Hark's new web agent wants to book your flights for 10x less
Brett Adcock’s startup Hark just unveiled Handoff, an autonomous agent that browses the web to book flights or order food. It claims a record 97.7 score on the Online-Mind2Web benchmark at one-tenth the token cost of rivals. Why it matters: True end-to-end web agents could replace repetitive browser work, though Hark conveniently compared it against last-gen models rather than GPT-5.6.
