DeepSeek withholds latest AI model from US chipmakers including Nvidia

DeepSeek, the Chinese artificial intelligence lab whose low-cost model rattled global markets last year, has not shown US chipmakers its upcoming flagship model for performance optimization, two sources familiar with the matter said, breaking from standard industry practice ahead of a major model update.

Instead, the lab, which is expected to launch its next major update, V4, granted early access to domestic suppliers, including Huawei Technologies, the sources said.
