Researchers introduce a fast-slow architecture for autonomous driving that separates a frozen 7B vision-language model (operating at 5 Hz) from a lightweight action expert (operating at 20 Hz). The slow model provides a cached scene representation, while the fast expert uses this cache and the current camera frame to generate waypoints at every simulation tick. In CARLA simulations on LangAuto-Short routes, this approach achieves 94% route completion compared to 37% for a frame-skipping baseline, and per-tick freshness reduces red-light violations by a third. The system also demonstrates strong zero-shot transfer to unseen towns and significantly lowers waypoint error compared to the backbone model's own action head.

A new preprint addresses the paradox that score-based generative models can cover all modes of a multimodal distribution but may not learn the correct relative mode amplitudes (mixture weights). The authors show that generated samples can still recover mixture weights accurately if the score functions at intermediate noise levels are informative. They introduce the diffusion score sensitivity index (DSSI), which quantifies how changes in parameters affect the diffusion score matching loss and governs estimation accuracy. Empirical results demonstrate that DSSI predicts mixture weight recovery and that noise schedule choices can impact sensitivity and mode amplification.
