormy picnic skies
```
## Validation settings
- CFG: `4.5`
- CFG Rescale: `0.0`
- Steps: `25`
- Sampler: `None`
- Seed: `42`
- Resolutions: `1024x1024,1344x768,916x1152`
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 = 'ethnographic photography of teddy bear at a picnic, ears tucked behind a cozy hoodie looking darkly off to the stormy picnic skies'
negative_prompt = 'blurry, cropped, ugly'
pipeline = DiffusionPipeline.from_pretrained(model_id)
pipeline.to('cuda' if torch.cuda.is_available() else 'mps' if torch.backends.mps.is_available() else 'cpu')
prompt = "ethnographic photography of teddy bear at a picnic, ears tucked behind a cozy hoodie looking darkly off to the stormy picnic skies"
