So, as a leading and responsible AI development company in New York City, we have compiled a list of the top 10 open source AI libraries. This list will help developers and businesses understand AI and ML Technologies and seamlessly integrate them into their operations.

Artificial Intelligence (AI) and Machine Learning (ML) are rapidly changing the digital landscape of the world. Therefore, businesses are also in a hurry to add AI to their operations and harness its power to its maximum potential. 

But many of the businesses are facing challenges in this transformative process because they are not aware of the technical backgrounds of AI and ML. Not only businesses, but even software engineers, are facing barriers due to a lack of knowledge of artificial intelligence.

In this blog post, you will also learn why open source AI libraries are important, how they differ from each other, and how AI libraries can address the pain points of businesses in the contemporary AI revolution.

So, without any further ado, let’s begin reading!

What is Open Source and its Key Principles?

Before we dive into the ocean of AI libraries, let’s clarify what “open source” means.

In the world of software development, “open source” refers to the process of making a source code of a project open for the public. In simple words, open source means a source where anyone can see the code of a project.

What is Open Source and its Key Principles? - PureLogics LLC

The purpose of this open source is to allow people to use it, modify it, and redistribute it to foster innovation and community-driven improvements.

So, it shows that the key principles of open source are: “transparency, accessibility, and the freedom to modify it and share the software.”

Importance of Open Source AI Libraries

The key principles of open-source libraries show that they offer hundreds of benefits. These libraries are open for community, and foster a supportive environment for community-driven software development. 

  • It’s a great source for both newbies and experienced developers alike.
  • It’s a great source for pre-built modules, algorithms, and tools. You now don’t need to reinvent the wheel for AI and ML development.
  • It’s a great place for the software development community.
  • It’s a great venue of innovation, creativity, and transparency.
