The Evolution of Generative AI – From Eliza to GPT-4

Today in this article I will explore the fascinating evolution of Generative AI, from its early roots in rule-based systems to the current era of sophisticated deep learning models. We will trace key milestones and technologies, highlighting how AI has progressed from rigid, pre-programmed responses to generating remarkably creative and realistic content like text, images, and music.

We will also delve into the limitations of early approaches and the breakthroughs enabled by deep learning models such as VAEs, GANs, and Transformers. Finally, we will touch upon emerging trends and the ethical considerations surrounding this rapidly advancing field. The journey of Generative AI showcases not only technological progress but also the expanding horizon of what AI can achieve, offering a glimpse into a future where machines actively participate in the creative process.
