## Summary

Recent research has introduced an automated search pipeline aimed at optimizing heterogeneous 4-Expert Mixture-of-Experts (MoE4) architectures. Over the course of 28 days, the researchers generated a total of 4,463 candidate models and conducted evaluations on 1,021 of these models. This extensive exploration revealed a coverage bias towards the AirNet family of models, leading the researchers to propose enhancements in model selection processes and a revision of the model generator to address these biases.
