Hark 声称其浏览器代理性能超越 GPT-5.5 且成本更低
hark 发布了 hark handoff，这是一个无需 api 即可在 target 和 linkedin 等网站导航的浏览器代理。hark 声称其代理比 gpt-5.5 和其他模型更快、更便宜，标志着转向经过后期训练的动作预测架构。
hark launched hark handoff, a browser-based agent designed to automate tasks on platforms like target, linkedin, and walmart by analyzing visual structure rather than relying on apis. the company claims its post-trained model, which predicts specific mouse and keyboard actions, offers performance superior to gpt-5.5 and opus 4.8 at a lower cost point. this approach challenges the dominance of general-purpose llms by prioritizing specific action-prediction over token generation for computer use. hark plans to move to pre-training later this year and opened a waitlist for availability by the end of summer.
