SST trades lower bulk-prefill active-body count for higher decode active-body count relative to 47B classic. Under the paper's common analytical proxy, SST becomes cheaper than 47B once prefill weight exceeds 65.5% and cheaper than 63B above 13.4%; at a 75:25 prefill:decode mix it is estimated 6.7% below 47B and 31.6% below 63B.

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.
