Flex.1-alpha is a powerful text-to-image generation model based on an 8 billion parameter corrected flow transformer architecture. It inherits features from FLUX.1-schnell and generates images without the need for CFG through trained guided embedders. The model supports fine-tuning and is open-source (Apache 2.0), making it suitable for use in various inference engines like Diffusers and ComfyUI. Its main advantages include efficient generation of high-quality images, flexible fine-tuning capabilities, and strong community support. The development background aims to address the compression and optimization issues of image generation models while continuously improving model performance through ongoing training.
