What this figure is

Calculated  Calculated from a published parameter count. Every model on this site is calculated the same way, so the comparison holds even where the absolute value carries uncertainty. Our figures are good to roughly a factor of two to three, which is why we only ever state a difference of 5× or more.

Is there a better choice?

A lighter model that does the job
Nothing we track is both at least as capable as Magistral Small 1.2 and meaningfully lighter. On our figures this is already a sensible choice for its standard of work.

What Mistral AI publishes

Energy cannot be worked out without knowing how big a model is. Of the 14 models from Mistral AI that we track, 13 can be assessed at all — the rest publish too little for anyone outside the company to calculate anything.
