Interessting statement. I usually have to force Claude not to use GDScript and write C++ code instead. At least the Claude models from Opus and Sonet 4.6 appear to know Godot and GDScripting quite well.
I can understand that many people trying to use local LLMs get frustrated fast. I never got any usefull results from that either.
P.s. maybe I understood the quote above wrong. Making up for the programmer not knowing GDScript and Godot ? That would be something else.
