Weight sizeno data

This snapshot holds needle2’s architecture but no weight size for any format, so the calculator cannot answer for it and it has no hardware table.

Why: Neither a published artifact nor a published parameter count exists for this model at its pinned revision. A size is never inferred from the model’s name.

The coverage page explains what the catalogue does not size, and why.
