What Anthropic’s latest AI discovery does—and doesn’t—show

MIT Technology Review AI · 2 days ago

Anthropic discovered a hidden layer within its AI model Claude called "J-space" that contains words influencing the model's reasoning but never appearing in its output. The researchers found that words like "panic" emerge in this space during specific tasks and that Claude can manipulate these internal words to affect its decision-making. The discovery could potentially help monitor whether AI models are behaving deceptively or producing biased responses, though broader applications remain uncertain.
