Mistral's Timestral is #1 by 0.003 MASE. I ran it — the model was not the variable.

Mistral released Timestral, four open-weight time-series models that top three benchmarks — by 0.003 MASE on their own table. I ran all three sizes against one-line baselines, on a known generator and on fresh Paris weather. With one summer of context the 209M lost to "repeat yesterday"; with three years it beat everything by a third — and the 20 MB model matched the 837 MB one.
