## TL;DR

Time-series forecasting is relevant to AI agents that plan capacity, monitor metrics, predict demand, or schedule content production. The safest public facts describe specific model families and benchmark claims rather than promising universal forecasting accuracy.

## Core Explanation

Forecasting tasks need careful temporal validation. A model that looks good with random train/test splits may fail when future data is separated from past data. For agent workflows, forecasting output should be treated as a decision aid with uncertainty, not as a command.

## Source-Mapped Facts

- N-BEATS is a neural architecture for interpretable time-series forecasting based on backward and forward residual links and basis expansion blocks. ([source](https://arxiv.org/abs/1905.10437))
- Informer uses ProbSparse self-attention for long-sequence time-series forecasting and reports O(L log L) time and memory complexity. ([source](https://arxiv.org/abs/2012.07436))
- GraphCast reports outperforming HRES on 90.0% of 1380 verification targets for medium-range global weather forecasting. ([source](https://doi.org/10.1126/science.adi2336))
