MOMENT-Small
MOMENT is a family of foundation models for general-purpose time-series analysis. The models in this family (1) serve as a building block for diverse time-series analysis tasks (e.g., forecasting, classification, anomaly detection, and imputation, etc.), (2) are effective out-of-the-box, i.e., with no (or few) task-specific exemplars (enabling e.g., zero-shot forecasting, few-shot classification, etc.), and (3) are tunable using in-distribution and task-specific data to improve performance.
For details on MOMENT models, training data, and experimental results, please refer to the paper MOMENT: A Family of Open Time-series Foundation Models.
MOMENT-1 comes in 3 sizes: Small, Base, and Large.
Usage
Recommended Python Version: Python 3.11 (support for additional versions is expected soon).
You can install the momentfm
package using pip:
pip install momentfm
Alternatively, to install the latest version directly from the GitHub repository:
pip install git+https://github.com/moment-timeseries-foundation-model/moment.git
To load the pre-trained model for one of the tasks, use one of the following code snippets:
Forecasting
from moment import MOMENTPipeline
model = MOMENTPipeline.from_pretrained(
"AutonLab/MOMENT-1-small",
model_kwargs={
'task_name': 'forecasting',
'forecast_horizon': 96
},
)
model.init()
Classification
from moment import MOMENTPipeline
model = MOMENTPipeline.from_pretrained(
"AutonLab/MOMENT-1-small",
model_kwargs={
'task_name': 'classification',
'n_channels': 1,
'num_class': 2
},
)
model.init()
Anomaly Detection, Imputation, and Pre-training
from moment import MOMENTPipeline
model = MOMENTPipeline.from_pretrained(
"AutonLab/MOMENT-1-small",
model_kwargs={"task_name": "reconstruction"},
)
mode.init()
Representation Learning
from moment import MOMENTPipeline
model = MOMENTPipeline.from_pretrained(
"AutonLab/MOMENT-1-small",
model_kwargs={'task_name': 'embedding'},
)
Tutorials
Here is the list of tutorials and reproducibile experiments to get started with MOMENT for various tasks:
- Forecasting
- Classification
- Anomaly Detection
- Imputation

Environmental Impact
We train multiple models over many days resulting in significant energy usage and a sizeable carbon footprint. However, we hope that releasing our models will ensure that future time-series modeling efforts are quicker and more efficient, resulting in lower carbon emissions.
We use the Total Graphics Power (TGP) to calculate the total power consumed for training MOMENT models, although the total power consumed by the GPU will likely vary a little based on the GPU utilization while training our model. Our calculations do not account for power demands from other sources of our compute. We use 336.566 Kg C02/MWH as the standard value of CO2 emission per megawatt hour of energy consumed for Pittsburgh.
- Hardware Type: NVIDIA RTX A6000 GPU
- GPU Hours: 48
- Compute Region: Pittsburgh, USA
- Carbon Emission (tCO2eq):
Hardware
All models were trained and evaluated on a computing cluster consisting of 128 AMD EPYC 7502 CPUs, 503 GB of RAM, and 8 NVIDIA RTX A6000 GPUs each with 49 GiB RAM. All MOMENT variants were trained on a single A6000 GPU (with any data or model parallelism).
