What this figure is

Day-one estimate  Calculated from an estimated parameter count — the maker hasn't published one. 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 Mixtral 8x7B 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.
