DeepSeek is the Hangzhou lab that reset the market’s assumptions about cost. Backed by the quantitative hedge fund High-Flyer and led by Liang Wenfeng, it delivered frontier-class reasoning and coding at a fraction of the training and inference budget the field assumed was required, and it did it with open weights.
That combination, strong models plus open weights plus disruptive pricing, is the whole story. Teams can self-host the weights for full data control, which sidesteps the residency question that comes with any China-based hosted API. For reasoning and coding on a budget, DeepSeek forced everyone else to re-benchmark.
