ANTHROPIC LEAKED A FILE WHERE 5 AGENTS BUILD AN LLM SYSTEM DOING $2.4M A YEAR IN 60 MINUTES the build costs $2.20 once, and the product after it pulls $200K a month running on agents customer asks → Haiku classifies → Sonnet 5 answers → Haiku checks → the answer every request runs through three models for 3.6 cents, and the customer never notices there were three $299 from the customer against $14 to serve them - that's 21x on every typical user the belt carries 789,000 requests a month and doesn't stop at night or on weekends five agents built the whole thing in an hour and never came back $2.20 in against $2.4M a year out - that's over a million x but in every 200 users there's one who costs you $428 on a $299 plan he's not a scammer or a hacker - he just really loves your product without a rate limit he's the one quietly walking off with your margin while you stare at revenue every LLM product needs a rate limit before it needs a growth plan the build froze at minute sixty, the model bill grows with every new customer save this and paste it into Claude Code - let it build you this system ↓
