1. Introduction

What is Generative AI?

In today’s digital era, generative AI refers to advanced artificial intelligence systems capable of producing diverse forms of content, including text, images, audio, video, and synthetic data. By 2025, it will have become a mainstream technology, powering applications from customer service and design to scientific research and drug discovery.
Although the concept dates back to the 1960s, recent breakthroughs in large language models, diffusion models, and multimodal transformers have vastly expanded its scope, enabling the creation of high-quality, human-like outputs in seconds and reshaping industries worldwide.

The Evolution of Generative AI

Generative AI has advanced significantly since its early experiments with chatbots in the 1960s. The breakthrough in 2014 with generative adversarial networks (GANs) enabled AI to produce convincingly authentic images, videos, and audio, making possible applications such as deepfakes, movie dubbing, and realistic synthetic data. Since then, diffusion models and hybrid approaches have emerged, joining GANs in raising the bar for realism and variety.
Another significant leap was the development of transformer architectures (since ~2017), which allow training on massive unlabeled datasets. By 2025, transformer-based models will be utilized not only for text but also for code generation, protein/DNA sequence modeling, multimodal tasks (combining image, text, and video), and more.
For example, a recent protein transformer model (SPT-Tiny) achieved 94.3% accuracy on one antibiotic resistance dataset and 99.6% on another (“Protein-FN”) by training from scratch.
Meanwhile, the GAN market (especially image-based) was valued at ~USD 5.52 billion in 2024, with forecasts projecting that it will reach an estimated $36.01 billion by 2030, reflecting a substantial CAGR of 37.7% from 2025 to 2030.

2. How Generative AI Works

The Process of Generative AI

Generative AI begins with a prompt—whether it’s text, an image, or another multimodal input. The system’s advanced algorithms then generate new content in response to these inputs. The journey from a user prompt to a final output is a sophisticated process that leverages several core components.

Inputs are first encoded into vectors, which are numerical representations of the data’s semantic meaning. Neural networks then utilize these vectors to generate new content that aligns with the prompt. While early models, such as GANs and VAEs, laid the groundwork, the field has undergone rapid evolution.

Today, the most prominent models follow a progression:

Agentic Models: Representing the latest evolution, agentic AI models are goal-driven systems that can autonomously plan and execute multi-step tasks. They don’t just generate content; they reason, interact with external tools, and even correct their own errors to achieve a specific objective with minimal human intervention.

Transformers: These architectures, with their “attention” mechanisms, have revolutionized AI by enabling models to track relationships across different parts of a sequence, whether it be words, pixels, or sounds. This made it possible to build and train much larger models on massive, unlabeled datasets, forming the backbone for the modern era of generative AI.

Large Language Models (LLMs): A direct descendant of the transformer architecture, LLMs are massive models trained on vast amounts of text data. They can perform a wide array of tasks, from generating coherent sentences and code to answering questions with remarkable accuracy.

Multimodal Models: These models go beyond a single data type, seamlessly integrating text, images, audio, and video. For example, a single model can now take a text prompt and a picture, then generate a new photo or a detailed description.

The Role of Vector Databases and RAG

To handle the massive scale and ensure accuracy, modern generative AI relies on two key technologies: vector databases and Retrieval Augmented Generation (RAG).

• Vector Databases: These are specialized databases that store data as vectors, enabling speedy and efficient “similarity searches.” This means the system can instantly find and retrieve information that is semantically similar to a user’s prompt, rather than relying on exact keyword matches. This is a foundational technology for grounding AI models.
• Retrieval Augmented Generation (RAG): This is a powerful technique that enhances an LLM’s output by retrieving relevant information from an external, authoritative knowledge base before generating a response. It prevents the model from “hallucinating” or providing outdated information by grounding its answers in specific, real-time data.
  The process works like this: when a user submits a query, the system first retrieves the most relevant documents from a vector database. It then provides both the original query and the retrieved documents to the LLM as context, instructing the model to generate a response based on this new information. This makes the generated output more accurate and verifiable, as it’s directly tied to a known source.

By 2025, transformers will underpin nearly 42% of the generative AI model market. The global generative AI market is expected to reach about US$70 billion this year, with spending projected to grow at ~40-44% CAGR through 2030. In software and IT sectors, 97% of workers are using transformer-based generative tools (mostly LLMs), with many reporting substantial productivity improvements. In India, GenAI is expected to increase productivity by 43-45% across IT services, with nearly 90% of firms trialing projects and about one-third already deploying them in production.
