I have a project to convert my multiplayer XNA game from C# to Javascript and to add networking to the game-play using LLMs.
They are far worse at it now than they were a year ago. They actually implemented the requirements (Though inaccurately) to the best of their ability a year ago. Especially Gemini.
Now they don't even come remotely close to implementing just the basic requirements.
The thing is, I'm giving them the entirety of the C# source code and spelling out what they should do.
This is the part they REALLY don't want you to say.
They can no longer train these models effectively and their performance is slipping. Late 2023 was the golden age.
