Core Viewpoint - The article discusses the technological competition between two architectures for autonomous driving: WEWA (World Engine + World Action Model) represented by Huawei and VLA (Vision-Language-Action) pursued by companies like Li Auto and Xpeng. It highlights the debate on whether large language models (LLMs) are essential for autonomous driving, emphasizing the trade-offs between efficiency and cognitive depth in technology choices [2][4]. Summary by Sections 1. Technological Divergence: WEWA vs. VLA - The year 2025 is identified as a critical turning point for autonomous driving technology, with WEWA and VLA architectures representing opposing approaches. WEWA aims for efficient implementation through "de-linguistic" methods, while VLA focuses on cognitive intelligence via language models [2][4]. 2. Fundamental Differences Between WEWA and VLA - The two architectures differ fundamentally in their information processing logic, core components, and technical goals, particularly regarding the role of language as an intermediary. WEWA emphasizes direct mapping from visual data to actions, while VLA incorporates a three-tiered process involving visual features, language semantics, and control instructions [5][6]. 3. Cost of Language Models - VLA's reliance on large language models incurs significant computational costs, presenting a core bottleneck for mass production. The hardware costs escalate dramatically due to the need for high-performance GPU clusters during training and advanced chips for real-time inference [7][8][9]. 4. Advantages of Language Models - Despite high computational costs, VLA's rise is attributed to the abstracting capabilities and cognitive intelligence provided by language models. These models can compress numerous similar scenarios into concise language, enhancing decision-making in complex situations [10][12][13][14]. 5. Core Trade-offs: Efficiency vs. Intelligence - The necessity of language models in autonomous driving is debated, with no definitive conclusion. In short-term production scenarios (L2-L3), WEWA's efficiency and low latency are more valuable, while in long-term high-level scenarios (L4-L5), VLA's cognitive advantages become essential. The future may see a hybrid approach combining both architectures to balance efficiency and intelligence [15][16][17][18].

最新一篇长达76页的Agentic AI综述
自动驾驶之心· 2025-10-28 00:03
Core Insights - The article discusses the evolution of Agentic AI from pipeline-based systems to model-native paradigms, emphasizing the internalization of reasoning, memory, and action capabilities within the models themselves [1][44]. - It highlights the role of reinforcement learning (RL) as a driving force in transforming static models into adaptive, goal-oriented entities capable of learning from interactions with their environment [1][44]. Background - The rapid advancement of generative AI has primarily focused on reactive outputs, lacking long-term reasoning and environmental interaction. The shift towards Agentic AI emphasizes three core capabilities: planning, tool usage, and memory [3]. - Early systems relied on pipeline paradigms where these capabilities were externally orchestrated, leading to passive models that struggled in unexpected scenarios. The new model-native paradigm integrates these capabilities directly into the model parameters, allowing for proactive decision-making [3][6]. Reinforcement Learning for LLMs - The scarcity of programmatic data and vulnerability to out-of-distribution scenarios necessitate the use of result-driven RL to internalize planning and other capabilities, moving away from prompt-induced behaviors [6][7]. - RL offers advantages over supervised fine-tuning (SFT) by enabling dynamic exploration and relative value learning, transforming models from passive imitators to active explorers [8][9]. Unified Paradigm and Algorithm Evolution - Early RLHF methods excelled in single-turn alignment but struggled with long-term, multi-turn, and sparse rewards. Newer result-driven RL methods like GRPO and DAPO enhance training stability and efficiency [12]. - The evolution of algorithms involves leveraging foundational models to provide priors while refining capabilities through interaction and rewards in task environments [12]. Core Capabilities: Planning - The pipeline paradigm views planning as automated reasoning and action sequence search, which is limited in flexibility and stability under complex tasks [14][15]. - The model-native paradigm integrates planning capabilities directly into model parameters, enhancing flexibility and robustness in open environments [15][18]. Core Capabilities: Tool Usage - Early systems embedded models in fixed nodes, lacking flexibility. The model-native transition internalizes decision-making regarding tool usage, forming a multi-objective decision problem [21][22]. - Challenges remain in credit assignment and environmental noise, which can destabilize training. Modular training approaches aim to isolate execution noise and improve sample efficiency [22]. Core Capabilities: Memory - Memory capabilities have evolved from external modules to integral components of task execution, emphasizing action-oriented evidence governance [27][30]. - Short-term memory utilizes techniques like sliding windows and retrieval-augmented generation (RAG), while long-term memory focuses on external libraries and parameter-based internalization [30]. Future Directions - The trajectory of Agentic AI indicates a shift towards deeper integration between models and their environments, moving from systems designed to use intelligence to those that grow intelligence through experience and collaboration [44].
