THE SWELL #21
SAIL Weekly Digest June 8–12 | Issue #21
This week orbited one question: who gets to wield the frontier? Anthropic shipped its most powerful public model behind its tightest guardrails ever, then loosened them under pressure days later. SAIL authors tracked the same current from every side — the economics, the agents, and the politics all pulling toward the same shore.
The Week in AI
Anthropic released Claude Fable 5, a public version of its locked-away Mythos model, then walked back covert capability limits after researchers accused it of “secret sabotage” — admitting it “made the wrong tradeoff.”
OpenAI confidentially filed for an IPO, a week behind Anthropic, targeting a September debut at a reported $730–850B valuation with Goldman Sachs and Morgan Stanley.
The Pentagon confirmed it is testing OpenAI and Google models to potentially replace Anthropic’s Claude in classified systems.
