FLUX.3 Image Klein Model Weights Released on Hugging Face
Black Forest Labs has published the model weights for FLUX.3 Image Klein, a new 5.6B parameter open-weights model, on Hugging Face. The model is designed for text-to-image generation and multi-reference image editing. This release provides the open-source and local LLM community with a state-of-the-art model that outperforms several larger open and closed models in internal evaluations. It enables developers and enthusiasts to run advanced image generation and editing tasks locally. FLUX.3 Image Klein requires a prompt and up to 10 reference images to perform text-to-image, single-reference edits, and multi-reference compositions using Qwen3-VL-4B-Instruct. Despite having only 5.6B parameters, it ranks exceptionally well compared to competing models.
## BACKGROUND
Black Forest Labs is an artificial intelligence research lab known for creating the FLUX series of text-to-image models. Open-weights models allow developers to download and run the AI models on their own hardware rather than relying strictly on cloud-based APIs.
