Uni2TS is a PyTorch library for unified pre-training, fine-tuning, inference, and evaluation of universal time series forecasting transformers like Moirai and Moirai-MoE. It provides a research framework with pre-trained model weights and benchmarking utilities.

Use cases

• forecast future values of time series with pre-trained transformer models
• fine-tune a universal time series foundation model on my own dataset
• run zero-shot time series forecasting without training a model
• evaluate forecasting models on Monash, LSF, and PF benchmarks
• pre-train a time series transformer at scale
• compare Moirai, TimesFM, Chronos, and VisionTS forecasters

When to choose

• you need state-of-the-art zero-shot or fine-tuned time series forecasting
• you are researching universal time series transformer architectures
• you want pre-trained Moirai model weights with PyTorch tooling

When to avoid

• you need simple classical forecasting methods like ARIMA or Prophet
• your project is not Python/PyTorch based
• you need production low-latency serving rather than research workflows
