TL;DR for operators Stopping an unsuccessful browser agent early can reduce inference costs, but an agent exhibiting failure-associated behavior may still recover. Talavera and Eirinaki’s research1 turns short execution histories into 32 inspectable failure signatures that can inform termination decisions. On a held-out test set, a five-step termination policy saved 26.3% of tokens with 92% termination precision. It also prematurely stopped four of 124 successful runs, a 3.2% successful-task termination rate. ...
