In February 2025, the tech industry buzzed with anticipation, akin to a meticulously planned gathering. Tim Cook and Cai Chongxin clinked glasses, heralding Alibaba and Apple's AI collaboration. Meanwhile, Ma Huateng and Li Yanhong quietly positioned DeepSeek at the forefront of their strategies. Amidst the revelry, some bet on closed ecosystems, others on open-source revolutions, and yet others aimed to reshape the global AI landscape through strategic alliances.

Beneath this festive atmosphere lies both the anxiety of Silicon Valley giants and the ambitions of Chinese tech titans. DeepSeek, the disruptor, wields a sharp edge labeled "low-cost, high-performance," shattering the previously exclusive circle that was once the domain of a select few.

01. Common Ground: Triple Resonance in Technology, Ecology, and Market

Whether it's Alibaba and Apple's "hardware-software integration" or WeChat and Baidu's embrace of DeepSeek, the core lies in the shift of industrial paradigms fueled by AI technology. This transformation can be analyzed from three dimensions:

First, Technological Revolution: Low-Cost Models Redefine Business Logic. The rise of DeepSeek signifies a shift from an "arms race in computing power" to an "application efficiency revolution." As the reasoning cost of large models plummets, this "cabbage price" strategy attracts small and medium-sized developers alike, compelling giants to realign their strategies. Alibaba won Apple's favor with its Tongyi Qianwen series, deeply integrating AI into the iOS system. WeChat taps into the search needs of 1 billion monthly active users at nearly zero marginal cost through DeepSeek-R1. Baidu, on the other hand, abandoned the closed-source approach, responding with a "free + open-source" strategy.

Behind this technological dimension-reducing strike lies a crucial insight: while computing power remains vital, model efficiency holds the key to success. This is a natural consequence of diminishing returns from hardware investments and an explosion of software-layer innovation.

Second, Ecological Reconstruction: From Single-Point Breakthroughs to Network Effects. When DeepSeek welcomed access from over 200 companies post-2025 Spring Festival, an AI-centric ecological war quietly intensified. WeChat leverages its extensive high-quality content on official accounts to build a closed-loop "search as a service" ecosystem, enabling users to obtain answers directly rather than links. Alibaba aims to provide localized AI services for Apple through super apps like Alipay and Gaode Maps, achieving bidirectional empowerment through "technology output + data feedback." Even Baidu had to open its Wenxin large model, attempting to rebuild its moat with "deep search + intelligent agent platform."

These moves converge on a common goal: embedding AI into the users' full lifecycle and making the ecosystem the engine of the data flywheel. Just as WeChat expects to revitalize historical content through DeepSeek, Alibaba aims to reach 250 million iPhone users via Apple hardware, demonstrating that ecological synergy is redefining traffic distribution rules.

Finally, Market Reshuffling: C-End Experience Drives B-End Transformation. Both Baidu and Tencent sought to integrate DeepSeek's capabilities into their core businesses, recognizing the potential for scaling applications through enhanced model capabilities combined with their products. On the C-end, superior models, lower prices, more user-friendly interactions, and enhanced user experiences directly translate into larger user bases and higher engagement, indirectly boosting user willingness to pay and conversion opportunities. On the B-end, inherently strong in paid services and ROI, improved model capabilities drive increased token usage.

Moreover, DeepSeek's biggest impact lies in proving that the C-end user experience can directly disrupt the B-end market landscape.

For instance, as China's largest cloud service provider, Alibaba deploys the DeepSeek-V3 model to optimize customer service Q&A and product description generation in e-commerce scenarios, while exploring financial risk control applications. However, the C-end revolution sparked by DeepSeek compelled Alibaba to adjust its strategy: on one hand, collaborating with Apple to develop AI functions to seize hardware entry points; on the other, integrating C-end products like Quark, elevating AI-to-C business to a strategic level. This expansion from B-end infrastructure to C-end application scenarios reflects the passive transformation of traditional cloud service providers in the AI era.

Another example is Baidu's announcement on February 13, 2025, that Wenxin Yiyan would be fully free from April 1 and provide deep search functionality. This decision directly disrupts its original B-end charging model, reflecting a fundamental shift in business logic due to pressure from the scale of C-end users.

02. Characteristics: Three Paths, Three Survival Philosophies

Beyond common ground, despite sharing the underlying logic of technological revolution, the strategic choices of the three giants reflect distinct survival philosophies:

First, Alibaba and Apple's collaboration resembles a mutually beneficial partnership. The essence lies in an ecological swap between Apple and Alibaba. Apple leverages Alibaba's localized AI capabilities to address AI choices for the iPhone in the Chinese market, while Alibaba desperately needs a high-frequency entry point to regain users' attention - the AI-equipped iPhone serves as a "golden ticket" covering 250 million high-net-worth individuals.

For WeChat, accessing DeepSeek is an upgrade of its closed ecosystem. It's not merely a functional upgrade but a redistribution of power within the content ecosystem. By locking the answer source on official accounts, WeChat not only enhances creator stickiness but also transforms the search engine into an "in-station tool." The AI-recommended "demand insight" function shifts advertising placement from "wide casting nets" to "precision sniping," potentially reconstructing the entire commercialization system.

Imagine a scenario where 1 billion users habitually use WeChat to answer questions; its ecosystem would undergo a qualitative transformation from a "social platform" to a "life operating system."

As for Baidu, it exchanges technical openness for ecological vitality. By integrating DeepSeek, Baidu Search can reconstruct user value through AI-generated precise answers, shifting from traffic distribution to cognitive services. This synergy enables Baidu to swiftly establish differentiated advantages in vertical scenarios like healthcare and education. Furthermore, Baidu's vast user data feeds back to optimize the DeepSeek model, fostering a virtuous cycle of "data-model-scenario."

03. Conclusion: A Rational Path in the Technological Tide

Whether it's Alibaba's ecological grafting, WeChat's content closed loop, or Baidu's technological breakthrough, the crux lies in seeking new coordinates amidst the democratization of computing power. Apple's choice to collaborate rather than self-develop validates the value of localized data. WeChat's use of search to reconstruct its content ecosystem reveals the potential for reactivating existing resources. Baidu's embrace of open source exposes the fragility of closed systems. From the current perspective, there are no absolute winners in this transformation; only temporarily leading problem-solving approaches exist.

Hence, when the pace of technological breakthroughs outstrips the rhythm of commercial competition, perhaps the true key to success doesn't lie in who can build higher barriers but in who can first strike the balance between openness and controllability in the AI-driven transformation of the world.
