What are Generative AI Models?
Generative AI models are a type of artificial intelligence that can create new images, text, audio, and more. Instead of just predicting things, they can generate brand-new creative outputs.
They learn patterns from huge amounts of data and use it to generate new things following the same patterns. Some good examples are text generators for writing, image creators, music makers, etc.
According to a survey from Gartner, businesses using Generative AI have helped them with a 15.8% revenue increase, 15.2% cost savings, and 22.6% improvement in productivity on average.
How Do Generative AI Models Work?
Generative AI models are data-driven models with the ability to create content. These models are trained using unsupervised or semi-supervised learning methods. Hence, Generative AI models can learn by studying large amounts of data from sources like the internet, Wikipedia, books, image collections, and more.
During this learning process, they can identify both the tiny details and the bigger patterns. This helps them to reconstruct those patterns when they generate new content, which will appear as though it is a human creation and not AI-generated.
Let us explore how Generative AI models are created using various methods and technologies.
Neural Networks
Neural network models are designed to operate similarly to the structure and function of a human brain. You can find nodes or neurons that are interconnected and arranged in layers. They give signals to each other.
Neural networks follow a process called backpropagation in which it learns by fine-tuning the weights and biases of these interconnected neurons.
Deep Learning
Deep learning is a sub-field of machine learning and uses neural networks that have several hidden layers. These are called deep neural networks. They help the models understand the complex patterns and relationships in data and replicate the human brain's decision-making abilities.
This technique is used to solve various issues like image, and speech recognition, and natural language processing.
Training Methods of Generative AI Models
Generative AI models are trained using various methods to make them more effective. Let us find out more below.
Unsupervised Learning
As the name suggests, the unsupervised learning method learns from data and does not require human intervention. It is also a type of machine learning method. It helps Generative AI models to self-train in unlabeled data and recognize the data structures, patterns, and relationships.
You can use this method for cases where labeled data is not available or is very little. It can work well in areas like customer segmentation, and image recognition.
Semi-Supervised Learning
Semi-supervised learning is a combination of supervised and unsupervised learning. It will contain both labeled and unlabeled training data with the labeled data available in a small portion. You can use this method in cases where it is difficult to access enough amount of labeled data, whereas unlabeled data is easily available.
With this labeled data, Generative AI models can understand initial patterns and use it to predict unlabeled data.
Generative AI vs LLM
When you learn about Generative AI models, it is inevitable to understand Large Language Models (LLMs) too. Both of these are related concepts, yet you can find notable differences when it comes to their focus, training data, and applications. Let us explore Generative AI vs LLM for these parameters.
| Parameter | LLMs | Generative AI |
| Focus | Their major focus is to understand and generate human language. They can process and analyze text data, making them appropriate for natural language processing (NLP) tasks. | Generative AI is more broader. It can generate content like text, image, music, codes, etc, and doesn't stop with language generation alone. |
| Training Data | They are trained on large text datasets from sources like the internet. They understand language patterns, grammar structure, and meaning from the data on which it is trained. | Based on their application, these models can be trained on various types of data. They learn to generate new content that resembles the existing patterns. |
| Applications | They are majorly used for tasks related to texts like translation, summarization, text completion, and sentiment analysis. | Generative AI uses are not limited to text. It is used for tasks like content creation, simulation, etc. |
Types of Generative AI Models
There are various types of Generative AI models and each has its own strengths and applications. Let us consider a few of these common types of models below.
Variational Autoencoders (VAEs)
VAEs are generative AI models that use unsupervised learning to encode and decode data. They consist of an encoder network that maps input data to a latent space and a decoder network that reconstructs the data from the latent space. They are widely used in tasks like image generation, image reconstruction, and data compression.
Generative Adversarial Networks (GANs)
GANs are Generative AI models that follow a game-theoretic approach. They consist of a generator network that produces synthetic data and a discriminator network that distinguishes between real and generated samples.
The two networks are trained adversarially, with the generator trying to generate realistic data to fool the discriminator. GANs have shown remarkable results in various domains, including image and video generation, transfer learning, and data augmentation.
Autoregressive Models
Autoregressive models are sequential Generative AI models that predict the probability distribution of the next element in a sequence, conditioned on the previous elements. They generate data by sampling from the predicted distribution and iteratively generating the next element of the sequence.
Autoregressive models are commonly used for tasks like text generation, speech synthesis, and time series prediction.
Flow-Based Models
Flow-based models are Generative AI models that transform complex data distributions into simple distributions. They use an invertible transformation to the input data and can reverse it easily. Initially, they start with a random noise and then use reverse transformation to quickly generate new samples which does not require complex optimization.
They can be used in domains like image generation, where they can generate high-quality images with controllable attributes.

Challenges in Generative AI models
Generative AI models, though quite helpful, also have their own limitations. These challenges are due to the complicated nature of the tasks that the model handles, ethical impacts, and others. Let us explore them below.
Training Instability
One of the primary challenges in the Generative AI use case is training instability. Generative models, such as GANs, often require a delicate balance between the generator and discriminator networks to converge to an optimal solution.
However, finding this balance can take time and effort, resulting in training instability. Training instability can lead to difficulties in achieving convergence, slow training progress, and mode collapse, where the generator produces limited and repetitive outputs.
Various techniques, such as adjusting learning rates, network architectures, and regularization methods, have been developed to address training instability in generative AI.
Mode Collapse
Mode collapse is a specific manifestation of training instability in generative AI models. It occurs when the generator of a GAN fails to explore the entire distribution of the training data and produces limited variations.
In other words, the generator collapses to generate a few representative samples, disregarding the full diversity of the target distribution. Mode collapse hampers the model's ability to generate diverse and novel samples.
Researchers have proposed several techniques, such as adding diversity-promoting objectives or regularization terms, to mitigate mode collapse and encourage the generation of a more diverse range of outputs.
Ethical Considerations
As Generative AI models become more powerful and capable, they raise important ethical considerations. One of the key concerns is the potential for misuse and the creation of deepfakes or fake content that can spread misinformation or be used for malicious purposes.
These AI-generated fakes have the potential to deceive individuals and undermine trust.
