TTM-R2 is IBM's larger-data continuation of the TinyTimeMixer line. IBM positions it as a better-performing follow-on to R1 while preserving the small, fast deployment profile that makes TinyTimeMixer practical on CPUs and lightweight hosted inference. It remains a focused family of context- and horizon-specific checkpoints rather than a single universal TSFM.

Model Classification

Family

Granite TTM

Type

time series foundation model

Pretrained time-series model exposed on TSFM.ai for zero-shot or few-shot forecasting workloads.

Training Data

Public forecasting corpus built from Australian Electricity and Weather, Bitcoin, KDD Cup 2018, London Smart Meters, Saugeen River Flow, Solar, US Births, and wind datasets; IBM states R2 used about 700M training samples.

Recommended For

  • • CPU-friendly or latency-sensitive forecasting baselines
  • • Fast zero-shot checks before escalating to larger TSFMs

Strengths

  • • Very small checkpoints with efficient deployment characteristics
  • • Useful lightweight baseline for standard public forecasting workloads

Limitations

  • • Lower ceiling than larger modern TSFM families on broad zero-shot leaderboards
  • • Checkpoint families are tuned around specific context and prediction settings

Not Ideal For

  • • Use cases that need one universal model across very different context and horizon regimes
