A new research paper investigates how well two prominent time series foundation models, Chronos-2 and TabPFN-TS, integrate covariate information. The study found that TabPFN-TS is more effective at capturing simple relationships between covariates and the target variable, particularly for shorter prediction horizons. This suggests that Chronos-2's strong overall performance on benchmarks may not directly indicate superior handling of covariate dependencies. AI
