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.
|
26 |
+
|
27 |
+
![image/png](https://huggingface.co/shuttleai/shuttle-3.1-aesthetic/resolve/main/demo.png)
|
28 |
+
|
29 |
+
You can try out the model through a website at https://chat.shuttleai.com/images
|
30 |
+
|
31 |
+
## Using the model via API
|
32 |
+
You can use Shuttle 3.1 Aesthetic via API through ShuttleAI
|
33 |
+
- [ShuttleAI](https://shuttleai.com/)
|
34 |
+
- [ShuttleAI Docs](https://docs.shuttleai.com/)
|
35 |
+
|
36 |
+
## Using the model with 🧨 Diffusers
|
37 |
+
Install or upgrade diffusers
|
38 |
+
```shell
|
39 |
+
pip install -U diffusers
|
40 |
+
```
|
41 |
+
Then you can use `DiffusionPipeline` to run the model
|
42 |
+
```python
|
43 |
+
import torch
|
44 |
+
from diffusers import DiffusionPipeline
|
45 |
+
|
46 |
+
# Load the diffusion pipeline from a pretrained model, using bfloat16 for tensor types.
|
47 |
+
pipe = DiffusionPipeline.from_pretrained(
|
48 |
+
"shuttleai/shuttle-3.1-aesthetic", torch_dtype=torch.bfloat16
|
49 |
+
).to("cuda")
|
50 |
+
|
51 |
+
# Uncomment the following line to save VRAM by offloading the model to CPU if needed.
|
52 |
+
# pipe.enable_model_cpu_offload()
|
53 |
+
|
54 |
+
# Uncomment the lines below to enable torch.compile for potential performance boosts on compatible GPUs.
|
55 |
+
# Note that this can increase loading times considerably.
|
56 |
+
# pipe.transformer.to(memory_format=torch.channels_last)
|
57 |
+
# pipe.transformer = torch.compile(
|
58 |
+
# pipe.transformer, mode="max-autotune", fullgraph=True
|
59 |
+
# )
|
60 |
+
|
61 |
+
# Set your prompt for image generation.
|
62 |
+
prompt = "A cat holding a sign that says hello world"
|
63 |
+
|
64 |
+
# Generate the image using the diffusion pipeline.
|
65 |
+
image = pipe(
|
66 |
+
prompt,
|
67 |
+
height=1024,
|
68 |
+
width=1024,
|
69 |
+
guidance_scale=3.5,
|
70 |
+
num_inference_steps=4,
|
71 |
+
max_sequence_length=256,
|
72 |
+
# Uncomment the line below to use a manual seed for reproducible results.
|
73 |
+
# generator=torch.Generator("cpu").manual_seed(0)
|
74 |
+
).images[0]
|
75 |
+
|
76 |
+
# Save the generated image.
|
77 |
+
image.save("shuttle.png")
|
78 |
+
```
|

+
|
81 |
+
## Using the model with ComfyUI
|
82 |
+
|
83 |
+
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).
|
84 |
+
|
85 |
+
## Training Details
|
86 |
+
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.
