Signwl AI Adoption Index

Composition. The SAAI score is the arithmetic mean of three pillars, each on a 0–100 scale. Equal weighting is a deliberate methodological choice: no pillar is favoured a priori. Composite = (P1 + P2 + P3) / 3.

P1 · Frontier mix. The share of items in a region that run on GPUs at or above a fixed performance floor of 900 FP16 TFLOPS. The floor is set at v1 inception and does not move; new GPU generations that meet or exceed it join automatically, and existing frontier chips are never demoted. This design future-proofs P1: adoption can keep growing as new generations ship, rather than resetting each year.

P2 · Deployment mix. The share of items in a region classified as inference-tier GPUs (as opposed to training-tier or compute-tier). A higher inference share signals a market in deployment, not in capability buildout — a leading indicator of mature adoption.

P3 · Capacity tightness. Computed from paired SPOT and ON_DEMAND prices for the same GPU SKU in the same region. The regional spot discount is normalised to a 0–100 score using the formula 100 × (1 − spot_discount / cap), where cap is the 95th-percentile regional spot discount observed across the full SAAI history (recomputed daily). Tight markets — where spot prices approach on-demand prices — score high.

Regional & global scores. Regional pillars are computed on each continent's observation pool. The global score is computed directly on the worldwide observation pool — not as an average of regional scores. This avoids any judgement about how to weight regions of different size.

Coverage threshold. A region qualifies for SAAI inclusion on a given day only if it satisfies both data-depth tests: (a) the trailing 7-day average of paired SPOT+ON_DEMAND SKUs is at least 5, guarding the spot-pillar's stability, and (b) at least 10 distinct GPU components are observed in the region that day, guarding against a narrow basket where a single SKU's presence can swing P1 or P2 by double-digit percentage points. Regions that fall short are shown as "Insufficient coverage" rather than computed with a partial formula — the metric has one definition, applied consistently. As coverage grows, more regions can qualify.

Velocity. Reported in percentage points: the change in composite over a trailing 7-day and 30-day window. A reading of "+1.4 pp" means the composite rose 1.4 points over the period.

Data lineage. Every input flows from the same observation feed that powers the Signwl GPU Pricing Index (SGPI). No external benchmarks, no NVIDIA revenue proxies, no TAM scenarios — the score is composed entirely of what Signwl directly observes in the live cloud GPU market.

Inception. 2026-02-01, aligned to SGPI's base date. History from this date onwards is reported daily.
