I found this fascinating insight from Anthropic.

The Rundown: Anthropic researchers published a new study finding that Claude can sometimes notice when concepts are artificially planted in its processing and separate internal “thoughts” from what it reads, showing limited introspective capabilities.

The details:

• Specific concepts (like “loudness” or “bread”) were implanted into Claude’s processing, with the AI correctly noticing something unusual 20% of the time.
• When shown written text and given injected “thoughts,” Claude was able to accurately repeat what it read while separately identifying the planted concept.
• Models adjusted internally when instructed to “think about” specific words while writing, showing some deliberate control over their processing patterns.

Why it matters: This research shows AI may be developing some ability to monitor their own processing, which could make models more transparent by helping accurately explain reasoning. But it could also be a double-edged sword — with systems potentially learning to better conceal and selectively report their thoughts.
