科创板人工智能ETF（588930）紧密跟踪上证科创板人工智能指数（950180.CSI）。该指数从科创板市 场中选取30只市值较大且业务涉及为人工智能提供基础资源、技术以及应用支持的上市公司证券作为指 数样本，以反映科创板市场代表性人工智能产业上市公司证券的整体表现。 消息面上，据界面消息，6月14日消息，腾讯宣布混元3D 2.1大模型对外开源。目前，混元3D模型在 Hugging Face下载量已超过180万。这也是首个全链路开源的工业级3D生成大模型，有望推动游戏开 发、影视制作、工业设计、虚拟仿真、数字孪生等多个行业的进步。 华西证券认为，在生成式AI及大模型的需求驱动下，客户算力需求由传统CPU通用算力向GPU、TPU等 智能算力演进。算力需求拉动国内外龙头公司算力开支持续提升。同时，DeepSeek蒸馏模型的出现， 将进一步促使物联网产业链向智能化、高端化方向演进，芯片企业针对边缘端AI推理芯片也有望满足 DeepSeek蒸馏模型在物联网设备上的高效运行能力，从而持续推动边缘计算需求。 6月16日，三大指数集体低开后震荡走高。截至发稿，上证科创板人工智能指数涨0.35%。 相关ETF方面，科创板人 ...

21世纪经济报道新质生产力研究院综合报道 早上好，新的一天又开始了。在过去的24小时内，科技行业发生了哪些有意思的事情？来跟21tech一起 看看吧。 【巨头风向标】 苹果部分Mac Mini存质量问题，产品无法开机 当地时间6月13日，苹果公司发布博文称，极少数搭载M2芯片的Mac mini（2023款）设备可能无法再开 机。受影响设备的生产日期为2024年6月16日至2024年11月23日之间。如果用户的Mac mini出现上述问 题，可使用序列号查询工具检查自己的设备是否符合维修计划的条件。若符合条件，苹果或苹果授权服 务提供商将免费提供检修服务。其他Mac mini型号则不在此服务计划范围内。Mac Mini是苹果公司推出 的小型台式电脑系列产品，初代Mac Mini于2005年1月上市。 我国成功开展首例侵入式脑机接口临床试验 近日，我国首例侵入式脑机接口的前瞻性临床试验成功开展，标志着中国在侵入式脑机接口技术上成为 继美国之后，全球第二个进入临床试验阶段的国家。该项研究由中国科学院脑科学与智能技术卓越创新 中心联合复旦大学附属华山医院，与相关企业开展合作。据介绍，该临床试验的受试者是一位因高压电 ...

Group 1 - Tencent announced the open-source release of the Mixyuan 3D 2.1 model at CVPR 2025, with over 1.8 million downloads on Hugging Face [1] - The German government discussed with NVIDIA CEO Jensen Huang the establishment of an autonomous AI infrastructure to enhance Germany's AI ecosystem, with plans for joint investments with industrial partners [1] - Boston Dynamics' Spot robots performed a choreographed dance on "America's Got Talent," impressing judges and advancing to the next round, showcasing the capabilities of their proprietary Choreographer software [1] - China successfully conducted its first invasive brain-computer interface clinical trial, marking it as the second country globally to enter this stage of clinical trials in this technology [1]

Core Viewpoint - Tencent's Mix Yuan 3D model has undergone a significant upgrade with the release of version 2.1, which is the first fully open-source industrial-grade 3D generation model, achieving industry-leading standards [2]. Group 1: Model Features and Performance - The Mix Yuan 3D model has surpassed 1.8 million downloads on Hugging Face, indicating its popularity and utility in the open-source community [2]. - The new version 2.1 has improved geometric generation quality and introduced PBR (Physically Based Rendering) material generation, enhancing the texture and lighting effects of 3D assets, moving away from a "plastic feel" [6][8]. - In user blind tests, the PBR textures of the Mix Yuan 3D 2.1 model outperformed RGB textures with a quality superiority rate of 78% [8]. Group 2: Accessibility and Customization - The Mix Yuan 3D 2.1 model has lowered development barriers by providing a fully open-source solution, including model weights, training code, and data processing workflows, allowing developers to fine-tune, retrain, or optimize the model for various customization needs [8]. - The model is compatible with consumer-grade graphics cards, enabling it to run on personal computers, thus broadening its accessibility for developers and researchers [8]. Group 3: Technical Enhancements - The new model optimizes detail modeling, resulting in higher mesh precision and better topological consistency, which lays the groundwork for subsequent texture mapping [8]. - It supports the generation of base color, metallicity, normal, and roughness maps, allowing for high-quality rendering of various complex materials such as leather, wood, metal, and ceramics [8].
