Anthropic 发现 Claude 的隐藏思考空间 J-space

Anthropic says Claude developed a hidden “thinking space” by itself during training. It is called the J-space: a small set of internal patterns that show what concepts Claude has “on its mind,” even when it never says them. Example: Claude can silently think “spider” to answer “8 legs.” If researchers replace that internal pattern with “ant,” Claude answers “6.” So this is not just chain-of-thought text. It is silent internal activity.  > **引用原帖 Anthropic (@AnthropicAI):** > In neuroscience, global workspace theory holds that thoughts become consciously accessible when they enter a privileged workspace that’s broadcast across the brain. > Using a new interpretability technique, we found something similar in Claude: the J-space. https://t.co/sLu2JgYwOQ > https://x.com/AnthropicAI/status/2074185351304724498
