AMERICAN
SUPER INTELLIGENCE INDEX
THE CAPABILITY SCALE FIELD GUIDE / 04
What does a score mean? Where do today’s leaders stand? A plain-language guide to the six stages.
The American Super Intelligence Index is a guide to what broadly available systems can do. We use Super Intelligence, or SI, as the name for the wider field. That does not mean every model on the board is already superhuman.
A score records capability at a particular moment. The current leaderboard is the October 14, 2026 snapshot. Each entry includes a score, relative speed and cost tiers, a recorded date, and an entry status. Nationality adds no points.
The stage names belong to this publication’s framework. They are not scientific certification, a safety rating, or a promise that a model will suit every job. Think of the scale as a guide to the horizon, not a guarantee.
The six stages describe increasingly broad, capable, and reliable systems. They are not a calendar. Equal spacing on the chart does not mean equal effort—or equal time—to reach the next stage.
The AGI Runway
Useful for reasoning, coding, writing, and working with tools, but still uneven. People need to set the direction, check the work, and step in when things go wrong. A brilliant answer is not the same as finishing a whole job reliably.
Human-Level General Intelligence
Broadly capable of human-professional work. A system can adapt to unfamiliar tasks, make a plan, use tools, and carry out several steps with limited oversight. This is a category on our scale, not independent certification of AGI.
Expert General Intelligence
Strong specialist ability across many fields. The system can match skilled human experts, outperform them in some areas, and carry insights from one field into another. The key is dependable expertise across a broad range of work.
Exceptional General Intelligence
Exceptional ability across most cognitive work, including original discoveries, designs, and strategies. Those results must hold up when checked. An intriguing idea alone is not a discovery.
Superhuman General Intelligence
Beyond the best individual human experts across virtually all cognitive work, with the reliability to manage complex, long-running projects. The next stage raises the bar from individual experts to coordinated teams.
Civilization-Scale Superintelligence
Beyond even large, well-coordinated groups of the best human experts across virtually all cognitive work. That is the General Super Intelligence threshold. It would not mean knowing everything or escaping physical limits. On our scale, 100 is a threshold, not a ceiling. No model on the current board reaches it.
The active board covers systems broadly available through a product, API, platform, or another public channel on standard terms. Private internal models, invitation-only research previews, and systems that need specially restricted infrastructure sit outside it.
A system withdrawn from public availability belongs in the historical record rather than the active board. This snapshot records the board as of October 14, 2026; it does not promise that every entry is still available today.
We write about American leadership, but nationality is not a scoring factor. And a five-model snapshot is not a survey of every system in the world.
No. It is a capability score on this index’s scale. It is not a percentage of progress, probability or timeline.
Yes, within a domain. Specialized depth and general breadth are distinct dimensions. A strong domain result does not automatically establish GSI.
No model in this index reaches the 100-point GSI threshold. This publication makes no claim that GSI has been achieved.
Yes. The public results JSON includes the recorded scores and metadata.
