Vibe coding has taken over for frontend dev, but outside that narrow band of very visible coding, most models aren't great at more esoteric programming languages. Even Swift gives Claude trouble. So the reason to fine-tune is simply that the best newest models still remain bad at things outside their comfort zone (how human).
I take my quip both ways, so I would wager that even with finetuning, these models are only 1 generation ahead in esoteric language performance and therefore _still not very good_. Am I correct?
