According to CoinMeta, Hark has launched a new generation of web operation model, Handoff², which is now available to all Hark Pro users. Compared to the previous generation, the overall speed of completing web tasks has doubled on average, with booking flights speeding up by up to 3.8 times, and long-term research tasks even exceeding 5 times faster. The new model was tested across 478 tasks on 238 websites, resulting in a task completion rate increase from 73% to 82%, a rise of 9 percentage points. The ability to process website verification codes has also improved by 80%. The web operation performance and speed of Handoff² surpass those of Claude Opus by 5.5 times. The accuracy difference between Handoff and High is less than 5%, but the speed at which tasks are completed is about twice that of High. Hark mainly improves speed through enhanced learning training, penalizing excessive reasoning, repetitive operations, and time-consuming steps during training, enabling AI to learn to perform multiple operations at once. Since its official launch in October this year, Handoff has accumulated over 5.6 million browser sessions and processed more than 20 million dollars in shopping transactions.
