Artificial Intelligence (AI) has swiftly transitioned from a futuristic idea to a crucial resource for businesses and developers. As AI becomes more ingrained in various sectors, the need for strong frameworks to build, test, and deploy AI models has surged. Whether you’re an experienced developer or just starting out, having the right tools can greatly streamline your work and accelerate your projects.
In this blog, we’ll review 15 free and affordable AI frameworks that offer high-quality features. These tools not only simplify the development process but also equip you with powerful resources for creating advanced AI models. Whether you’re looking for cost-effective options or the best value, this list has you covered.
Basic AI Frameworks: Easing Developers’ Lives
AI frameworks are important because they allow developers to access the nuts and bolts required for creating, training, and deploying machine learning models. These frameworks include built-in machine learning libraries, functions, and modules to decrease the time taken for the development of AI solutions from scratch. Developers can use these tools to let someone else do the grunt work while they focus on crafting a unique voice for their project — instead of concocting their own favorite password hashing scheme.
Why AI Frameworks Matter?
When creating and implementing artificial intelligence solutions, platforms carry the most weight. Read on to see four examples of why they’re so crucial:
- Faster Innovation: AI frameworks are a powerful tool that helps reduce the time needed to develop machine learning models. They have pre-built modules, which implies a developer does not need to work from scratch. This, in turn, speeds their innovation process and gives them the opportunity to concentrate on building new solutions or improving existing ones.
- Democratization of AI Development: Not all developers are AI or machine learning experts. AI frameworks provide high-level documentation and APIs that enable non-experts to perform AI experiments through a graphical interface. This democratization of AI developer labor means the field moves forward faster.
- Model Testing & Validation: AI frameworks generally provide tools for testing and validating models. These tools enable developers to test the accuracy and trustworthiness of their models before deployment. This is extremely important in critical systems such as healthcare or finance, where the inaccuracies of any AI model can have serious implications.
- Cost Reduction: AI model development is time-consuming and resource-extensive whilst training from scratch. AI frameworks are cost-effective ways to reuse components and algorithms. This brings down the cost of development, resulting in AI becoming readily available for businesses, big and small.
