NVIDIA’s VFlash speeds robot trajectory decoding 12x, cuts prediction errors by 61%
NVIDIA researchers have developed a new visual planning method called VFlash that accelerates robot trajectory decoding by up to 12 times while reducing 3D trajectory prediction errors by as much as 61% in specific tests. The method allows vision-language models to generate complete trajectories in a single pass, cutting inference latency by about 80% on NVIDIA's Jetson Thor and DGX Spark platforms. In robot manipulation tests, VFlash reduced average displacement error significantly compared with conventional autoregressive approaches. The research was published in November 2026.

nipulation tests, VFlash also cut overall inference latency by about 80% on NVIDIA’s Jetson Thor and DGX Spark platforms, potentially helping robots respond faster to changing environments. The research addresses a limitation in conventional VLMs, which often generate spatial predictions one coordinate at a time. As robots need to predict longer trajectories, track more objects and process increasingly detailed spati
