τ₀-VLA breakdown: Turning subtask decisions into a scalable reasoning problem

The article breaks down τ₀-VLA, a hierarchical robot foundation model open-sourced on July 27, 2026 by Luo Jianlan's team at the Shanghai Innovation Institute (SII). The model targets long-horizon mobile manipulation on the order of ten minutes in home scenarios, such as meal prep, folding and storing clothes, and tidying across rooms. Its core idea is to turn "what should the next subtask be" into a reasoning problem that can be scaled with more compute.
