Super Intelligence, shortened to SI, is the term the United States federal government adopted on 29 September 2026 for the technology almost everyone else still calls artificial intelligence. The word is older than the policy, it means something specific to researchers, and the switch changes what federal documents say rather than what the software does.
The short definition

Two definitions are now in circulation, and they do not match.
The research definition. Among people who study this, superintelligence describes a system that outperforms the best human minds across essentially every field, including scientific creativity and social skill. The philosopher Nick Bostrom popularized that sense in his 2014 book of the same name. By that standard, nothing that exists today is superintelligent, and researchers argue about whether anything will be.
The policy definition. The executive order of 29 September 2026 uses "Super Intelligence" and "SI" as the names for the field itself, in place of "artificial intelligence" and "AI". Under that usage, the chatbot you asked a question this morning is SI, because every system previously called AI is now called SI in federal writing.
When you read the word, check which one the writer means. A White House document means the second. A research paper means the first.
How SI differs from AI, in practice
For the systems you actually touch, it does not. Here is the honest comparison.
| What people mean | What exists today | |
|---|---|---|
| AI | Software that performs tasks that used to need a person: writing, summarizing, classifying, predicting | Everywhere. Email filters, recommendation feeds, chatbots, resume parsers |
| SI, policy sense | The same software, renamed in US federal documents | The same systems, different label |
| SI, research sense | A system that beats the best humans at nearly everything | Does not exist, and experts disagree about when or whether it will |
So three answers to "is SI different from AI" are all defensible, depending on the question being asked. If you mean the products, no. If you mean the federal vocabulary, yes, the word changed. If you mean the research idea, yes, and nothing today qualifies.
Where the term came from
The idea predates the policy by decades. I. J. Good described an "intelligence explosion" in 1965, arguing that a machine capable of designing better machines would quickly leave human capability behind. Bostrom's book turned that argument into a research program and gave the word its modern currency. Labs took the framing seriously enough to name teams and even companies after it.
What happened in September 2026 was not a discovery. A government chose a word it preferred and told its own agencies to use it. The White House fact sheet sets out the reasoning, and CNBC reported the order and the accord six technology companies signed alongside it.
What the switch does and does not reach
It reaches: correspondence, public communications, policy papers and other documents produced by executive branch departments and agencies. A federal grant notice, an agency report or a job announcement on USAJOBS written after the order may say SI.
It does not reach: private companies, universities, news organizations, researchers abroad, or you. LinkedIn job ads still say AI. Textbooks still say AI. A team in Berlin or Bangalore writing about the same technology still says AI.
That split is the practical thing to carry away. One vocabulary inside the federal government, another everywhere else, for the same systems.
Which word should you use
Mirror whoever you are writing to.
- Applying to a federal role that uses SI in its announcement: write SI.
- Applying anywhere else: write AI, because that is what the posting, the recruiter and the search box all use.
- Writing for a general audience: write AI first and mention SI once if the context is government policy.
- Writing a research or policy paper: define which sense you mean in the first paragraph, then stay consistent.
We wrote a separate guide on the resume question specifically: AI or SI on your resume.
How to talk about it in an interview
Interviewers in late 2026 are asking candidates how they use these tools. The terminology question can come up as a trap or as small talk, and the answer is the same either way: be specific about the work, not the word.
A weak answer names the technology. A strong answer names a task, a tool and a result. "I draft first-pass summaries of support tickets with an AI assistant, then edit them, which cut my handling time by about a third" tells an interviewer something. "I am passionate about AI" tells them nothing, and swapping in SI does not improve it.
If an interviewer uses SI, use SI back. Matching someone's vocabulary is ordinary professional courtesy and costs you nothing.
Does any of this change your job
Not because of the word. The underlying systems kept doing what they did on 28 September. What changes a job is what the tools can actually do and what your employer decides to adopt, and neither of those moved on the day the terminology did.
Treat announcements about naming as news, and treat changes in what tools can do as something to act on. The two get reported in the same stories, which is exactly why they are easy to confuse.
FAQ
Is SI the same thing as AI?
In US federal documents, yes: SI is the new name for what those documents used to call AI. In research writing, no: superintelligence means a system that outperforms the best humans at nearly everything, and nothing today meets that bar.
Does superintelligence exist?
Not by the research definition. Current systems are strong at specific tasks and weak outside them. By the new federal definition the word simply applies to every system previously called AI, so the question becomes a naming question rather than a capability one.
Who decided to call it SI?
The executive order of 29 September 2026 directs executive branch departments and agencies to use "Super Intelligence" and "SI". Six technology companies signed a related accord at the same event, which concerns safety practices rather than vocabulary.
Do I have to use SI now?
No. The order binds federal agencies writing federal documents. Private employers, universities and individuals are free to use either word.
Will "SI" replace "AI" in everyday speech?
Nobody knows. Language follows usage, and "AI" has a decade of consumer habit behind it. Watch job postings in your own field: the day they start saying SI is the day it matters for your writing.
Where can I practice talking about this in an interview?
Use the interview answer generator to build a specific answer from your own experience, then say it out loud twice. Specific beats fluent.
