In this case I don't think zero-shot means no context. I think it's more used in relation to fine-tuning the model parameters over your data.

> TTM-1 currently supports 2 modes:

> Zeroshot forecasting: Directly apply the pre-trained model on your target data to get an initial forecast (with no training).

> Finetuned forecasting: Finetune the pre-trained model with a subset of your target data to further improve the forecast
