瘦身90%還能飛？ControlNeXt讓鋼鐵俠跳美女舞蹈 動作精準到手指
賈佳亞團隊開發的ControlNeXt是一個開源的圖像/視頻生成引導工具，旨在簡化AI模型的使用過程。該工具體積小巧，與Stable Diffusion家族的模型如SDXL、SD1.5兼容，支持多種控制模式，如邊緣引導、姿勢控制、遮罩和景深控制。其“減肥祕訣”在於採用了更高效的結構，將“大胃王”控制分支替換爲由少量ResNet塊組成的“輕食套餐”，使模型體積減少到原來的十分之一，同時保持強大的控制能力。ControlNeXt在生成速度上表現出色，僅增加10.4%的延時，遠低於ControlNet的41.9%。此外，它通過交叉歸一化技術優化特徵分佈，提高模型的適應性和控制效果。此工具不僅提升了AI藝術創作的靈活性和效率，還能創造出風格多樣的跨次元角色，爲AI藝術領域帶來新的突破。
