arXiv:2609.15047v1 Announce Type: new Abstract: Xu, Vardi and Safran (ICML 2026) prove that over-parameterized ridge regression over an unstructured random Gaussian feature map groks, with the delay between memorization and generalization growing as $1/\lambda$ in the weight decay. We show that on a
OpenAI's ChatGPT, xAI's Grok, and Anthropic's Claude are back online after they all began experiencing issues around the same time on Thursday.

In a federal courtroom in California on Thursday, Elon Musk testified that his own AI startup, xAI, has used OpenAI's models to improve its own. The matter at question is model distillation, a common industry practice by which one larger AI model acts as a "teacher" of sorts to pass on knowledge to
"Distillation" is a hot topic as frontier labs try to prevent smaller competitors from copying their models.
Apple quietly threatened to kick Elon Musk's AI app, Grok, from its App Store in January over its failure to curb the surge of nonconsensual sexual deepfakes flooding X, according to NBC News. It was a muted show of force from one of tech's most powerful gatekeepers, made behind closed doors even as
