Toto is Datadog's observability-oriented forecasting foundation model. The official model card positions it for high-dimensional, sparse, non-stationary telemetry, and reports strong results on BOOM while remaining competitive on broader benchmark suites. It is the most workload-specific model in the catalog when your data looks like production infrastructure metrics rather than clean academic series.

Model Classification

Family

Toto

Type

time series foundation model

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

Training Data

Over 2T points total: roughly 1T internal observability metrics, public GiftEvalPretrain and Chronos data, plus synthetic series; the official card states no customer data was used.

Recommended For

  • Infrastructure, observability, and telemetry forecasting
  • Sparse, noisy, high-dimensional operational metrics

Strengths

  • Built around real observability-like workloads rather than only clean academic datasets
  • Strong benchmark fit for BOOM-style evaluation

Limitations

  • More specialized than general-purpose forecasting families
  • May be less intuitive as a default pick for simple low-dimensional business series
