This README has been auto-generated by the HF Job run linked below and the whole repository is a reproducible artifact of this Job
Ahead-of-time repository
AoT repos contain pre-compiled binaries of PyTorch models, enabling:
- fast startup times (no
torch.compileneeded) - significant speedup
- ZeroGPU compatibility
How to use
import spaces
import torch
from diffusers.models import Flux2Transformer2DModel
from diffusers.pipelines.flux2.pipeline_flux2 import Flux2Pipeline
from transformers import BitsAndBytesConfig
from transformers import Mistral3ForConditionalGeneration
repo_id = "black-forest-labs/FLUX.2-dev"
text_encoder = Mistral3ForConditionalGeneration.from_pretrained(
repo_id,
subfolder='text_encoder',
device_map='auto',
quantization_config=BitsAndBytesConfig(load_in_8bit=True),
)
transformer = Flux2Transformer2DModel.from_pretrained(
repo_id,
subfolder="transformer",
torch_dtype=torch.bfloat16
)
pipeline = Flux2Pipeline.from_pretrained(
repo_id,
text_encoder=text_encoder,
transformer=transformer,
torch_dtype=torch.bfloat16
).to('cuda')
spaces.aoti_load(
module=pipeline.transformer,
repo_id='cbensimon/Flux2Transformer2DModel-sm120-cu130-r75',
)
How to reproduce or customize
# Install hf CLI
