How does generative AI work?
Generative AI begins with a prompt, which can take the form of text, images, videos, designs, musical notes, or any input that the AI system can interpret. Different AI algorithms then generate new content in reaction to the prompt. This content can range from essays and problem solutions to realistic creations made from images or audio of a person.
Early versions of generative AI required submitting data via an API or an otherwise complicated process. Developers had to familiarize themselves with special tools & write applications using languages such as Python.
Currently, innovators in generative AI are working on enhancing user experiences by allowing them to communicate their requests in natural language. Following an initial response, users can further personalize the outcomes by providing feedback on the desired style, tone, and other specific elements they want the generated content to embody.
Generative AI models
Generative AI models use various algorithms to represent & process content, such as natural language processing for text & transforming images into visual elements. However, these techniques can also encode biases & deception from the training data.
Neural networks like GANs & VAEs are used to generate new content, including realistic human faces & synthetic data. Recent progress in transformers like BERT, GPT, & AlphaFold have resulted in neural networks that can encode & generate new content for language, images, & proteins.

Types of Generative Models
There are various types of generative models, each with its own unique approach to understanding & creating data. Here’s a more comprehensive list of some of the most prominent types:
- Bayesian networks. These are graphical models that represent the probabilistic relationships among a set of variables. They’re particularly useful in scenarios where understanding causal relationships is crucial. For example, in medical diagnosis, a Bayesian network might help determine the likelihood of a disease given a set of symptoms.
- Diffusion models. These models describe how things spread or change over time. They’re often used in scenarios like understanding how a rumor spreads in a network or predicting the spread of a virus in a population.
- Generative Adversarial Networks (GANs). GANs consist of two neural networks, the generator & the discriminator, that are trained together. The generator tries to produce data, while the discriminator attempts to distinguish between real & generated data. Over time, the generator becomes so good that the discriminator can’t tell the difference. GANs are popular in image generation tasks, such as creating realistic human faces or artworks.
- Variational Autoencoders (VAEs). VAEs are a type of autoencoder that produces a compressed representation of input data, then decodes it to generate new data. They’re often used in tasks like image denoising or generating new images that share characteristics with the input data.
- Restricted Boltzmann Machines (RBMs). RBMs are neural networks with two layers that can learn a probability distribution over its set of inputs. They’ve been used in recommendation systems, like suggesting movies on streaming platforms based on user preferences.
- Pixel Recurrent Neural Networks (PixelRNNs). These models generate images pixel by pixel, using the context of previous pixels to predict the next one. They’re particularly useful in tasks where the sequential generation of data is crucial, like image generation.
What are the limitations of generative AI?
Early versions of generative AI demonstrate numerous limitations. Some of the difficulties associated with generative AI arise from the specific methods used to implement certain use cases. For instance, a concise summary of a complex topic may be more accessible than an explanation that incorporates multiple supporting sources.
However, the readability of the summary may come at the cost of transparency regarding the information’s origins. Here are several limitations to consider when developing or utilizing a generative AI application:
– It may not consistently attribute the source of content.
– Assessing the bias of original sources can be challenging.
– Realistic-sounding content can obscure inaccurate information.
– Understanding how to adapt for new circumstances can be difficult.
– Results may overlook bias, prejudice, & animosity.
What are the concerns surrounding generative AI?
The emergence of generative AI is raising various concerns, including the quality of outcomes, potential for misuse & abuse, & the possibility of disrupting existing business models. Some specific problematic issues resulting from current generative AI capabilities include:
– The potential for providing inaccurate & deceptive information.
– Difficulty in trusting information without knowledge of its source & origin.
– The promotion of new forms of plagiarism that disregard the rights of original content creators & artists.
– Disruption of established business models centered around search engine optimization & advertising.
– The facilitation of generating fake news.
– The ease of claiming that authentic photographic evidence of wrongdoing is merely an AI-generated fake.
– The potential for impersonating individuals to conduct more effective social engineering cyber attacks.
