arXiv:2602.18532v2 Announce Type: replace-cross Abstract: Following the rise of large foundation models, Vision-Language-Action models (VLAs) emerged, leveraging strong visual and language understanding from Vision-Language Models for general-purpose policy learning. Yet, the current VLA landscape remains fragmented and exploratory. Although many groups have proposed their own VLA models, inconsistencies in training protocols and evaluation settings make it difficult to identify which design choices truly matter. To bring structure to this evolving space, we reexamine the VLA design space unde
The proliferation of various Vision-Language-Action (VLA) models has created fragmentation, necessitating a systematic approach to identify effective design choices.
This research provides crucial recipes for building robust VLA models, which are foundational for advancing general-purpose policy learning in AI, directly impacting industries like robotics.
The understanding of effective VLA model design and training will become clearer, leading to more consistent performance and faster development cycles in complex AI systems, especially for embodied AI.
