What is the difference between artificial intelligence and synthetic intelligence?

Artificial intelligence is the established umbrella term for research and systems involving capabilities such as learning, perception, reasoning, and language. "Synthetic intelligence" is a less standardized expression whose meaning depends on the author or organization using it.

There is no universally accepted technical boundary separating the two.

Why the words can cause confusion

In ordinary language, artificial can mean human-made, but it can also suggest imitation. Some writers prefer synthetic to emphasize that a capability has been constructed rather than merely copied.

That preference is a framing choice. Calling a system synthetic intelligence does not by itself specify its architecture, training method, or level of capability.

AI also does not have to reproduce a human brain or imitate human behavior exactly. A route-planning system can solve a problem using methods that differ from the way a person navigates.

Look for an operational definition

If a product or article uses synthetic intelligence, ask what the term refers to in that context. Is it a branding label, a philosophical distinction, or a clearly defined technical approach?

For example, a vendor might use the phrase for an assistant that combines a language model with tools and memory. Those components can be described and tested directly, without assuming the new label defines a separate scientific field.

Separate terminology from evidence

Useful comparisons should examine the system's inputs, outputs, methods, and measured performance. Claims about reasoning or autonomy require relevant tests. Claims about consciousness involve additional unresolved questions.

The safest reading is therefore contextual: artificial intelligence has a broad established usage, while synthetic intelligence needs an explicit definition each time it is used. Neither label alone establishes what a machine can actually do.
