The planetary prediction engine (PPE) is an experimental capability within Google Earth AI that autonomously executes the full geospatial modeling workflow—from data discovery to model training—based on natural-language queries, delivering faster, higher-quality predictions across public health, food security, environmental risk, and socioeconomics. It operates in three stages (data selection, multimodal dataset curation with embeddings and anti-leakage checks, and automated model building) with safeguards to prevent leakage and overfitting, passing artifacts via opaque handles to avoid prompt-size issues. Benchmarks show PPE improves accuracy and timeliness across tasks (e.g., US health indicators, FEMA risk, Nigeria food-security downscaling, and DRC Ebola nowcasting), leveraging multimodal fusion of statistical covariates and foundation-model embeddings to reduce modeling time from weeks to minutes.
