An agent runs entirely on your phone, no cloud, and plays Space Invaders, perceiving the scene, predicting the aliens, and dodging bullets in a loop. Another solves the New York Times mini crossword with a constraint graph that backtracks when the fills stop fitting. These are experimental, and the Times is emphatic that its actual puzzles are made by people with no AI in the games. The hard part is the budget: a local agent has to plan its next move inside a single 16 millisecond frame, without draining the battery or starving the renderer, or you get jank. Shafik Quoraishee and Joanne Song use that to argue accessibility and difficulty should stop being separate toggles. Model the game as a continuous negotiation and they become two ends of one dial the agent tunes to you in real time: it watches eye gaze and shaky taps, resizes controls on the fly, and breaks a keyboard trap the moment it detects one, all on the device. Their closing bet is that the future of AI is not one giant centralized brain but billions of small local ones, each shaped by the person it runs for.
