Briefings

CARE is a method for selecting certified accelerators for vision-language-action models, ensuring acceleration-induced failure risk stays below a user-specified budget. It uses paired rollouts on a calibration set to guarantee that at least 85.8% of reference-solved episodes are preserved while maintaining speedups of 9.0 to 10.8 times. The approach deploys the fastest certified candidate or falls back to the reference if none qualify, applying unchanged across diverse acceleration mechanisms.

Key points

• CARE introduces a certified accelerator selection method using paired rollouts on a calibration set to guarantee acceleration-induced failure risk stays below a user-specified budget.
• On four LIBERO suites with OpenVLA-OFT, CARE certifies 9.0--10.8times speedups while guaranteeing (at 95% confidence) that at least 85.8% of reference-solved episodes are preserved.

Context

Vision-language-action models have advanced rapidly, but running them at every control step remains expensive. Prior work accelerates inference using techniques like action chunking and visual-token pruning, but acceleration may discard information and break tasks the original policy would solve. Measuring these failures is challenging because action deviations compound over closed-loop trajectories, meaning task failure is only observable across full episodes. CARE addresses this by relying only on terminal outcomes and measured compute.

Limitations

The evidence is limited to four LIBERO suites with OpenVLA-OFT. The study uses paired rollouts on a calibration set for certification, which may not generalize to all acceleration mechanisms or diverse environments. The 95% confidence interval applies only to the calibration set, and the study does not report results for all tested agents or regions.
