FLUX.1-dev-Controlnet-Union-alpha is a text-to-image generation model belonging to the Diffusers series, utilizing ControlNet technology for control. Currently, it is in the alpha stage and has not yet been fully trained, but it has demonstrated the effectiveness of its code. This model aims to promote the growth of the Flux ecosystem through the rapid expansion of the open-source community. Although the fully trained Union model may not outperform specialized models in certain areas such as pose control, its performance is expected to improve as training progresses.
