Relationship, requires input

AI compute requires input AI accelerator

The stored status is what a reviewer approved. The level below it is what the overlapping data support; the two are shown side by side and only a human moves the status.

The edge as stored

AI compute requires input AI accelerator1 evidenceEstablished relation

AI compute depends on AI accelerator.

Mechanism

Training and serving large models runs on accelerators. Compute capacity is the number of accelerators installed times their throughput.

Confidence and strength are curated judgements recorded with the edge, not measured quantities.

Entity pages: AI compute, AI accelerator. Part of the mechanism AI compute demand pulls on accelerators, memory, leading-edge fabs, and the electricity and water those fabs use.

Statistical evidence

No analysis has been stored for this edge. The causal.analyze_all job runs monthly over every edge with a catalog metric linked to both entities; edges without a series on both ends are not analysed.

Not computed

Causal estimate

A causal estimate needs at least 20 overlapping periods and was not attempted for this edge yet.

What each rung means

Levels

Level 0: No association found
the overlapping data show no significant association.
Level 1: Correlation only
statistically associated in the overlapping periods; no direction, no mechanism.
Level 2: Predictive lead/lag
one series historically contains predictive information about the other.
Level 3: Mechanism supported
a documented physical, economic or institutional mechanism with cited evidence.
Level 4: Causally supported
a backdoor-adjusted estimate that survived refutation, on stated assumptions.
Level 5: Established relation
follows from engineering, accounting or scientific structure.
