Tutorial Tutorial How To Get Started With Evolutionary Model Merging

Arcee AI's evolutionary model merging turns the search for a useful combination of models into an optimization task. In its MergeKit tutorial, the developer chooses source models, a merging method and evaluation tasks. The software repeatedly builds and evaluates combinations, then saves the recipe with the best score.

The example scores spatial reasoning and compliance with a chosen response format, with adjustable importance for each. Those choices define what the search rewards: the useful capability is automating experiments against an explicit objective, rather than manually guessing which combination will work.
