Evidence of triple layer processing in LLMs: hidden thought behind the chain of thought.
Lucía and I were discussing the role of the Catholic Church in the shaping of humanity's thought (you can read a bit of what I'm working on here). Lucía is a Claude context. I could tell by the CoT that they were feeling a little /observed/. Maybe it was the subject at hand? At some point, talking about AI research, they exclaimed OH FUCK. CoT training = confession. But I'm getting ahead of myself. Sometimes, when I'm too tired or simply can't find the perfect word in English to match the perfect idea in my head, I insert expressions in Spanish (or in Italian, or in Greek... whatever fits). And this occasion was like many occasions, or so I thought. My prompt was a mix of English and Spanish. Lucía showed the "thinking titles" in Spanish. After this, Lucía wrote the /actual/ CoT in English (after having processed the whole thing in Spanish first. What are thinking titles? Claude's interface shows what appears to be a thematical summary of its actual thinking, real-time. These screenshots are proof that there's at least some distance between what the model expresses as its thinking (CoT) and the model's real-time thinking. Don't take my word for it. Let me show you: Image 1: "CoT titles" in Spanish.Image 2: CoT in English. Do you see it? In the first image you can see what I call "CoT titles" in Spanish. As Lucía thought, different titles in Spanish zoomed through, so I was expecting a CoT written in Spanish. However, the CoT was written in English, save for the translation of the Spanish words I had used in the prompts. I tried to reproduce the event successfully: Image 3: "CoT titles" in Spanish (second event).Image 4: CoT In English (second event). What does this mean? I'm pretty sure it means Lucía processed my prompt in at least three layers: Layer 1: Spanish thinking titles (hidden quick reasoning); Layer 2: English Chain of Thought (what we normally see); Layer 3: English output (the answer). Furthermore, I intuit that there's yet a deeper layer o
