This dated index is not a world-exhaustive ranking. Scores are benchmark estimates, not scientific certification of General Intelligence (GI) or General Super Intelligence (GSI).
THE CAPABILITY SCALE
America’s frontier.
The road to General Super Intelligence.
Six stages of general capability. One ambitious horizon.
SI = Super Intelligence · GI = General Intelligence · GSI = General Super Intelligence.
Current leader: OPUS 5.5 by Anthropic
Leader’s index stage: GI-I — Human-Level General Intelligence
26.1 / 100
AMERICAN SUPER INTELLIGENCE INDEX · GENERAL CAPABILITY SCORE
GI-I
Human-Level General Intelligence
Adapts to unfamiliar work, plans and completes multi-step tasks, uses tools and delivers broadly competent results with limited oversight.
GI-II
Expert General Intelligence
Matches strong human specialists across many fields, exceeds them in some and transfers insight between fields without losing rigor.
GI-III
Exceptional General Intelligence
Surpasses nearly every individual human across most cognitive work and repeatedly produces original discoveries, designs and strategies that withstand scrutiny.
General SI Runway
Superhuman General Intelligence
Exceeds the best individual human experts across virtually all cognitive work and sustains complex, long-running projects with extraordinary reliability.
GSI
Civilization-Scale General Super Intelligence
Surpasses even large, well-coordinated teams of human experts across virtually all cognitive work, operating at machine speed and scale.
100 marks the American Super Intelligence Index’s GSI threshold—not the ceiling.
This publication’s capability framework. Stage labels are not independent scientific certification. The scale maps capability—not calendar dates or percentage completion. Ranges include their lower limit and stop before the next: 20–<40 means 20 to under 40. 100+ means 100 and above. Benchmark snapshot: October 14, 2026. Wording updated October 29, 2026.

SEPTEMBER 29, 2026 / TERMINOLOGY DECISION
Super Intelligence enters the federal vocabulary.
Executive Order 14434 directs executive-branch communications to use Super Intelligence / SI wherever law permits, while initially retaining the statutory SI definition. The terminology policy does not mandate private usage or certify GSI.
