Model reference · open weights
shuttle-jaguar is an open-weight image model from shuttleai. AxForge deploys and operates it for you on dedicated EU-owned hardware — with the licence handled where one is required.
Available as managed deployment — configured and operated for you on dedicated EU hardware, quoted per deployment.

About
These model variants provide different precision levels and formats optimized for diverse hardware capabilities and use cases
Shuttle Jaguar is a text-to-image AI model designed to generate highly aesthetic, cinematic, and realistic images from textual prompts in just four steps, all while being licensed under Apache 2.
You can use Shuttle Jaguar via API through ShuttleAI
Install or upgrade diffusers
pip install -U diffusers
Then you can use DiffusionPipeline to run the model
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-jaguar", 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 it via the API
Once AxForge deploys shuttle-jaguar for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (shuttle-jaguar below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/images/generations \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"shuttle-jaguar","prompt":"a red bicycle","size":"1024x1024"}'
