How It Works
Generative AI uses a computing process called deep learning to analyze patterns in large sets of data and replicate those patterns to create new data that mimics human-generated data. It employs neural networks, a type of machine learning process inspired by the way the human brain processes information.
The more data a generative AI model is trained on and generates, the more convincing and human-like its outputs become. This is because the machine learning algorithms powering generative AI models learn from the information they're fed.

Here's a breakdown of the key components involved in generative AI:
Generative AI models can be fine-tuned to gain more specific capabilities, such as creating content in a specific domain or style. This process is called fine-tuning, and it's a cost-effective way to adapt a model to a new task.
Under The Hood
Under the hood, generative AI uses deep learning to analyze patterns in large data sets and replicate those patterns to create new data that mimics human-generated data.
Generative AI employs neural networks, a type of machine learning process loosely inspired by the way the human brain processes, interprets, and learns from information over time.
To feed text into a generative AI model, it needs to be encoded into numbers, a process called tokenisation. For example, the sentence "this is a test" is encoded using a single token for each word.
This process is crucial because it allows the model to understand the relationships between various words in a sequence, giving a better understanding of overall context. This is made possible by the model's ability to use self-attention, a novel concept that allows it to learn the relationships between words.

The training datasets for LLMs aren't curated in any great detail, which means the models will have been exposed to content that results in undesirable output. To steer the model towards certain ethical principles, alignment is applied, which involves additional training to steer the model towards ethical principles.
Here are some key terms to understand:
- Token: a way to encode text into numbers to feed passages of text into the model
- Embeddings: a way to encode text as numbers that captures the semantics (meaning) of the text
- Attention: the model learns the relationships between various words in a sequence
- Alignment: additional training is applied to steer the model towards certain ethical principles
- Fine tuning: a technique where a model is trained on a generic dataset and then fine-tuned for a specific domain or dataset
Prompt Engineering
Prompt engineering is the art of crafting the perfect question to get the answer you need from a generative AI tool. It's about figuring out how to ask a question to get exactly the right output.
A strong prompt can make all the difference in the end user experience. The stronger, more relevant the prompt, the better the output will be.
You can use prompt engineering to ask a large language model to generate a personalized email to a customer. This can be a game-changer for customer service teams.
To get the most out of prompt engineering, it's essential to understand how to craft a strong prompt. This means carefully choosing the input that you give to the machine learning model.
Here are some key benefits of prompt engineering:
- Stronger, more relevant output
- Improved end user experience
- Ability to generate personalized content
- Ability to analyze customer feedback and extract key insights
Types of Generative AI
Generative adversarial networks (GANs) are a type of generative AI that works by training two neural networks on the same datasets to generate increasingly more realistic content over time.
These two networks, the generator and the discriminator, compete against each other, pushing each other to create better content. The generator creates data samples like images or text based on the training data, and the discriminator analyzes these samples to determine if they're real or generated.
In a GAN, the generator gets better at making images more realistic based on the feedback from the discriminator.

Traditional vs Non-Discriminative
Traditional AI is task-specific and rule-based, using predefined programming to perform specific tasks. It's designed to make predictions or rearrange information, but it doesn't generate new content.
Traditional AI can be seen in action in ticketing systems, where it identifies customer sentiment and intent to route requests to the right agent. This is a great example of how traditional AI can improve efficiency.
Generative AI, on the other hand, learns from large datasets to create human-like content. It identifies patterns and generates new data, making it perfect for creating unique and creative content.
Here's a quick comparison of traditional and generative AI:
Generative AI can also adapt to context and produce unique content, making it a powerful tool for businesses. By using both traditional and generative AI, businesses can analyze data and create new insights.
Discriminative vs Non-Discriminative
Discriminative AI specializes in classifying or categorizing data into predefined groups or classes. This type of AI learns to distinguish between different types of data, making it ideal for tasks requiring sorting data into categories.
It can identify whether an email is spam, recognize objects in an image, or diagnose diseases from medical scans by analyzing known data and classifying new data correctly.
Discriminative AI is used for analyzing and sorting data, whereas generative AI is designed to create original content or data. This makes each useful for different applications.

Adversarial Network
A Generative Adversarial Network (GAN) is made up of two neural networks: a generator and a discriminator. They compete with each other, with the generator creating an output based on some input, and the discriminator trying to determine if the output is real or fake.
The generator creates an output, such as an image or text, based on some input, while the discriminator evaluates the authenticity of the output. This cycle continues until the generator stumps the discriminator.
GANs allow for highly customized marketing that uses personalized images or text, like custom promotional imagery for every customer. They can also help development teams generate synthetic data when there is a lack of customer data, which is particularly useful when privacy concerns arise.
Here are some key benefits of GANs:
- Highly customized marketing
- Generation of synthetic data for development teams
Generative adversarial networks were first developed in 2024, and they work by training two different learning computers on the same datasets to generate increasingly more realistic content over time.
