500M params | 2K context | $0.00025 per forecast

TimesFM 2.0 500M is Google's larger open TimesFM checkpoint for zero-shot time-series forecasting. It is a decoder-only patched transformer focused primarily on univariate point forecasting, with optional experimental quantile heads that Google notes are not calibrated after pretraining. On TSFM.ai it is served with a 2,048-point context budget and Google's coarse frequency buckets for hourly-through-daily, weekly-through-monthly, and quarterly-plus series.

Model Classification

Family

TimesFM

Type

time series foundation model

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

Training Data

TimesFM family pretraining corpus plus an added LOTSA subset listed by the official model card, building on the broader Google Trends, Wikimedia Pageviews, and synthetic mixture used by the TimesFM line.

Recommended For

  • • Long-context zero-shot forecasting with strong open-model baselines
  • • Workloads where point forecasting quality matters more than broad task coverage

Strengths

  • • Large open checkpoints with long context windows
  • • Efficient patched-transformer design with strong zero-shot behavior

Limitations

  • • Primarily a forecasting family rather than a general multi-task TSFM
  • • Quantile support is not the main identity of the family
