ALT Overview of our sleep framework: Input streams from the active phase are stored in short-term memory before entering the sleep cycle, which bifurcates into Consolidation (transferring fragile short-term tokens into expanded long-term parametric memory using low-rank structures and MoE) and Dreaming (autonomous self-improvement via synthetic routing with random experts and RL refinement).

ALT An overview of our iterative hybrid coding framework. The human icons illustrate where humans perform tasks in this framework. “Defn.” stands for the definition of the code.

ALT The Nexus AI device screens chest X-rays for lung diseases like TB in as little as 45 seconds.

ALT Our blind sweep model, trained on 1,968 participants (North Carolina, US, and Zambia) was fine-tuned on scans from 120 participants from Chicago, Illinois. It was then tested prospectively in Chicago (n=192) and Nairobi (n=193), with no fine-tuning on Nairobi data. The model was non-inferior to expert sonographers at determining gestational age, in both settings, with a combined mean absolute error of 4.18 vs. 4.48 days.
