someone sorted 1,018 research papers for 8 cents your agent spends more than that deciding what to do next which worker goes next, keep this tool call or drop it, is the draft ready. every one of those is a tiny decision billed like an essay jev by typesafe takes those forks off your frontier model for $0.000042 a decision and charges nothing for output every job leaves the fork on one of three lines: 1 → code, when the answer is exact. save the file, click the button, route the email 2 → the llm, when something actually needs to be written 3 → you, when confidence drops under 0.85 or anything is about to be published who's already riding it: browser use found flights in 7 seconds for $0.0039 riley brown triaged 500 emails for 3.5 cents alex volkov cut a claude session from nearly 1m tokens to 86k in a second langchain uses it to pick between cheap and smart models 10,000 decisions cost $0.42. the money was never in the decision, it was in a frontier model thinking out loud before every one i mapped the whole line in 10 stops, from the first fork you hand over to a working router on your own machine bookmark the full jev roadmap below before your next agent ↓
