Hark launches Handoff²; self-tests show it outperforms Opus 5.5 High, delivering up to 3.8x faster speeds for flight booking.

Dongcha Beating AI Flash News: Figure AI founder Brett Adcock’s personal AI assistant Hark has launched a new-generation web operation model Handoff², which is now available to all Hark Pro users. Compared with the previous version, the new model doubles the average overall speed of completing web tasks, with flight booking tasks up to 3.8x faster, and long research tasks even over 5x faster. Hark tested the new model on 478 tasks across 238 websites, and its task completion rate rose from 73% to 82% (a 9-percentage-point increase). Its CAPTCHA handling capability also improved by 80%. According to Hark’s self-test, Handoff² outperforms Claude Opus 5.5 High in both web operation performance and speed. Compared with the higher-tier Opus 5.5 Max, the accuracy gap is less than 5 points, but its task completion speed is about twice that of Opus 5.5 Max. Hark mainly improved speed by optimizing reinforcement learning training: during training, it penalizes excessive reasoning, repeated operations, and time-consuming steps, teaching the AI to execute multiple operations at once, such as filling multiple form fields consecutively or reusing repeated action combinations. After training, the single-task time of the new model was reduced by 46%, coupled with backend optimizations, leading to an average overall speed twice that of the previous generation. Hark also disclosed that since its official launch in October this year, Handoff has run more than 5.6 million browser sessions and processed over $20 million in shopping transactions.
