Jim Fan declares VLA dead: multimodal coding is the right action space for robotics' System 2
DrJimFan · x · 2026-09-09
NVIDIA's Jim Fan tweeted that Astra represents the new VLA (Vision-Language-Action) paradigm, declaring "VLA is dead. Long live VLA 2.0."
His core argument: multimodal coding is the right action space for the System 2 (slow) brain of robotics — high-level reasoning and planning should be expressed as generated code rather than raw continuous action tokens. The take signals a possible shift in embodied AI from end-to-end VLA toward hybrid designs using code as an intermediate representation.
