Software code that anyone can see, change, and share.
Open-source software means the underlying code is publicly available. Anyone can look at it, change it, and share their modified versions. This is different from proprietary software, where the code is kept secret.
For example, the Linux operating system is open-source. Many people have contributed to its development, and companies can use it freely in their products. This collaborative approach often leads to rapid innovation and widespread adoption.
Open-source refers to software whose source code is made publicly accessible under a license that permits users to view, modify, and distribute the code. This model fosters collaboration, transparency, and community-driven development. Common licenses include MIT, Apache 2.0, and GPL, each with different terms regarding modification and redistribution, especially concerning proprietary derivatives.
While open-source models offer flexibility and cost advantages, they can present challenges in terms of support, consistent performance, and ensuring safety or ethical alignment without dedicated oversight. The decision to use or contribute to open-source AI often involves weighing these factors against the benefits of community access and rapid iteration.
Open-source AI models and platforms are a growing concern for safety and security. Companies are developing tools to scan open-source code for vulnerabilities and are debating the risks versus benefits of public access to powerful AI.

The concept of open-source software originated in the free software movement of the 1980s, championed by Richard Stallman and the Free Software Foundation. The term 'open source' was later coined in 1998 to provide a more business-friendly framing. Source ↗
