How China’s AI Start-ups Are Rewiring the Way Models Remember

Faced with tightening chip supplies, China’s emerging AI companies are taking a new path, reprogramming the algorithms behind their large language models (LLMs) to achieve more with less. Rather than relying solely on expensive high-end semiconductors, these firms are betting that smarter architecture can compensate for limited hardware.
As access to advanced computing components narrows under global export restrictions, Chinese developers are focusing on a fundamental weakness inside today’s AI systems: the way models process and remember information. Their goal is to remove the “algorithmic bottleneck” that makes scaling large models so costly.
At the heart of this effort is the “attention mechanism,” the neural process that allows an LLM to determine which parts of previous data are relevant to a new input. The standard “full attention” method requires the system to compare every new token of data with all those that came before it. While effective, this method becomes exponentially more demanding as the dataset grows, pushing memory and processing limits to their extremes.
Start-ups such as Moonshot AI and DeepSeek are working on more efficient, hybrid forms of attention that reduce this computational burden. Their experiments include adaptive attention layers and memory-optimized retrieval systems that enable models to focus selectively on key data instead of recalculating every connection.
Developers say these innovations could help local AI firms compete globally without needing the same level of hardware muscle as U.S. tech giants. “It’s not only about chips anymore; it’s about how smartly you use them,” one researcher from a Beijing-based lab told domestic media this week.
The new generation of models emphasizes energy efficiency and resource optimization, crucial factors as training costs skyrocket. By redesigning internal memory functions, Chinese engineers hope to close the performance gap with leading Western systems, even as hardware constraints persist.
Industry analysts note that this algorithm-first approach could redefine China’s competitive edge in AI. If successful, it may allow the country’s start-ups to advance in foundational model development without depending heavily on imported chips.
For investors and policymakers, the shift signals a broader technological pivot: from scale-driven growth to efficiency-driven innovation. The outcome could influence not only China’s AI trajectory but also the global architecture of future intelligent systems.
As one Shanghai-based venture capitalist put it, “Hardware limits have forced creativity. What used to be an obstacle is now an opportunity to rethink how machines learn and remember.”
