RL Token: Bootstrapping Online RL with Vision-Language-Action Models

Charles Xu, Jost Tobias Springenberg, Michael Equi +4

Vision-language-action (VLA) models can learn to perform diverse manipulation skills "out of the box," but achieving the precision and speed that real-world tasks demand requires f…

$π_{0.7}$ : a Steerable Generalist Robotic Foundation Model with Emergent Capabilities

Physical Intelligence, Bo Ai, Ali Amin +85

We present a new robotic foundation model, called $π_{0.7}$ , that can enable strong out-of-the-box performance in a wide range of scenarios. $π_{0.7}$ can follow diverse language i…
