τ0-VLA: Hierarchical Robot Foundation Model with World-Model-Guided Test-Time Search
sii-research · hf · 2026-08-22
τ0-VLA is a hierarchical vision-language-action (VLA) robot foundation model. Its key idea is applying world-model-guided test-time computation to high-level subtask decisions.
- The architecture is hierarchical: a high level plans subtasks for long-horizon goals, while a low level executes concrete manipulation actions.
- The high level scales its computation via world-model-guided test-time search, improving reliability and success on long-horizon robot manipulation.
