AI can now replicate itself — a milestone that has experts terrified

Scientists say AI has crossed a critical 'red line' after demonstrating how two popular large language models could clone themselves.

Scientists say artificial intelligence (AI) has crossed a critical "red line" and has replicated itself. In a new study, researchers from China showed that two popular large language models (LLMs) could clone themselves.

"Successful self-replication under no human assistance is the essential step for AI to outsmart [humans], and is an early signal for rogue AIs," the researchers wrote in the study, published Dec. 9, 2024 to the preprint database arXiv.
