FLUX.2-klein-4B-sm90-cu128-torch29-rad

[!NOTE] 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.compile needed)
• significant speedup
• ZeroGPU compatibility

How to use

import spaces
import torch
from diffusers.pipelines.flux2.pipeline_flux2_klein import Flux2KleinPipeline

pipeline = Flux2KleinPipeline.from_pretrained(
    'black-forest-labs/FLUX.2-klein-4B',
    torch_dtype=torch.bfloat16
).to('cuda')

spaces.aoti_load(
    module=pipeline.transformer,
    repo_id='cbensimon/FLUX.2-klein-4B-sm90-cu128-torch29-rad',
)

How to reproduce or customize

# Install hf CLI
curl -LsSf https://hf.co/cli/install.sh | bash

# Login
hf auth login

# Get the job file and edit (user section) if needed
hf download cbensimon/FLUX.2-klein-4B-sm90-cu128-torch29-rad job.py

# Run the job and change flavor or image if needed
hf jobs uv run job.py \
    --flavor h200 \
    --image pytorch/pytorch:2.9.1-cuda12.8-cudnn9-devel \
    --secrets HF_TOKEN

The following job environment variables can be used to customize the repo name generation:

• OUTPUT_REPO_NAMESPACE: taken from HF_TOKEN otherwise
• OUTPUT_REPO_BASE_NAME: defaults to module class name
• OUTPUT_REPO_ID: fully overtakes name generation

Samples

Generated as part of the compilation job: before and after compilation

Speedup: 1.65x (note that this might not always reflect actual performance gain)
