What can Astra do when given a humanoid embodiment?

We built HomeBody to find out. Controlled by GPT Astra, it carries out long-horizon tasks in a previously unseen kitchen—from tidying up across the room to retrieving remembered objects from ambiguous requests—without environment-specific training data or additional policy learning.

Here's how we did it [eyes emoji]: tml.stanford.edu/homebody/

Tweet by Gio Huh announcing HomeBody, a humanoid robot controlled by GPT Astra performing long-horizon kitchen tasks in an unseen environment without environment-specific training. Embedded video frame shows a humanoid robot in a kitchen with a 'Stage 3 of 3: Deploy it' label.

Astra does seem like a step change in spatial reasoning. Impressive....

Tweet praising 'Astra' as a step change in spatial reasoning, with an embedded line chart: GPT Astra stays roughly 78-97% accuracy across the x-axis range, near the human-best line and well above human average at higher x values, while all other models fall from about 45-67% at x=2 toward the random baseline (~10%) by x=14.
