Core Insights - The article discusses the evolution of Visual Tokenizer and its significance in understanding the world, suggesting that the next step in its development is to enhance its ability to comprehend high-level semantics rather than just focusing on pixel-level reconstruction [5][6][9]. Group 1: Visual Tokenizer Research - MiniMax and researchers from Huazhong University of Science and Technology have released a new study on Visual Tokenizer Pre-training (VTP), which has sparked significant interest in the industry [6]. - Traditional visual generation models typically involve a two-step process: compressing images using a tokenizer (like VAE) and then training a generative model in latent space [6]. - The study indicates that improving the performance of generative models can be achieved not only by scaling the main model but also by enhancing the tokenizer [6][8]. - The research reveals that focusing solely on pixel-level reconstruction can lead to a decline in downstream generative quality, as traditional tokenizers tend to favor low-level pixel information over high-level semantic representation [7][8]. - VTP proposes that introducing semantic understanding in tokenizer pre-training can make latent representations more sensitive to high-level semantics without overly memorizing pixel details [8][9]. Group 2: VTP Framework and Findings - The VTP framework integrates image-text contrastive learning (like CLIP), self-supervised learning (like DINOv2), and traditional reconstruction loss to optimize the latent space of visual tokenizers [9][10]. - The framework retains lightweight reconstruction loss for visual fidelity while introducing two semantic-oriented tasks: self-supervised loss based on DINOv2 and contrastive loss based on CLIP [9][10]. - Experimental results show a strong positive correlation between the semantic quality of the latent space (measured by zero-shot classification accuracy) and generative performance (measured by FID) [11]. - The largest VTP model (approximately 700 million parameters) achieved a zero-shot classification accuracy of 78.2% on ImageNet, with a reconstruction fidelity (rFID) of 0.36, comparable to specialized representation learning models [11][12]. - Replacing the tokenizer in a standard diffusion model training with VTP led to a 65.8% reduction in FID relative to the baseline and a fourfold increase in convergence speed [12][13]. - This indicates that investing more computational resources in tokenizer pre-training can significantly enhance downstream generative quality without increasing the complexity of the generative model [13].

近年来，大语言模型在「写得长、写得顺」这件事上进步飞快。但当任务升级到真正复杂的推理场景 —— 需要兵分多路探索、需要自我反思与相互印证、需要在多条线索之间做汇总与取舍时，传统的链式思维 （Chain-of-Thought）往往就开始「吃力」：容易被早期判断带偏、发散不足、自我纠错弱，而且顺序生成 的效率天然受限。 北京通用人工智能研究院（BIGAI）语言交互实验室（NLCo）最新工作 Native Parallel Reasoner（NPR， 原生并行推理器） ，瞄准的正是这类瓶颈： 让智能体在一次思考中同时衍生并维护多条候选推理路径，并在关键节点「分支 + 聚合」，最终像拼图一 样汇总线索，合成最优解。 更重要的是，NPR 的突破点不只是「并行生成的工程技巧」，而是提出了一套「自蒸馏 + 并行强化学习」 三阶段训练范式，并配套专门的 并行推理引擎 ，目标是让并行推理从外挂变为模型的 原生认知能力 。 人们对语言智能体（Language Agent）的研究已经把关注从「单一思维链扩展」推广到了「多步深度推 理」。模型能够进行更深层次的推理令人兴奋，但未来的超级智能真正需要的，是 能更广泛地并行探索多 条可能 ...

机器之心发布 当 Agent 遇到工具调用错误时，错误日志里往往已经包含了解决方案 —— 正确的参数格式、有效的 API 用法、甚至是直接可用的替代方案。然而，静态 的 Prompt 无法让 Agent 从这些反馈中 "学到教训"，导致它们陷入 "错误循环"：承认失败，却重复同样的动作。 华为诺亚方舟实验室与香港中文大学联合发布的 SCOPE 框架，旨在解决这一问题。 SCOPE 的核心思想是：既然 Agent 会被反复调用，那么它的 Prompt 就可以在执行过程中不断进化。通过从执行轨迹中自动提炼指导规则，SCOPE 让 Agent 能够 "从错误中学习"，并将经验固化到 Prompt 中，实现自我进化。 Agent 的两大失败模式 研究团队分析了 GAIA 和 DeepSearch 基准上的 Agent 执行日志，发现了两类典型的失败模式： 论文：《 SCOPE: Prompt Evolution for Enhancing Agent Effectiveness 》 论文地址：https://arxiv.org/abs/2512.15374 开源地址：https://github.com/Jarvis ...
