AI supercomputer

Nvidia shares have hit their first record high since May, pushing the chipmaker's market value close to $6 trillion and defying critics who warned of an AI bubble. The news comes alongside fresh product launches, including the $4,999 DGX Spark desktop AI supercomputer with 64 GB of memory, and attention on CEO Jensen Huang's own stake in the company. Discussion is also swirling around new AI models like Reflection's open-source release, which could shape demand for Nvidia's chips.
