Shuttle 3.1 Aesthetic is a text-to-image AI model designed to create detailed and aesthetic images from textual prompts in just 4 to 6 steps. It offers enhanced performance in image quality, typography, understanding complex prompts, and resource efficiency.
You can try out the model through a website at https://designer.shuttleai.com/
## Using the model via API
You can use Shuttle 3.1 Aesthetic via API through ShuttleAI

## Using the model with 🧨 Diffusers
Install or upgrade diffusers
```shell
pip install -U diffusers
```
Then you can use DiffusionPipeline to run the model
```python
import torch
from diffusers import DiffusionPipeline
# Load the diffusion pipeline from a pretrained model, using bfloat16 for tensor types.
pipe = DiffusionPipeline.from_pretrained(
"shuttleai/shuttle-3.1-aesthetic", torch_dtype=torch.bfloat16
).to("cuda")
# Uncomment the following line to save VRAM by offloading the model to CPU if needed.
# pipe.enable_model_cpu_offload()
# Uncomment the lines below to enable torch.compile for potential performance boosts on compatible GPUs.
# Note that this can increase loading times considerably.
# pipe.transformer.to(memory_format=torch.channels_last)
# pipe.transformer = torch.compile(
# pipe.transformer, mode="max-autotune", fullgraph=True
# )
# Set your prompt for image generation.
prompt = "A cat holding a sign that says hello world"
# Generate the image using the diffusion pipeline.
image = pipe(
prompt,
height=1024,
width=1024,
guidance_scale=3.5,
num_inference_steps=4,
max_sequence_length=256,
# Uncomment the line below to use a manual seed for reproducible results.
# generator=torch.Generator("cpu").manual_seed(0)
).images[0]
# Save the generated image.
image.save("shuttle.png")
```

## Using the model with ComfyUI
To run local inference with Shuttle 3.1 Aesthetic using [ComfyUI](https://github.com/comfyanonymous/ComfyUI), you can use this [safetensors file](https://huggingface.co/shuttleai/shuttle-3.1-aesthetic/blob/main/shuttle-3.1-aesthetic.safetensors).
## Training Details
Shuttle 3.1 Aesthetic uses Shuttle 3 Diffusion as its base. It can produce images similar to Flux Dev in just 4 steps, and it is licensed under Apache 2. The model was partially de-distilled during training. We overcame the limitations of the Schnell-series models by employing a special training method, resulting in improved details and colors.
