Biomedical world models: a framework for virtual drug trials, intervention design and planning
marinkazitnik · x · 2026-09-18
Researcher Marinka Zitnik lays out how world models apply to biomedicine. Tracing the idea from Kenneth Craik to robot planning, RL, and recent work by Ha & Schmidhuber and LeCun, she contrasts three domains: games (cheap evaluation, Dreamer collecting Minecraft diamonds), robotics (Cosmos and V-JEPA 2 pretrained on video, adapted with little robot data), and driving (GAIA-1 simulating rare scenarios). Biology resembles the latter two — data collection is expensive, interventions rare or unsafe, and measurements often destroy the system. The framework enables simulating treatments on the same virtual patient, reverse-designing interventions toward target states, and sequential treatment planning.
