Artificial superintelligence (ASI)

In plain English

Before 2026, writers used artificial superintelligence, or ASI, for a system that surpasses human intelligence across the board, and AGI for the earlier human level stage. ASI appears throughout the research literature, in company mission statements and in policy debates such as the Ban Artificial Superintelligence Act introduced in the US Congress in September 2026.

With Executive Order 14434 the US government adopted Super Intelligence and SI as its everyday terms. ASI and SI now refer to the same idea in most writing, and enterrsi.si treats them as synonyms. Older sources keep their original wording, and this encyclopedia quotes their titles as published. The two terms differ mainly in era: ASI comes from the research tradition, SI from the official vocabulary that followed the renaming. Both describe a system that would be far more capable than any person, which is why both appear in debates about control.

Why it matters for rogue SI

Many key sources on rogue SI risk, from Bostrom's book to the 2025 superintelligence statement, use the older term. Knowing both names makes the research and the new official language readable side by side.
