In this tweet (https://twitter.com/ajeya_cotra/status/1684358475416064001?s=20), Ajeya Cotra (admirably) predicted that there's >50% chance >50% of the tasks in the newly announced WebArena benchmark will be solved by a single agent. Note that Ajeya didn't specify that a single agent had to solve all of them but I will resolve based on that, so there is the possibility of divergence.

  2. pixel-based screenshot

  3. accessibility tree of the webpage. Seems like this is a subset of the html DOM tree
