Description: Detokenization is an early-layer two-stage mechanism where attention and MLP work together to reconstruct a token's original form from subwords. Attention provides a directional signal, and the MLP composes it with local embedding. This process is universal across twelve transformer models and its depth depends on positional encoding, allowing for linear prediction of success.
