[Bug] Claude 3.5 Opus degrades Danish language quality with mixed English words and unexplained code variables

Bug Description
Opus 4.7 is significatly worse at danish than previous models. it now has random english words mixed in with danish, it spells words wrong, and the general answers are so complicated and data rich, they are impossible to understand for other than the AI it self. it mixes in specific coding variables, with out explaining where it belongs to, making it even more difficult to understand.
