> Frontier models can and do write readable, intelligible code

The problem is that even frontier models still are prone to regurgitation. They are not that capable of organization and relevance, which is part of why so much LLM output is insanely grating to read.

READMEs in particular are the worst. LLMs tend to regurgitate stuff like "what is located where" that is of zero relevance to the reader, especially if it's yet another bog standard Java, Symfony or React app.
