Bernstein analysts warn that rising conventional DRAM prices will soon pressure AI infrastructure costs.

Tencent's Weixin AI testing represents a significant step in its artificial intelligence development, according to Jefferies analysts. The company is conducting small-scale tests across messaging, search and shopping scenarios while partnering with JD.com and Meituan.
