Court Strikes Down Pentagon's Anthropic Blacklist — Aug 29

A federal judge ruled the Pentagon's national-security blacklisting of Anthropic unlawful, the first legal check on the government's push to control who gets frontier AI. Z.ai shipped its long-delayed full GLM-5.3 open weights just as Google DeepMind piloted a double-blind evaluation method aimed at the self-reported-benchmark problem plaguing releases like it. Elsewhere, OpenAI cut Cursor's model access after its SpaceX acquisition, a new lawsuit accuses xAI of training Grok on child sexual abuse material, and Anthropic claims a steep cost cut in automating alignment research that remains unverified outside the company.
