Overview
IBM's Granite TimeSeries TTM, also known as TinyTimeMixer, is a compact pre-trained model for multivariate time-series forecasting, containing less than 1 million parameters. Despite its small size, TTM outperforms several popular benchmarks that require billions of parameters in both zero-shot and few-shot forecasting scenarios. It is pre-trained on publicly available time-series datasets (~700M samples) and can be fine-tuned with minimal data to enhance performance. The current open-source version supports point forecasting use cases with resolutions ranging from minutely to hourly intervals (e.g., 10 minutes, 15 minutes, 1 hour). Notably, zero-shot, fine-tuning, and inference tasks using TTM can be efficiently executed on a single GPU machine or even on laptops, making it accessible for a wide range of users. The model is released under the Apache 2.0 license.
Highlights
- Despite having fewer than 1M parameters, the IBM Granite TimeSeries TTM outperforms larger models requiring billions of parameters in both zero-shot and few-shot forecasting tasks. TTM supports point forecasting across minutely to hourly intervals and is optimized for efficiency, allowing fine-tuning and inference on a single GPU or even a laptop. Its compact yet powerful design makes it ideal for scalable, real-world time-series applications.
- The IBM Granite TimeSeries TTM model is developed following IBM's AI Ethics principles, leveraging high-quality public time-series datasets with diverse augmentations to enhance forecasting accuracy. It is designed for accessibility and efficiency, enabling responsible AI use in time-series applications. Released under the Apache 2.0 license, TTM is available for both research and commercial use.
- The IBM Granite TimeSeries TTM model is designed for multivariate time-series forecasting across various domains. It supports point forecasting at different time resolutions, from minutely to hourly intervals, making it adaptable to a wide range of real-world applications. With strong zero-shot and fine-tuning capabilities, TTM enables businesses and researchers to develop precise, efficient forecasting models without requiring extensive computational resources.

Input data descriptions
The following table describes supported input data fields for real-time inference and batch transform.
Field name | Description | Constraints | Required |
|---|---|---|---|
inference_type | Must contain the value: "forecasting" | Type: FreeText | Yes |
model_id | The model to be used for generating a forecast.
Must contain the value: "ttm-r2" | Type: FreeText
Limitations: 1 ≤ length ≤ 256, Value must match regular expression ^\S+$ | Yes |
schema.timestamp_column | A valid column in the data that should be treated as the timestamp. Although not absolutely necessary, if using calendar dates (simple integer time offsets are also allowed), users should consider using a format such as ISO 8601 that includes a UTC offset (e.g., '2024-10-18T01:09:21.454746+00:00'). There are many date formats in existence and inferring the correct one can be a challenge so please do consider adhering to ISO 8601. | Type: FreeText
Limitations: 1 ≤ length ≤ 100, Value must match regular expression ^\S.*\S$ | Yes |
data | A payload of data matching schema (this input must be an object, not a string). We assume the following about your data:
- All timeseries are of equal length and are uniform in nature (the time difference between two successive rows is constant). This implies that there are no missing rows of data;
- The data meet the minimum model-dependent historical context length which can be 512 or more rows per timeseries; | Type: FreeText
Limitations: This input must be an object, not a string. | Yes |
