ProbeFlow: Training-Free Adaptive Flow Matching for Vision-Language-Action Models
ProbeFlow addresses high inference latency in Vision-Language-Action models using Flow Matching by dynamically scheduling integration steps based on trajectory complexity. It introduces a training-free method called the Lookahead Linearity Probe to quantify geometric curvature. This allows the system to skip unnecessary calculations in straight paths, significantly reducing action decoding time and improving real-time control performance without requiring model retraining.
