The development of multimodal large language models (MLLMs) has led to growing interest in LLM-based autonomous driving, leveraging their powerful inference capabilities. Leveraging the powerful reasoning capabilities of MLLMs to improve planning behavior is challenging because they require full 3D situation awareness beyond 2D reasoning. To address this challenge, this work proposes OmniDrive, a comprehensive framework for robust alignment between agent models and 3D driving tasks. The framework starts with a novel 3D MLLM architecture that uses sparse queries to lift and compress observation representations into 3D, which are then fed into the LLM. This query-based representation allows us to jointly encode dynamic objects and static map elements (e.g., traffic roads), providing a concise world model for perception-action alignment in 3D. We further propose a new benchmark that includes comprehensive visual question answering (VQA) tasks including scene description, traffic rules, 3D grounding, counterfactual reasoning, decision making, and planning. Extensive research demonstrates OmniDrive's superior reasoning and planning capabilities in complex 3D scenes.

"I think AI tools are changing the learning opportunities for college students. We believe in developing students in core courses, but more and more people also want to get a perspective of computational and statistical thinking," said University of Chicago President Paul Alivisatos in an interview with Deloitte Nitin Mittal at the Davos Forum in January. He believes that people will have to become creators and co-creators of AI, which means that learning and other aspects need to adapt to some major changes. Digital intelligence and critical thinking Professor Alexa Joubin of George Washington University described artificial intelligence as a “heuristic tool” in the humanities and explores how it changes
