- - It focuses on point forecasts, and does not support probabilistic forecasts. We experimentally offer quantile heads but they have not been calibrated after pretraining.

- 1. The context_len here can be set as the max context length **of the model**. You can provide shorter series to the `tfm.forecast()` function and the model will handle it. Currently the model handles a max context length of 512, which can be increased in later releases. The input time series can have **any context length**. Padding / truncation will be handled by the inference code if needed.
