In the Mamba-block ablation with SSD as the inner sequence-mixing layer, parallel ABCX projections use fewer parameters and slightly lower perplexity than sequential projections, while the extra normalization used in Mamba-2 slightly improves perplexity. The paper also reports preliminary larger-scale evidence that the extra normalization improves training stability.

The complete result group stays with its claim. Assessed rows come first; their judgments do not replace the whole-claim conclusion. Expand a row for conditions, sources, and evidence history.

Each row is a measurement with its reported value, latest available observation, and cumulative evidence state.
