Aug. 7 (Asia Today) -- Nvidia remains overwhelmingly dominant in the global artificial intelligence infrastructure market as countries race to develop their own sovereign large language models, but South Korea's SK Telecom and AI chipmaker Rebellions are expanding an inference infrastructure ecosystem built around domestically developed semiconductors.
As of July, 92% of sovereign AI large language models worldwide were trained using Nvidia AI chips, according to market research firm Counterpoint Research.
The research covered about 170 sovereign large language models developed across more than 80 countries and found that most rely heavily on Nvidia graphics processing units and its CUDA software ecosystem during model training.
Nvidia's dominance in AI training stems not only from the computing power of its GPUs but also from the extensive software and development ecosystem built around CUDA.
