CEED-VLA：实现VLA模型4倍推理加速，革命性一致性蒸馏与早退解码技术！

Core Viewpoint - The article discusses the development of a new model called CEED-VLA, which significantly enhances the inference speed of visual-language-action models while maintaining operational performance, making it suitable for high-frequency dexterous tasks [2][30]. Group 1: Model Development - The CEED-VLA model is designed to accelerate inference through a general method that improves performance across multiple tasks [2]. - The model incorporates a consistency distillation mechanism and mixed-label supervision to enable accurate predictions of high-quality actions from various intermediate states [2][6]. - The Early-exit Decoding strategy is introduced to address inefficiencies in the Jacobi decoding process, achieving up to 4.1× inference speedup and over 4.3× execution frequency [2][15]. Group 2: Experimental Results - Simulations and real-world experiments demonstrate that CEED-VLA significantly improves inference efficiency while maintaining similar task success rates [6][30]. - The model shows a speedup of 2.00× compared to the teacher model and achieves a higher number of fixed tokens, indicating improved performance [19][20]. - In real-world evaluations, CEED-VLA successfully completes dexterous tasks, achieving a success rate exceeding 70% due to enhanced inference speed and control frequency [30][31].
