AI Weekly Briefing: Washington Decides Which AI You’re Allowed To Use

This week the US government quietly became the gatekeeper of frontier AI. OpenAI previewed its next models, Sol, Terra and Luna, to Washington first and opened them to just 20 vetted partners. Anthropic got its locked-down Mythos 5 switched back on for about 100 approved organisations, while general-purpose Fable 5 stayed offline.  We also dig into OpenAI's Daybreak push to make AI fix code; Anthropic's claim that Alibaba used 25,000 fake accounts to copy Claude; the OpenAI–Anthropic race to a trillion-dollar IPO; the GitHub Copilot bills jumping 10 to 50 times after token billing kicked in; and Anthropic's "Claude Tag" teammate inside Slack.  If you found this useful, follow the show and leave a rating.
