Core Viewpoint - Morgan Stanley expresses skepticism about the practical implementation of the Doubao AI assistant, despite its impressive demonstration of features, and maintains a positive outlook on "super apps" like WeChat, Taobao, and Meituan [2][3][4]. Group 1: Challenges in Implementation - The Doubao AI assistant requires deep system-level integration, necessitating modifications to the operating system, which directly impacts the core interests of smartphone manufacturers (OEMs) [4][6]. - The successful implementation and promotion of the Doubao AI assistant depend on extensive technical collaboration and commercial negotiations with various smartphone OEMs, which poses significant challenges [7][11]. Group 2: Competitive Landscape - Major hardware players, including Apple, Huawei, and Xiaomi, are likely to develop their own AI assistants rather than collaborate with ByteDance, leaving limited options for partnerships with Doubao [10][11]. - The competitive environment in the Chinese market presents high entry barriers for Doubao to establish a broad hardware ecosystem [11][12]. Group 3: Investment Strategy - Given the difficulties in hardware breakthroughs, Morgan Stanley recommends investing in software application giants with substantial traffic and use cases, asserting that the dominance of "super apps" remains unchallenged [13][14]. - The report reiterates "overweight" ratings for Tencent, Alibaba, and Meitu, providing specific rationales for each: - Tencent is viewed as the best AI application proxy in China, with plans to launch its next-generation AI model, Hunyuan 2.0 [14]. - Alibaba is identified as the best AI infrastructure stock, with accelerating cloud revenue growth expected [14]. - Meitu is recognized as a beneficiary of AI multimodal capabilities, particularly in its "last mile" service capabilities that general AI assistants cannot fully replace [14].
