Frequently Asked Questions • Methodological Integrity
What is the AI Developer Ecosystem 100™?
The AI Developer Ecosystem 100™ is an independent, algorithmically computed index that evaluates platforms providing infrastructure, deployment, models, and tools for AI software engineering. It ranks entities based on seven dimensions, including Ecosystem Power, Momentum, Developer Utility, and Structural Defensibility.
How is the AKI Platform Intelligence Score™ calculated?
The composite score uses a deterministic formula: Score = 0.25(Ecosystem Power) + 0.20(Momentum) + 0.15(Developer Utility) + 0.15(Structural Defensibility) + 0.10(Platform Health) + 0.10(Trust) + 0.05(Openness). Daily score revisions are subject to a strict ±3.0 point evidence gate to protect against ephemeral marketing hype.
Why are Moat, Momentum, Health, and Dependency numbers reported separately?
To prevent double-counting. These metrics serve as diagnostic indicators. For example, a legacy package manager can maintain high systemic dependency and a defensible moat despite low growth momentum, whereas an AI coding agent may show high momentum with lower structural defensibility.
Does AKI receive preferential placement in its own index?
No. AKI is evaluated through the exact same automated ingestion pipelines and formula constraints, subject to the same ±3.0 daily volatility cap. In the September 2026 baseline, AKI ranks at #58 under the 'Emerging Challenger' regime with an Intelligence Score of 67.2.
How are parent companies and sub-products handled?
To avoid double-counting, the index enforces parent-child isolation. Sub-features that lack an independent developer graph are evaluated under their primary parent entity rather than as separate platforms.
