DeepSeek limits access to its AI model as demand strains capacity

DeepSeek, the Chinese startup whose artificial-intelligence model roiled global markets last week, said it would restrict access to its application programming interface service because of shortages with its server capacity.

In a posting on its website, the company said it suspended the ability of customers to top up their API credits to avoid any broader impact on their services. Any existing stored values won’t be affected, it added.
