A new analysis of foundation models for time series forecasting suggests that their deployment is not always justified. The study compared models like Chronos, Moirai, and Lag-Llama against traditional methods such as XGBoost across 30 benchmark datasets. While foundation models outperformed classical methods unconditionally on 15 datasets, on others, classical methods were superior with as little as 2% of the training data. The research also found that LoRA fine-tuning can sometimes degrade performance on shorter time series. AI
