SOXL sinks 11%, OpenAI pulls models offline, and the semantic-cache PII trap

Om avsnittet

A rough week for chips, a big safety move from OpenAI, and why your semantic cache might be leaking PII. Markets: SOXL down about 11% to $83.56; QQQ down about 0.8% to $704.40; VGT roughly flat at $119.17; VUG down about 1.3% to $86.76.
