Mistral releases its first time-series foundation model, Timestral: available in four variants ranging from 5 million to 209 million parameters, runnable entirely on CPU and ready to use out of the box.
Mistral AI has officially launched Timestral—the company’s first time-series foundation model (TSFM)—available in four parameter sizes: 5M, 28M, 123M, and 209M. It supports multivariate probabilistic forecasting, covariate-aware modeling, and long-context modeling. On the three major public benchmarks—GIFT-Eval, TIME, and fev-bench—Timestral achieves state-of-the-art zero-shot performance across the board; its largest model, with just 209 million parameters, tops all three leaderboards, while inference requires no GPU and can run on a standard server CPU with millisecond-level latency.
