Hark claims that its browser use agent is faster and cheaper than competition.
Hark, a well-funded startup, has previewed a browser agent called Handoff that can complete online tasks by navigating websites and interpreting visual information to determine when to click buttons or enter information. The agent can handle websites without official APIs, such as those for shopping, dining reservations, and travel bookings, and the company claims it works faster and costs less than competing models. Multiple tech companies and startups are developing similar computer-use agents, making this part of a broader competitive landscape in AI task automation. Hark plans to release the agent by the end of summer and is currently accepting waitlist signups.

Long-running agents accumulate state that no transcript captures. A coding agent at step 10 holds edited files, a running dev server, installed packages, and a warm prompt cache. When it misreads a traceback and rewrites a file that was already correct, neither available recovery path is cheap: patching forward grows the context and the token bill, and restarting from step one re-pays every model and tool call while reproducing nothing exactly, because runs are non-deterministic. Jumping back t

New AI toolbars and prompts are showing up in Google Docs and Gmail. If you don’t want Gemini’s help in writing documents and emails, here’s how to turn that stuff off.

In October 2025, a storm brewed over the Caribbean Sea. Weather models differed on its trajectory. Would it remain weak and end up in Haiti, or would it intensify and head to Jamaica? Artificial intelligence model WeatherNext, developed by Google’s DeepMind and Google Research, went with the latter. Five days before landfall, it predicted with 80 percent confidence that the storm system would hit Jamaica as a Category 5 hurricane. Hurricane Melissa was catastrophic, causing flooding and landslid
