# Prism

Prism is a leakage-free probabilistic forecasting ensemble developed by the Frontier Research and DeepTech Team at Birla AI Labs. Rather than training a new model, Prism combines the quantile outputs of several pretrained foundation models, learning how to blend them from a held-out validation window that never touches test data. The key insight is that different models have complementary strengths: learning a separate blend at each quantile level means the model best at the median does not have to be the model that covers the tails.

Further details on the approach and results will be released in a future public report.
