HOW WE BUILT THE FASTEST, CHEAPEST BROWSER AGENT WITH JEV

Summary from the TLDR Dev newsletter

IronBee Express uses Jev as a fast classifier for bounded browser decisions, calling an LLM only for writing, recovery, or failure explanations. Explored runs cost about $0.0042 for 20 actions, recordings can replay with no step decisions, and narrow verification questions helped a 130-run replay test reach 130 correct outcomes.
