The Depth Ceiling: On the Limits of Large Language Models in Discovering Latent Planning
Researchers discovered that large language models have a fundamental limitation in latent reasoning: they can discover multi-step planning strategies without explicit supervision, but only up to depths of 3-7 steps depending on model size and training method. This finding suggests that complex reasoning tasks may require explicit chain-of-thought monitoring rather than relying on hidden internal computations.
