{\Omega}-QVLA: Robust Quantization for Vision-Language-Action Models via Composite Rotation and Per-step Scaling
arXiv:2605.28803v1 Announce Type: cross Abstract: Vision-Language-Action (VLA) models unify perception, reasoning, and control within a single policy, yet their multi-billion-parameter backbones and diffusion-based action heads make on-device deployment prohibitively expensive. Prior quantization efforts offer only partial solutions, compressing the LLM backbone while leaving the DiT action head at full precision, or resorting to mixed-precision schemes, driven by the belief that uniformly quantizing the action head is inherently unstable. We challenge this assumption with Omega-QVLA, the firs
The increasing complexity and scale of Vision-Language-Action (VLA) models are pushing the limits of current hardware, creating an urgent need for efficient on-device deployment solutions.
This development addresses a critical bottleneck for deploying advanced AI models in real-world, resource-constrained environments, making sophisticated AI more accessible and practical.
The ability to robustly quantize entire VLA models, including action heads, changes prior assumptions about the instability of such uniform compression, opening new avenues for efficiency.

AI models with perception, reasoning, and control capabilities become viable for deployment on devices with limited computational power.
This enables broader adoption of sophisticated robotic and autonomous systems in diverse fields, from logistics to personal assistance.
The proliferation of contextually aware and capable AI on edge devices could accelerate the development of more autonomous and intelligent environments.
