arXiv:2606.15631v1 Announce Type: cross Abstract: Extending a vision-language-action (VLA) policy to a new task typically requires task-specific teleoperated demonstrations and per-task fine-tuning, making adaptation costly in both data collection and compute. In this paper, we show that this target-side per-task adaptation cost can be replaced by retrieval. Our retrieval-augmented policy is trained once on paired demonstrations from the target embodiment (query) and a cheaper embodiment (pool, e.g., human-hand video), then frozen. New tasks are added at deployment by appending pool-side demon
This development addresses a critical bottleneck in extending AI models to new tasks, specifically in vision-language-action models, by developing a more efficient adaptation mechanism.
This research reduces the cost and complexity of deploying AI for new robotic or agentic tasks, accelerating broader adoption and capability expansion in physical and digital domains.
The paradigm shifts from costly per-task fine-tuning to a more efficient retrieval-based adaptation, making AI application more agile and scalable without extensive retraining.
