You're Probably Sleeping On Computer Use

Today, head of evals Mike Taylor published a Vibe Check of TypeSafe’s Jev, a new kind of model that responds to a fuzzy question with a probability rather than prose, letting your code act on the result directly. It can’t compete with a frontier model on capability but is fast and cheap enough to check work while it’s being done.

Mike is also the reason today’s issue is focused on computer use: Astra’s ability to operate apps by clicking, typing, and scrolling changed his mind about the model. Later, we explain why that happened, how the rest of the team harnesses computer use to check off tedious items on our to-do lists, and how to use AI to create a slide deck that looks the way you want it to.
