Inquiry About Multivariate Time Series and Covariate Support in Chronos

[Claire-bx]

Dear Chronos Team,

I hope this message finds you well. I have a couple of questions regarding the Chronos framework:

Does Chronos currently support multivariate time series prediction (i.e., multiple IDs simultaneously)?

I noticed that the latest ChronosX mentions the ability to use covariates as input, but I could not find guidance on how to use them. Does this mean that, at present, the models available for zero-shot or fine-tuning can only perform historical sequence → future sequence prediction and cannot incorporate covariate inputs?

Thank you very much for your time and assistance. I look forward to your guidance.

autogluon has a higher level api that allows for covariates using regression and fine-tuning of chronos. Also, the predict method allows for multiple different "item_id" values to perform batch inference across multiple time series.
