DeepSeek, the Hangzhou-based artificial intelligence start-up, may have made another breakthrough that could disrupt the way AI models are trained in China.

Its innovative data format, UE8M0 FP8, could pave the way for home-grown graphics processing units (GPUs) to be deployed in training powerful models even though local GPUs are not as powerful as Nvidia’s.

China’s stock market investors were excited about the breakthrough, pouring money into local GPU developers such as Cambricon Technologies, a Beijing-based start-up with the potential to take on Nvidia in the Chinese market.

The company’s Shanghai-listed shares have doubled in the past month, with a 20 per cent single-day gain last Friday and another 11 per cent gain on Monday following DeepSeek’s statement last week that it had changed the format of data to fit “next generation home-grown chips to be released soon”

The frenzy was akin to January when DeepSeek sent shock waves across the US equity market. The little-known company, whose head office is in a commercial office tower serving banks and investment firms, was regarded as “the biggest black horse” in China’s AI landscape after it unveiled its V3 model in December last year and the R1 model in January. The two models were on par with the world’s best in terms of performance but they were developed at a fraction of the cost.

For its V3 large language model, DeepSeek said it used only 2,048 Nvidia H800 GPUs and that the total training cost was US$5.6 million.
