Training and Evaluating Diffusion Policies with Long Context Lengths

arXiv:2606.16447v1 Announce Type: cross Abstract: Imitation learning has enabled highly-dexterous robotic manipulation from RGB observations. Policies trained with these methods, however, typically condition robot actions on only a short history of observations. These policies cannot solve tasks that require memory and can get stuck repeatedly executing the same failing motions. In this work, we first benchmark policy performance as context length is incrementally increased from short to long, across a spectrum of tasks with varying local stability and memory requirements, and in multiple data

Why this matters
Why now

The continuous improvement in AI models, especially large language models (LLMs) and diffusion transformers, is enabling longer context windows which is now being applied to robotics.

Why it’s important

Improved long-context capabilities in robotic policies address fundamental limitations in sequential decision-making, moving robotics closer to general-purpose applications requiring complex memory and planning.

What changes

Robots will be able to perform tasks requiring longer operational memory and adaptive responses to changing environments, overcoming previous challenges of short-sighted, repetitive failures.
