Ari Weinstein

Ari Weinstein works on computer use at OpenAI, helping agents operate the applications people use every day. A co-founder of Sky, he previously worked on automation at Apple, where he presented Siri Shortcuts for developers. His work spans user-defined sequences of actions and AI agents that can navigate software on a user’s behalf.[1][2][3]

Weinstein sees computer use as a way for agents to work with existing software. In the Latent Space interview, he describes using it to automate a complicated meal-prep order and points to another use in coding: an agent can test the application it has just built, reducing the manual testing required from its user.[1]

Faster models are only part of the story. Weinstein points to accessibility information and direct access to the browser’s document structure as ways to give an agent more context than a screenshot alone. An app shot, for example, can expose information such as link destinations and text that may be truncated on screen. Agents can also write code to execute several actions together.[1]

He argues that the agent’s surrounding harness matters alongside the model: avoiding unnecessary waits and responding to browser events can make an automation faster. OpenAI brought computer use into its Agents API, allowing developers to build with the same implementation used by its own products.[1]

When possible, you want it to be event-driven.[1]

Weinstein and Conrad Kramer co-founded Workflow, an automation app that Apple acquired and developed into Shortcuts. In a 2018 Apple developer session, Weinstein showed how apps could expose actions to Siri and how users could compose steps in the Shortcuts app.[4][3]

After Apple, Weinstein co-founded Software Applications Incorporated, the company behind Sky, a natural-language interface designed to work across Mac apps. OpenAI acquired the company in October 2025 and brought its team into OpenAI. Weinstein connects the projects through a longstanding interest in saving people time by automating computer tasks.[2][1][4]
