Amazon quietly open-sourced a time-series model that forecasts out of the box.

No training. No feature engineering. Point it at your data and it predicts.

It’s called Chronos — and it treats forecasting the way a language model treats text.

Let me break it down

Chronos-2 is a pretrained model capable of handling univariate, multivariate, and covariate-informed forecasting tasks in a zero-shot manner

Chronos 2 implements a pipeline that internally normalizes the time series, tokenizes, and produces forecasts using the architecture below.

Forecasting with Chronos 2 in 7 lines of code:

Companies don’t want another ARIMA model.

They want engineers who can build forecasting systems that actually ship to production.

Google Research releases TimesFM 2.5, an open-source time-series foundation model for forecasting, with 200M parameters, 16k context length, and support for quantile forecasts up to 1k horizon. The model is available on PyPI and Hugging Face, with fine-tuning via LoRA and integration into Google products like BigQuery ML, Google Sheets, and Vertex Model Garden.
