Lumentum Holdings Inc. (LITE) Debuts 400G PAM4 Optics to Boost AI and Cloud Networking Speeds

We recently published a list of 11 AI News Updates on Wall Street’s Radar. In this article, we are going to take a look at where Lumentum Holdings Inc. (NASDAQ:LITE) stands against other AI news updates on Wall Street’s radar.

China has sensed a window of opportunity in its race to usurp US dominance in AI innovation. As Washington remains focused on building regulatory walls that restrict access to AI, Beijing has resorted to fostering open-sourcing artificial intelligence models to boost AI innovation and adoption. That was clear when DeepSeek unveiled cost-effective AI models that challenged American tech dominance on large language models and data centers.

While the initial focus was on how DeepSeek came up with powerful AI models that rivaled US models, the focus has since changed to how the Chinese startup catalyzed the adoption of open-source AI models. The decision to open source AI source code comes as Chinese companies look to capitalize on growing opportunities in the artificial intelligence software market, growing at a compound annual growth rate of 35.52% and expected to be worth $223.35 billion by 2028, according to Research and Markets.

“DeepSeek’s success proves that open-source strategies can lead to faster innovation and broad adoption,” said Wei Sun, principal analyst of artificial intelligence at Counterpoint Research.

Understanding that it will require time for China to reach the level of the US in advanced AI computing, Chinese firms have concentrated on creating more efficient and cost-effective AI solutions. They are also striving to establish leading roles in open-source AI, cloud services, and worldwide data networks.

These approaches allow China to provide more affordable and unrestricted AI access to nations discontented with US policies, integrating it into developing markets in ways that will be challenging to disrupt. This is not merely a contest in AI; it is a struggle for dominance over the global digital infrastructure both now and in the future.

Since DeepSeek sent shockwaves, several Chinese companies have released open-source models that are free for individual users. The move to open-source AI models underscores a broader shift in China that no longer focuses on proprietary licensing. Instead, Chinese companies freely offer the underlying source code for modification and redistribution.

While US tech giants have always insisted on open-sourcing their models or source code, that has not always been the case in entirety, for starters, most US companies claim to use open-source code while still restricting their use and modifications. Other US companies generate revenue by charging people to access their models even on claiming they are open source.
