The Google Research\nTimesFM model is a foundation model for time-series forecasting that has been\npre-trained on billions of time-points from many real-world datasets, so you\ncan apply it to new forecasting datasets across many domains.\nThe TimesFM model is available in all BigQuery supported regions.\n\nUsing BigQuery ML's built-in TimesFM model with the\n[`AI.FORECAST` function](/bigquery/docs/reference/standard-sql/bigqueryml-syntax-ai-forecast)\nlets you perform\nforecasting without having to create and train your own model, so you can\navoid the need for model management.\nThe forecast results from the TimesFM model are comparable to\nconventional statistical methods such as ARIMA. If you want more\nmodel tuning options than the TimesFM model offers, you can create an\n[`ARIMA_PLUS`](/bigquery/docs/reference/standard-sql/bigqueryml-syntax-create-time-series)\nor\n[`ARIMA_PLUS_XREG`](/bigquery/docs/reference/standard-sql/bigqueryml-syntax-create-multivariate-time-series)\nmodel and use it with the\n[`ML.FORECAST` function](/bigquery/docs/reference/standard-sql/bigqueryml-syntax-forecast)\ninstead.\n\nTo try using a TimesFM model with the `AI.FORECAST` function, see\n[Forecast multiple time series with a TimesFM univariate model](/bigquery/docs/timesfm-time-series-forecasting-tutorial).\n\nTo learn more about the Google Research TimesFM model, use the following\nresources:\n\n- [Google Research blog](https://research.google/blog/a-decoder-only-foundation-model-for-time-series-forecasting/)\n- [GitHub repository](https://github.com/google-research/timesfm)\n- [Hugging Face page](https://huggingface.co/collections/google/timesfm-release-66e4be5fdb56e960c1e482a6)"]]
