The AI Code Generation Model Collapse: How Training on AI-Generated Code Is Breaking Every Model (With Detection Scripts)

Have you noticed your AI coding assistant getting… weird lately? Maybe it’s generating code that feels oddly repetitive, or producing solutions that work but seem unnecessarily convoluted. You’re not imagining things, and you’re definitely not alone.

We’re witnessing something fascinating and troubling in real-time: AI model collapse in code generation. It’s happening because models are increasingly training on code that was itself generated by AI, creating a feedback loop that’s slowly degrading the quality of outputs. Think of it like making photocopies of photocopies – each generation gets a little blurrier.
