阿里新一代的大模型 Qwen 3 今早发布,新旗舰 Qwen3-235B-A22B 的评测成绩,和 DeepSeek R1、Grok-3、Gemini-2.5-Pro 不相上下。这一代全系列模 型都支持混合推理,对 Agent 的支持也上了新台阶。 随着 Qwen 2.5 和 3 的发布,全球的开源模型生态也呈现了一种新形态:以 DeepSeek+Qwen 的中国开源组合,取代了过去 Llama 为主,Mistral 为辅的开 源生态。Qwen 系列的衍生模型目前已经是 HuggingFace 上最受欢迎的开源模型,衍生模型的数量也超过了 Llama 系列。而 DeepSeek 对于开源模型生态 的冲击和贡献,也有目共睹。 与大模型六小龙相比,主打开源的 Qwen 和 DeepSeek 无疑在国际市场赢得了更多开发者和创业者的关注,来自开源社区的代码贡献、更多优秀微调版本 的出现,也在以另外一种方式推动模型能力的进步。 可以说, 开源,正在成为中国大模型公司进入全球市场的最佳路径。 而对阿里云来说,Qwen+阿里云的配合,「模型-云-行业应用」的打法,走出了国内 MaaS 模式的新方向,也在很大程度上降低了国 ...

Core Viewpoint - The article discusses the current state of AI agents, indicating that most are still in the "pilot purgatory" phase and have not yet transitioned to real-world applications, despite expectations for 2025 to be the "year of AI agents" [1][2]. Group 1: Current State of AI Agents - A survey on social platform X reveals that 64.2% of AI agents are stuck in pilot purgatory, while only 6.4% are smarter than the hype [2]. - The article highlights the need for advancements in AI systems to enhance their stability and reliability in enterprise applications [2]. Group 2: Introduction of RAGEN - A new system called RAGEN, developed by a team including researchers from Northwestern University, Microsoft, Stanford University, and the University of Washington, aims to improve AI agents' performance in real-world scenarios [2][5]. - RAGEN focuses on multi-turn interaction scenarios, requiring agents to reason under uncertainty and remember historical dialogues [5]. Group 3: StarPO Framework - RAGEN is built on a custom reinforcement learning framework named StarPO, which emphasizes learning through experience rather than rote memorization [5][7]. - The StarPO framework consists of two alternating phases: rollout, where the LLM generates complete interaction sequences, and update, where the model updates parameters based on normalized cumulative rewards [7]. Group 4: Training Challenges and Solutions - The article discusses the "Echo Trap" phenomenon, where agents generate repetitive responses due to early high rewards, leading to a decline in reasoning ability [12]. - To address training stability, the enhanced version StarPO-S introduces three key mechanisms: uncertainty-based rollout filtering, removal of KL penalty, and asymmetric PPO clipping [19]. Group 5: Evaluation Environments - RAGEN includes three symbolic testing environments to evaluate decision-making capabilities: Bandit, Sokoban, and Frozen Lake, each designed to assess different aspects of agent performance [15][17]. - These environments aim to minimize prior knowledge interference, allowing agents to rely solely on learned strategies for decision-making [15]. Group 6: Future Implications - RAGEN represents a significant step towards developing AI agents with autonomous reasoning capabilities, although challenges remain in applying these methods to real-world business processes [24]. - The article emphasizes the importance of optimizing reward mechanisms to focus on the quality of reasoning processes, not just the correctness of outcomes [24].
