Vision AI in 2025 — Peter Robicheaux, Roboflow
AI Engineer· 2025-08-03 17:45
[Music] I'm going to be giving a quick presentation about the state of the union regarding AI vision. Um, so I'm Peter Robisho. I'm the ML lead at Rooflow, which is a platform for building and deploying vision models.Um, so a lot of people are really interested in LLMs these days. So I'm trying to pitch why computer vision matters. Uh so if you think about systems that interact with the real world, they have to use vision as one of their primary inputs because the the built world is sort of built around vis ...
