Seemingly impressive VLA performance on robotic benchmarks crumbles when stress-tested with causal interventions, exposing a reliance on brittle shortcuts rather than genuine embodied reasoning.

Stop guessing how long LLM outputs will be – modeling the *distribution* of possible lengths slashes latency by 2x and boosts throughput by 40%.

Diffusion models can now generate high-fidelity virtual contrast-enhanced CT scans from non-contrast scans, potentially reducing the need for invasive contrast agents and radiation exposure.
