Plaintiffs seek a permanent injunction plus court-supervised destruction of infringing copies.

What it means

The $1.5B Bartz settlement covered acquisitions through August 2025 but didn't release output claims or works off the list. Same pirated corpus, different rights holders, demanding deletion rather than settlement.

Today’s Take

Three of today's five stories are the same story told from different chairs: what does a lab owe its customer when the customer is the state, the plaintiff, or the regulator. The Pentagon priced Anthropic's guardrails at zero and paid full freight to vendors without them. The labels are asking a court to price the training-data corpus and delete what can't be licensed. Bailey is asking the G20 to price the concentration itself. The bet that safety, licensing, and concentration are externalities the buyer absorbs is being unwound in three venues at once — and only one of them moves at software speed. Considered and passed: the Nvidia-MediaTek $3.5B chip deal (a supply-chain diversification, not a strategic reshape) and South Korea's record 2027 budget (headline number is the total, AI-specific line item not yet broken out).
