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
