CoT vs Layer Looping: How Information is Actually Passed
inductionheads · x · 2026-08-03
Developer @Grad62304977 breaks down the core architectural differences between Chain-of-Thought (CoT) and layer looping.
He points out that the distinction lies in how information is propagated: layer looping passes information entirely within the final hidden state. In contrast, CoT passes information through the KV cache of each layer (e.g., across 70 layers) and routes it through attention mechanisms rather than a residual connection.
