What happened

Jim Fan introduces VFlash, which outputs fixed-length geometric predictions such as object locations and robot trajectories in parallel rather than one token at a time. He reports up to 12x faster action decoding, a 5.1x overall robot inference speedup on edge GPUs including Jetson Thor and DGX Spark, and up to 61% lower 3D trajectory error than the VLM backbone. Fan says the paper and source code are open.

The era of System One Vision Model is here! Introducing VFlash: parsing the visual world in parallel at unmatched speeds for Physical AI.

Most embodied prediction tasks like object localization, robot trajectory planning, and dense 3D motion are fixed-length float vectors. For example, a bounding box is always 6 tokens, a 10-waypoint robot arm trajectory is 54: we know these beforehand. Instead of decoding one token at a time, we can output the entire geometric shape in one go.

VFlash enables up to 12x faster action decoding and a 5.1x overall robot inference speedup on edge GPUs like the Jetson Thor and DGX Spark. What’s surprising is that it ends up even more accurate than the VLM backbone, with up to 61% lower 3D trajectory error. The intuition is that VFlash avoids the cascading errors of autoregressive decoding, where every coordinate is written in ink and every later point loses the chance to backspace.

Everything that moves will be autonomous, and everything autonomous will need to think on its own chip. The next inference revolution is physical reasoning at the speed of reflex.

And as always, it’s open paper, open source! Link in thread:

The story so far

Jim Fan introduced VFlash, a model that predicts fixed-length geometric outputs such as object locations and robot trajectories in parallel, and said its paper and source code are open. He reports up to 12× faster action decoding and a 5.1× overall robot inference speedup on edge GPUs, including Jetson Thor and DGX Spark. Fan also reports up to 61% lower 3D trajectory error than the vision-language model backbone. These are reported results for VFlash; the figures describe different measures of speed and accuracy.
