Abstract: Recent years have witnessed remarkable progress in autonomous driving, yet generalization to long-tail and open-world scenarios remains the primary bottleneck for large-scale deployment. To address this, one line of research explores LLMs and VLMs for their vision-language understanding and reasoning capabilities, equipping AVs with the ability not only to interpret rare and safety-critical situations when generating driving actions. In parallel, another line investigates generative world models to capture the spatio-temporal evolution of driving scenes, enabling agents to imagine and evaluate possible futures before acting. Inspired by human intelligence, which seamlessly unites understanding and imagination as a hallmark of AGI, this work explores a unified model that brings these two capabilities together for autonomous driving.
We present LMGenDrive, the first framework that unifies LLM-based multimodal reasoning with generative world models for end-to-end closed-loop autonomous driving. Given multi-view camera inputs and natural-language instructions, our model generates both realistic future driving videos and corresponding control signals. By coupling an LLM with generative video capabilities, LMGenDrive gains complementary benefits: future video prediction enhances the LLM's spatio-temporal scene understanding, while the LLM itself provides reasoning and instruction-following capabilities. A progressive three-stage training strategy—ranging from vision pretraining to multi-step long-horizon driving—is proposed to further improve stability and performance.
The resulting model can also operate in two complementary modes: low-latency online planning and autoregressive offline video generation.
Experiments show that LMGenDrive significantly outperforms state-of-the-art methods on challenging closed-loop driving benchmarks, improving instruction following, spatio-temporal reasoning, and robustness to rare scenarios. 
Our work not only sets a new state-of-the-art in autonomous driving, but also demonstrates that unifying multimodal understanding and generation offers a foundational new paradigm toward achieving embodied AGI.
