TimesFM

Family overview — summarizes releases; licenses and availability belong to each release.

TimesFM (Time Series Foundation Model) is a family of pretrained time-series forecasting models developed by Google Research, first described in an ICML 2024 paper. Open checkpoints have been released as versions 1.0, 2.0, 2.5 (September 2025), and 3.0 (August 2026); version 3.0 adds native multivariate forecasting and native support for past-only and past-and-future covariates.1 4

Aug 2026 · License change
Google releases TimesFM 3.0 weights under a non-commercial license
Google Research released TimesFM 3.0, a time-series forecasting model, in August 2026 under the TimesFM Non-Commercial License v1.0 instead of the Apache 2.0 license used for earlier TimesFM weights. The license allows use of the weights only for non-commercial purposes and prohibits redistributing them; the repository says commercial and production use of TimesFM 3.0 is permitted through authorized Google Cloud services such as BigQuery ML. Weights up to version 2.5 and the TimesFM source code remain under Apache 2.0.

U.S. eligibility

Project eligibility rests on documented governing or maintaining entities, not on contributors.

Eligible · basis: Documented U.S. control

The repository and model cards credit Google Research, and the TimesFM 3.0 weights license is issued by Google LLC. Alphabet Inc.'s fiscal 2025 Form 10-K lists its principal executive offices in Mountain View, California, and Exhibit 21.01 lists Google LLC as a Delaware subsidiary of Alphabet.1 3 5 6
