The authors report 95.5% success across 400 LIBERO episodes, with 57-millisecond inference per sixteen-action chunk and 2.4 GiB of GPU memory. In their comparison it was eleven times faster than its teacher, with fewer operations and less memory, while still predicting scene motion. These are manipulation-benchmark results; the paper does not establish the same performance on every edge device or real-world task.",
