Time-LLM is a reprogramming framework to repurpose LLMs for general time series forecasting with the backbone language models kept intact. Notably, we show that time series analysis (e.g., forecasting) can be cast as yet another "language task" that can be effectively tackled by an off-the-shelf LLM.
- Time-LLM comprises two key components: (1) reprogramming the input time series into text prototype representations that are more natural for the LLM, and (2) augmenting the input context with declarative prompts (e.g., domain expert knowledge and task instructions) to guide LLM reasoning.

To install all dependencies:
pip install -r requirements.txt
You can access the well pre-processed datasets from [Google Drive], then place the downloaded contents under ./dataset
- Download datasets and place them under
./dataset
- Tune the model. We provide five experiment scripts for demonstration purpose under the folder
./scripts
. For example, you can evaluate on ETT datasets by:
bash ./scripts/TimeLLM_ETTh1.sh
bash ./scripts/TimeLLM_ETTh2.sh
bash ./scripts/TimeLLM_ETTm1.sh
bash ./scripts/TimeLLM_ETTm2.sh
Please refer to run_main.py
and run_m4.py
for the detailed description of each hyperparameter.
