Chinese fintech giant Ant Group is calling out U.S. tech leaders—such as Nvidia, Google, and OpenAI—for allegedly using apparently open-source tools as a smokescreen to trap developers in closed-source AI ecosystems. According to Ant Group’s global open-source AI landscape report unveiled at the Inclusion Conference on the Bund in Shanghai, companies are releasing frameworks and development toolchains (e.g. Nvidia’s Dynamo, or agent frameworks from OpenAI/Google) that are technically open but designed to work best—or only—with their proprietary models or hardware. The report contrasts that with practices in China: firms like Alibaba Cloud and ByteDance are said to open-source whole models (actual weights/designs) that developers can freely download and build on. Ant Group also points to market share data showing dominance by a few U.S. players—Microsoft holds roughly 39% of foundation-model/model-management platforms, and Nvidia commands some 92% of the data-center GPU market.

Key Takeaways
– Open in name only? U.S. firms are accused of releasing “open-source” tools that are deeply optimized for their own hardware/models, limiting true interoperability and keeping developers tied to their ecosystems.
– Chinese approach differs: Ant Group highlights that certain Chinese companies are more willing to open up full models, not just tools, enabling broader adoption and flexibility.
– Dominant market control: Significant share of foundational AI infrastructure (GPUs, model platforms, etc.) remains under control of a few U.S. players, reinforcing the feedback loop of lock-in.
In-Depth
In recent developments, Ant Group—a leading Chinese financial technology company—has drawn attention to a growing tension in the global AI ecosystem: the distinction between what is claimed as “open-source” and what functions as such in practice. At issue is whether open-sourced tools and frameworks released by U.S. technology giants truly empower developers, or whether they serve as strategic layers masking closed ecosystems that funnel usage toward proprietary models and hardware.
Ant Group argues that while tools like Nvidia’s Dynamo or agent frameworks from companies like OpenAI and Google are open-source in name, they are optimized (or even constrained) to work best with those companies’ own hardware or models. What this means is cross-platform or third-party alternatives are less effective, making it harder for developers to shift away or integrate other tools without substantial friction. According to Ant’s report, such practices effectively lock in developer loyalty—even dependence—while maintaining control over core AI model infrastructure and performance advantages.
On the flip side, Ant Group claims that Chinese firms such as Alibaba Cloud and ByteDance are taking a different route, open-sourcing entire model architectures and weights. This allows developers not just to use tools but to build, modify, and deploy on their own terms. Ant posits that this approach is contributing to global adoption—even among U.S. startups—of Chinese models, since flexibility and true openness make them attractive in constrained or cost-sensitive settings.
Furthermore, the report cites market share numbers to show that dominance remains heavily skewed. Microsoft is said to hold about 39% of the foundation models and model management platform space, while Nvidia controls approximately 92% of data-center GPU market share. These figures underline the asymmetries in infrastructure: even with open toolchains, power relationships embedded in hardware, speed, optimization, and ecosystem partnerships favor incumbents.
From a policy and innovation perspective, these developments raise key questions. Is “open source” becoming a marketing tool more than a commitment to open collaboration? Do developers really benefit if open tools strongly favor one hardware vendor? How should regulation treat claims of open-sourcing in AI when model weights or interoperability are limited? As AI becomes ever more central to economic competitiveness, standards and definitions of openness may need refinement—both in technical terms (interoperability, portability) and in commercial terms (licensing, model access).
For developers, the short-term implications are about freedom of choice and cost. Locked-in ecosystems can mean higher switching costs, reduced bargaining power, and potential risks if a vendor changes direction. Long term, the growth of diverse, genuinely open ecosystems could lead to innovation, faster diffusion of models, more competition, and less concentration of power. Whether U.S. companies will respond to Ant Group’s critique—by opening up more fully or continuing with a hybrid model of openness—remains to be seen. The global AI race now isn’t just about performance or scale; increasingly, it’s about trust, openness, and who gets to define them.
