Accuracy is items correct, %, with the paired difference from the base pipeline in points (the base pipeline's per-item records are the Phase 1 ones, which this box reproduces token for token). Passes per block and 30B expert loads per token (unique expert loads summed over layers &divide; generated tokens) are counted per item. Tokens per second = total generated tokens &divide; total decode seconds; base tokens per second is on the same items as rd, and speedup = rd &divide; base tokens per second on identical items (item count in brackets). Wall is the run's wall-clock time on 4 GPUs, start to finish, model load included. <b>Reproduction:</b> on this box the base pipeline reproduces the Phase 1 records token for token (HumanEval 164/164, MBPP 257/257, 12/12 on each sampled set), with the same adapter 35805974 and 30B revision c351bbc. Where the base pipeline was decoded on only the first 12 items, the speedup (marked <span class=flag>&dagger;</span>) pairs rd with the base on those 12 items and is <b>not fully measured</b>: on HumanEval and MBPP a 12-item speedup differed from the full-set answer by up to 13%, and the 12-item base alone has a bootstrap 90% range of &minus;6.5% to +8.0% (HumanEval) and &minus;3.8% to +3.9% (MBPP). Nothing in this table is extrapolated; Phase 1 box numbers are in section 6.</p>

      <p><b>Baseline.</b> The base pipeline was decoded here under the same 4-GPU load as rd: every item of the benchmarks that have a full base run (HumanEval and MBPP so far, plus any marked base in Table 0), the first 12 items of the others. On this box it reproduces the Phase 1 records token for token (HumanEval 164/164, MBPP 257/257, 12/12 on each sampled set), with the same adapter 35805974 and 30B revision c351bbc, so the work is identical across boxes. The 12-item baselines are small: per-item speed varies a lot, and a 12-item pairing on HumanEval or MBPP would have been off by up to 13% against the full answer.</p>
      <p><b>Cost model.</b> The Phase 2 cost model enters only the modelled 8-GPU wall times in section 6; no measured number on this page depends on it.</p>
      <p>Timing: per-item seconds are measured from before prefill to after the last forward with CUDA synchronized at both ends; no polling or sleeps are involved.</p>
