New ComfyUI Node Enables Negative Prompts for Krea 2 Turbo at CFG 1
1wndrla17 · reddit · 2026-08-11
Since the distilled Krea 2 Turbo is designed to run at CFG 1, standard CFG-based negative prompting fails or adds compute overhead. A developer released an open-source ComfyUI custom node using Normalized Attention Guidance (NAG) to suppress concepts without altering the sampler CFG.
The node supports Krea 2 Turbo and Krea2Edit (including reference latents). Benchmarks indicate a 30% slowdown on the first run or after changing prompts, dropping to about 10% overhead when prompt encodings are cached.
