ANTHROPIC LEAKED A $4.5M SYSTEM THAT MICROSOFT AND GOOGLE RUN ON - MONTH ONE DOES $70K+ the whole stack costs $7 a month and holds a number 1,082× bigger than itself brief → spec → surface → payment → cron → review one agent, one context and zero handoffs between roles - there is nowhere for anything to get lost Opus 5 holds the brief and the spec, Sonnet 5 builds the surface and wires the payment Fable 5 writes the copy that used to cost a separate contractor a studio bills $70,000 and three weeks, the same scope in tokens costs $4.80 that's a 16,458× gap, and no meeting on earth closes it $79,000 is 264 customers at $299 or 16 at $4,900 - one number, different businesses the constraint was never the bill, the constraint is those 264 people the sixth spoke is red: the agent reviews itself and never argues with its own answer five dominoes stand in a row, and you set the first one get the first one wrong and it builds the other four perfectly on top of it the pulse beats every morning the same, whether anyone bought anything or not save this and paste it into Claude Code - let it build you these 6 steps ↓
