I can barely get GitHub Copilot to output a functional 50 line program, let alone a 5 KLOC program that actually works.
Try Claude or Gemnini pro, copilot is like the dollar store steak of LLMs. Gemini will go up to 8K LOC if you really optimize the context, but that's about the limit. You can use it free in aistudio[1]
