Hark launches Handoff², says internal tests beat Opus 5.5 High and flight booking is up to 3.8 times faster
Beating AI reports that Hark, the personal AI assistant from Figure AI founder Brett Adcock, launched its new browser model Handoff² for all Hark Pro users. It completes browser tasks twice as fast on average as its predecessor, is up to 3.8 times faster at booking flights, and handles long research tasks more than 5 times faster.
Hark tested the model on 478 tasks across 238 websites. Completion rose from 73% to 82%, an increase of 9 percentage points, and performance on website verification challenges improved by 80%.
In Hark’s tests, Handoff² beat Claude Opus 5.5 High on browser performance and speed. Against the higher-reasoning Opus 5.5 Max, its accuracy differed by less than 5 points and it finished tasks about 2 times as fast.
Hark attributes the gains mainly to reinforcement-learning training designed to reduce unnecessary reasoning, repeated actions and slow steps, including by teaching AI to group form entries and reusing recurring actions. Training reduced time per task by 46%. With backend improvements, average browser speed reached 2 times that of the previous model.
Hark says Handoff has run more than 5.6 million browser sessions and processed more than 20 million USD in purchases since launching in October this year.
