A new open-source custom node for ComfyUI has been developed to enable negative prompting for Krea 2 Turbo and Krea2Edit models, even when the sampler CFG is set to 1. This node utilizes Normalized Attention Guidance (NAG) to suppress unwanted concepts without increasing the CFG, which can negatively impact distilled Turbo models. The implementation adds a slight performance overhead, approximately 10-30% depending on prompt caching, and is available on GitHub. AI
IMPACT Provides enhanced control over image generation for users of Krea 2 Turbo and Krea2Edit models within the ComfyUI ecosystem.
RANK_REASON Release of a custom node for an existing platform, not a core model release.
