About the challenge This hackathon is about experimenting with FLUX.1 Kontext [dev]. Create a LoRA. Combine it with other FLUX models. Build a workflow. Or just try something totally unexpected. You can run Kontext [dev] however you like - locally on your own setup, or through our partners FAL and Ostris' AI Toolkit on Hugging Face if you don’t have GPUs handy. The goal is simple: play, explore, and push Kontext [dev] into new directions. Surprise us with what you make. Get started
FLUX.1 Kontext [dev] is free to download on Hugging Face
