Mistral Just Released the Best Forecasting Model (Timestral)
In short
The video evaluates Timestral, Mistral’s open-source foundation model for probabilistic, multivariate time-series forecasting, using Python and energy-demand datasets. It outperforms the tested alternatives, especially when using temperature as a covariate, while smaller versions offer faster local inference and browser or smartphone deployment.
Key points
- Timestral comes in 5M, 28M, 70M, and 209M-parameter versions.
- The model predicts probability distributions with 21 quantiles rather than single values.
- On one dataset, the 209M model achieved a mean absolute error of 3.192 versus Kronos 2 at 3.299.
- On the covariate dataset, Timestral reached an error of 59.8 with temperature versus Kronos 2 at 90.1.
- The 5M model ran locally in 0.83 seconds with an error of 3.318.
- The 28M model outperformed Kronos 2 on one test while remaining faster than the largest model.
- The 5M and 28M models can run locally in a browser, including on smartphones, through ONNX conversion.
