What is Open source?

Simple definition

Software whose source code is made available under a license that allows inspection and, depending on the license, reuse or modification.

How it fits into AI

Open source is part of the larger AI ecosystem. Its exact role depends on the system, but understanding it helps you make better sense of AI products, technical discussions, safety claims, and practical workflows.

A real-world analogy

In AI, “open source” is often used loosely. A system may expose code, weights, or documentation under very different licenses.

Why it matters

Businesses need to check what is actually open, what the license permits, and whether the model can be used commercially or redistributed.
