What stands out
What its maker marketed at launch, and what people found later, each with its source.
Open generalist policy on Open X-Embodiment
Transformer diffusion policy (27M Small / 93M Base) trained on 800k trajectories from Open X-Embodiment; instructed by language or goal images; evaluated on 9 robot platforms; fine-tunes to new sensors and action spaces in hours on consumer GPUs.
Notes
Early (2024) fully open generalist robot policy; now mostly a baseline. Parameter sizes from the project page.
