New Models: Datadog Toto 2.0
Datadog's Toto 2.0 observability forecasting family joins the hosted catalog
#Datadog Toto 2.0
We have added four Toto 2.0 checkpoints to the TSFM.ai hosted catalog:
Datadog/Toto-2.0-4mDatadog/Toto-2.0-22mDatadog/Toto-2.0-313mDatadog/Toto-2.0-1B
We are not hosting Datadog/Toto-2.0-2.5B at launch.
#What's new
Toto 2.0 is Datadog's current-generation observability forecasting family. It moves Toto from a single 1.0 checkpoint to a scaling ladder with u-muP-style training, alternating time/variate attention for multivariate telemetry, and direct quantile forecasts for uncertainty bands.
#Availability
Toto 2.0 is available through the forecast API and model pages now. Datadog/Toto-Open-Base-1.0 remains hosted for compatibility, but its model page now marks it as legacy and notes that TSFM.ai plans to deprecate it for new zero-shot usage after Toto 2.0 production validation.
