Follow-up: gradient flow lets residual states encode information for far-future predictions

mlpowered · x · 2026-11-06

The follow-up half of mlpowered's exchange with antirez: because next-token prediction gradients flow back through attention to all prior residual states during training, these states can be updated to aid predictions many tokens ahead, supported by the papers he linked — further rebutting the claim that the last-token residual state is optimized only for the next token.
