AI Weekly Briefing: Anthropic Wins As OpenAI Pulls Back

A federal judge just told the Pentagon it cannot punish Anthropic for insisting on AI guardrails. Judge Rita Lin's injunction was unusually blunt, and it may matter more than any model launch this week. This episode covers what that ruling means if AI vendors can now push back on autonomous weapons and mass surveillance clauses without being frozen out of public-sector work, plus the immediate business stakes for defence buyers already using Claude. Then there's OpenAI's very different week. Sora is being shut down after reportedly burning around $1 million a day in inference costs - with peak daily costs reaching $15 million - against just $2.1 million in lifetime revenue. That retreat connects to a wider pivot: enterprise capability, data centres, IPO optics, and the upcoming Spud model. The question worth asking is what happens when cost pressure and thinner safety oversight arrive at the same time.
