AI Slop Is in Your Training Dataset Now. I Tested Three Ways to Spot It.

# AI-Generated Content Is Sneaking Into Training Data—and It's Making AI Worse AI systems are being trained on content created by other AI systems (known as "AI slop"), which is degrading their performance. The problem is tricky because current detection methods often mistakenly flag real human-written content, and removing suspected AI content can actually make AI models less accurate rather than better. This creates a catch-22: companies can't easily clean up their training data without risking worse results.
