Definition
Plain language
A phone-driving AI agent that does its step-by-step thinking silently inside itself instead of writing it out, so it acts faster while staying just as accurate.
As stated in the literature
A mobile agent that reasons in continuous latent slots refined in parallel (APLR) and regularized during training by a generative world-model head predicting next-screen features; matches explicit chain-of-thought quality at a fraction of the tokens and latency.
Why it matters: It shows a phone agent can keep the accuracy of step-by-step reasoning while responding much faster, which matters for snappy, real-time control of an app.
For example, asked to book a ride, it works out the needed taps internally and acts on the screen quickly instead of first writing out a long plan in words.
