AI Development Tools and Frameworks You Need to Know

AI frameworks and tools are the backbone of AI models. They help them learn, adapt, and evolve. These frameworks allow AI development companies to create sophisticated AI software to enhance business operations and go beyond and above human capabilities. They are a collection of libraries to develop and implement AI algorithms. There are two types of AI frameworks:

• Open-source AI frameworks
• Proprietary AI frameworks

Open-source AI Frameworks:

As the name suggests, open-source AI frameworks are free software for the public to use. Any developer from any part of the world has access to source code, model architecture, and training datasets. As a result, developers access a collaborative environment to build new AI models, share ideas, and take innovations to a whole new level. Examples: TensorFlow, PyTorch, Scikit-learn, Hugging Face, OpenCV, etc.

Proprietary AI Frameworks:

The proprietary AI frameworks, however, require commercial licenses. Developers and businesses need to purchase the license to use them due to their restricted access. These frameworks provide excellent performance, unique capabilities, and advanced functionalities with limited customization abilities, making them best suitable for large-scale projects. Examples: IBM Watson, Microsoft CNTK, Microsoft Azure AI, etc.

The right AI framework can effectively ease the AI model development. Look at the following key factors to consider before selecting the framework and starting your next AI app development.

Project Requirements

What is your project goal? Do you wish to develop a chatbot? Are you planning to develop an image generation tool or something else? Will your AI model be multi-functional? Answer these questions, and you will know which tool is the best for your project. For example, TensorFlow provides ease of customization, and Scikit-learn offers simplicity, saving developers’ time and effort. However, if your project goal is to provide high performance, select a proprietary AI framework. You can also discuss your project with your AI development company and get the best guidance from industry experts.

Performance

If high performance is the requirement, proprietary AI frameworks trump open-source. However, for proprietary AI frameworks, AI development companies need to invest heavily to gain licenses and access to advanced functions. Meanwhile, the open-source AI frameworks are free and offer vast community support, flexibility, transparency, and scalability with optimal performance. For example, Stable Diffusion is a generative AI model developed by Stability AI for video and animation generation. It is a high-performing AI model developed using an open-source AI framework.

Complexity

Some AI frameworks—both open and proprietary—are simple to learn, while others require considerable time to master. Some AI frameworks provide excellent flexibility with other technologies and can handle complex computing. It also depends on the project complexity and other algorithms used. For example, the LiteRT or TensorFlow Lite library is an excellent choice for deploying machine learning models on mobile devices.

Scalability

With the rise of web and mobile software development, scalability can become an issue in the future if not considered. A right AI framework with excellent community support, robust API support, excellent cross-platform compatibility, etc., can help upscale the project’s capabilities in the future. For example, Apache Mahout and Microsoft CNTK are two of the most preferred AI frameworks to choose for scalability, data processing, and accuracy.

Existing Tech Stack

You must also consider which AI frameworks work best with the existing tech stack for AI model development. Nowadays, most AI development companies opt for a framework that works on both CPU and GPU. These factors can help you choose the right AI framework and leave no room for any confusion. You can also discuss with your web and mobile app development agency for the best guidance in the field. Now, we will discuss the top 10 AI development tools you must watch out for in 2025.
