it across its parallel slots, so the number one request may use is the smaller

<p class="note">The memory figure is the weights plus half again for the KV pool
plus two for the engine — an estimate, and editable. It is filled in rather than
left blank because a CPU profile has no card to be short of: with no figure,
every ready node is a candidate and the first one picked is whichever the
scheduler reached, not whichever can hold the model. A node label does the same
job by name if you would rather pin it.</p>

knows which models use it.</p>

what is listed here even if the branch moves in between — and a single file's

version and the old weights stay where they are.</p>
