    The run is vendor-reported and has no independent full-training audit or reproduction.

    Remaining uncertainty

    Run duration, energy, capital cost, fleet availability, and yield are not disclosed.

  2. EV-07qualifiesHigh confidence

    The model and execution plan were reshaped around NPU constraints, with cumulative interventions raising reported model FLOPs utilization (MFU) by 58.7 percent relative to the baseline.

    Quotation or reported data

    Table 5 reports a 58.7% relative MFU improvement, reaching 30.0% MFU on 6,000 NPUs; techniques include hierarchical all-to-all, recomputation, and host swapping.

    Counterevidence

    Thirty percent MFU still implies substantial unused peak compute, and no comparable counterfactual run is public.

    Remaining uncertainty

    The incremental burden caused specifically by controls cannot be separated from normal large-model engineering.

  3. EV-08supportsHigh confidence

    The official model card says Pangu Ultra was trained from scratch; the repository publishes roughly 1.47 TB of weights and documents a minimum 32-card Ascend serving setup.

  4. EV-09qualifiesModerate confidence

    BIS assessed that listed Ascend 910-series chips likely involved U.S. design technology, software, or equipment subject to export rules.

    This is an enforcement assessment, not a bill-of-materials audit of the Pangu fleet or CloudMatrix installation.

    Remaining uncertainty

    The precise origin and legal status of each chip and upstream component are not public.
