Asynchronous Robot Inference: Decoupling Action Prediction and Execution
What changed
Asynchronous Robot Inference: Decoupling Action Prediction and Execution - Getting started - Async inference: a deep dive - 1. Sequential inference keeps acting out the current action chunk even after failure to grasp the object, while async inference can replan and act the new action chunk. We introduced asynchronous inference in SmolVLA, and found it to result in a ~2x speed-up in task completion time with comparable task success rate.
Why it matters
A concrete addition to Practical AI: Tools, Models & Frameworks: it changes what's available to builders today rather than being general commentary.
