browser-use open-sources Jev Ultrafast: web agent median task time cut to 7s
abhishek__AI · x · 2026-10-23
browser-use released Jev Ultrafast (23.5k GitHub stars, MIT license), billed as the fastest and cheapest web agent. Median task time dropped from 9.45s to 7.09s—e.g. booking a Zürich→London search on Google Flights from a single natural-language goal in 7.1s. Key design: 90% fewer protocol calls, 25% faster median execution, a dynamic indexed action space where the model picks an operation and element from an element table, text generation only on TYPETEXT, and no screenshots in the default loop—trading screenshot+LLM generality for speed and cost.
