Jev Ultrafast books a Google Flights search from Zürich to London in 7.1 seconds
Jev Ultrafast: A browser agent with a dynamic, indexed action space

Jev Ultrafast is a browser agent that pairs TypeSafe's indexed action space with a small LLM. It picks one operation and one element per decision cycle, using a single network round trip, and only calls a text model when the operation is TYPE_TEXT. The result: a Google Flights search from Zürich to London in 7.1 seconds, with median task time cut 25% and browser protocol calls dropping from 1,092 to 101.
Give it one goal. TypeSafe's Jev picks an operation and an element. A small LLM writes text only when the operation is TYPE_TEXT.

The more I see about how Jev works, the less interested I get. Jev would be cool as a local model for e.g. Home Assistant. Projects like this are at best misleading, this one also happens to be broken.

“ Timing starts after initial page observation”
Isn’t this the part that takes most time?
