What this path costs, and what it does.
The card says what will launch. This page says what a launch actually did — one row per rented box, every number from a paid hour.
No cell measured yet.
The card is complete enough to launch, but nobody has rented a box for this path and recorded the result. An absent row is a measurement owed — never a zero, and never an estimate.
Why performance is not on the card.
A card is per weight path. Performance is per cell — the same weights on four cards is a different machine from the same weights on eight. Putting a number on the card would make one cell speak for every box the model could run on.
So the card carries a performance: link and nothing else. This page is
where the measurements accumulate: each launch against this path appends a row, and the
row names the box, the engine, the tensor-parallel width, and the price that hour
actually cost.
A cell that fails is recorded too. A path whose every launch failed is a different answer from a path nobody tried, and this page keeps them distinguishable.
