Do you have citations? Everything I’ve read have said they have an overwhelming bias to Python; eg https://arxiv.org/html/2503.17181v1 and https://arxiv.org/html/2505.13004v1

Agents love writing Python, but it turns out they're not amazing at it. https://autocodebench.github.io/

I’m not really sure how to read those charts, but it’s completely possible that python did not work well for the approach they were trying.

I would be the first person to give up python for kotlin or some other more natively typed higher performing language. But the python bias is so far too big to ignore.
