Generative AI has become one of the most impactful technologies in artificial intelligence since its public launch in late 2022, driving innovation across industries. Cloud platforms like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud provide a variety of tools and services to make generative AI accessible to everyone. Large Language Models (LLMs), which are central to Generative AI, can generate human-like text, write code, create images, and perform various other tasks.
In this article, we will take a high-level look at the various generative AI solutions offered by these three cloud platforms. Detailed articles about generative AI in each of these platforms would follow later. We will also discuss the LLMs each platform supports, their features, use case fitment, integration capabilities, pricing, and security considerations. This article assumes that you’re familiar with generative AI and it terminologies.

Generative AI vs Traditional AI
Generative AI differs from traditional AI primarily in its focus on creating new content, such as text, images, and code, by learning patterns from vast datasets. It uses models like Generative Pre-trained Transformer (GPT) and Generative Adversarial Networks (GANs), allowing for creative tasks like text generation or image creation. Traditional AI, on the other hand, focuses on specific tasks like classification, prediction, and decision-making, using supervised learning and models like decision trees or neural networks. While generative AI excels at open-ended and creative tasks, traditional AI is more analytical and used for optimization, prediction, and automation.
