Chronos-2 forecasts linked time series together, lifting skill scores 5.2 points over baselines
Most time series foundation models forecast each series on its own. Chronos-2 reads several series and their outside drivers, called covariates, from past data, infers how they relate, and returns probabilistic forecasts with no task-specific training. Across benchmarks it improves skill scores by 5.2 percentage points over the strongest baselines and win rates by 10 percentage points.
