Comparing routed and monolithic approaches directly is a valuable direction to investigate and the team provided a good starting point with their evaluation framework!

Some things that could make this project stronger:

* Add statistical analysis (sample sizes, significance tests); observed differences are small enough that this is necessary

* At least as important: Make your dataset big enough that your scores become robust

* Validate the judge model itself through human evaluation

* Provide dataset details when you write up your work (sample size, domains covered, generation process)

A more ambitious and even higher-impact direction of improvement: Perform a mechanistic analysis of routing decisions to gain insights into which models were selected and why.

Thank you for your submission. It is well written, with some good results from comparing two base models and the Martian router.

The matrix score diagrams would be easier to read if normalized against say the “router” values so it is easier to see better/worse. Figure descriptions need to “stand alone” and be fulsome in case the reader skim reads the paper.
