AI Engineer World's Fair 2026 — unofficial import demo

We are rushing towards a world where every single digital surface (email, calendar, messaging, …, every desktop app, every phone app, every web app) that was previously meant for humans is now managed by AI agents. Of course, there are technical challenges to be solved: - Model context windows haven’t increased in 2 years. And the digital world is OOMs bigger (the ultimate “big world hypothesis”) anyway, so how does one architect this? - A large part of the digital world (most of the web) does not have APIs available and requires agents to act like humans (consume pixels, output keyboard/mouse actions). - Human preferences and the digital world change, and require agents to maintain a dynamic memory and continually learn. But even if we could solve these problems, what does this world look like? - The digital world, particularly the web, was built for human consumption (and is often hostile to bots). - For a while to come, we will be sharing the digital roadways with these digital robots. - What does end-to-end encryption and privacy mean when the other “end” of the communication is an AI agent? The Yutori team has spent the last year building the world’s best computer use model (slightly better than Opus 4.6 and GPT 5.4 while being 2x faster and 4-5x cheaper on browser use tasks), converted the web into a webhook with Scouts (agents that monitor the web 24/7 for anything you care about), and are now releasing Yutori agent that expands from the open web to your most common digital surfaces. This talk will be grounded in Yutori’s learning from what it takes to build agents that are always on, taking us one step closer to the world where every digital surface is their playground.
