Claude's current ability to use computers is imperfect. Some actions that people perform effortlessly—scrolling, dragging, zooming—currently present challenges for Claude and we encourage developers to begin exploration with low-risk tasks. Nice, but I wonder why didn't they use UI automation/accessibility libraries, that have access to the semantic structure of apps/web pages, as well as accessing documents directly…
I wonder if the model has difficulties for the same reason some people do - UI affordability has gone down with the flattening, hover-to-see scrollbar, hamburger-menu-ization of UIs. I'd like to see a model trained on a Windows 95/NT style UI - would it have an easier time with each UI element having clearly defined edges, clearly defined click and dragability, unified design language, etc.?
I wouldn't be surprised if they are working off of screenshots, they still trained their models on having said screenshots annotated by said automation libraries, which told the AI what pixel is what.
