200M (+ optional 30M quantile head) params | 16K context | $0.00025 per forecast

TimesFM 2.5 200M is Google's smaller and more deployment-friendly open TimesFM checkpoint. The official repo describes it as an upstream 16K-context model with an optional continuous quantile head, no frequency indicator requirement, and speed-oriented structural updates such as QKV fusion. TSFM.ai currently serves it with a 1,024-point hosted context budget, reflecting the compiled runtime configuration rather than the upstream theoretical maximum.

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

GiftEvalPretrain, Wikimedia Pageviews through November 2023, Google Trends through end-2022, plus synthetic and augmented data, as listed in the official model card.

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
