arXiv:2605.24011v2 Announce Type: replace-cross Abstract: Vision-Language-Action (VLA) models exhibit remarkable action generation for embodied intelligence, but their heavy compute make deployment on edge platforms impractical. Aggressive, sub-4-bit weight quantization is the natural solution, yet existing post-training quantization (PTQ) methods suffer severe performance degradation in this regime. To address this, we introduce ActQuant, an action-guided mixed-precision PTQ framework that operates in two stages: (1) an inter-tensor bit allocator that assigns each weight matrix a single bit-w
The increasing complexity and computational demands of advanced AI models like VLAs necessitate innovative solutions for efficient deployment on less powerful hardware, making quantization research critical.
This development allows sophisticated AI models to operate effectively on edge devices, expanding their reach and utility in real-world applications where power and compute constraints are significant.
The ability to perform aggressive, sub-4-bit quantization without severe performance degradation fundamentally alters the economic and practical feasibility of deploying VLAs on edge hardware.
