Granite Time Series TTM R3

Granite TTM R3 is a forecasting release built from compact TinyTimeMixer models. A lightweight router selects or blends experts based on the input series. The full models range from 1M to 35M parameters.

Model design and output

The family uses linear and mixing components rather than full self-attention. It supports zero-shot forecasting, few-shot adaptation and full fine-tuning. Multivariate inputs and external variables can inform forecasts. Parameter ranges describe the expert collection, not one fixed checkpoint.Granite Time Series TTM R3 model card

Practical use

Practical guidance. Select a forecast horizon and data frequency before comparing experts. Use a chronological holdout so future observations cannot leak into the input. Assess forecast error against a simple seasonal baseline, then check whether external variables are actually known at prediction time.
