By now, you’ve heard of generative artificial intelligence (AI) tools like ChatGPT, DALL-E, and GitHub Copilot, among others. They’re gaining widespread interest thanks to the fact that they allow anyone to create content from email subject lines to code functions to artwork in a matter of moments.
This potential to revolutionize content creation across various industries makes it important to understand what generative AI is, how it’s being used, and who it’s being used by. In this article, we’ll explore what generative AI is, how it works, some real-world applications, and how it’s already changing the way people (and developers) work.
You may have heard the buzz around new generative AI tools like ChatGPT or the new Bing, but there’s a lot more to generative AI than any one single framework, project, or application.
Traditional AI systems are trained on large amounts of data to identify patterns, and they’re capable of performing specific tasks that can help people and organizations. But generative AI goes one step further by using complex systems and models to generate new, or novel, outputs in the form of an image, text, or audio based on natural language prompts.
Generative AI models and applications can, for example, be used for:
Data generation. Creating new data—which is called synthetic data—and augmenting existing data sets is another common use case for generative AI. This involves generating new samples from an existing dataset to increase the dataset’s size and improve machine learning models trained on it, all while providing a layer of privacy since real user data is not being utilized to power models. Synthetic data generation provides a way to create useful, meaningful data for more than just ML training though—a number of self-driving car companies like Cruise and Waymo utilize AI-generated synthetic data for training perception systems to prepare vehicles for real-world situations while in operation.
Language translation. Natural-language understanding (NLU) models combined with generative AI have become increasingly popular to provide language translations on-the-fly. These types of tools help companies break language barriers and increase their scope of accessibility for customer bases by being able to provide things like support or documentation in their native language. Through complex, deep learning algorithms, generative AI is able to understand the context of a source text and linguistically construct those sentences in another language. This practice can also apply to coding languages, for example, translating a desired function from Python to Java.
The bottom line: Even though generative AI is a relatively new technology, it’s already being used in consumer and business applications. The use cases, as well as the quantity of applications created with it, will continue evolving to meet more distinct and specific needs.
Generative AI models work by using neural networks to identify patterns from large sets of data, then generate new and original data or content.
But what are neural networks? In simple terms, they use interconnected nodes that are inspired by neurons in the human brain. These networks are the foundation of machine learning and deep learning models, which use a complex structure of algorithms to process large amounts of data such as text, code, or images. Training these neural networks involves adjusting the weights or parameters of the connections between neurons to minimize the difference between predicted and desired outputs, which allows the network to learn from mistakes and make more accurate predictions based on the data.
Algorithms are a key component of machine learning and generative AI models. But beyond helping machines learn from data, algorithms are also used to optimize accuracy of outputs and make decisions, or recommendations, based on input data.
While algorithms help automate these processes, building a generative AI model is incredibly complex due to the massive amounts of data and compute resources they require. People and organizations need large datasets to train these models, and generating high-quality data can be time-consuming and expensive.
To restate the obvious, these models are complicated. Need proof? Here are some common generative AI models and how they work:
Generative adversarial networks (GAN): GANs are one of the most used models for generative AI, and they employ two different neural networks. GANs consist of two different types of neural networks: a generator and a discriminator. The generator network generates new data, such as images or audio, from a random noise signal while the discriminator is trained to distinguish between real data from the training set and the data produced by the generator.
During training, the generator tries to create data that can trick the discriminator network into thinking it’s real. This “adversarial” process will continue until the generator can produce data that is totally indistinguishable from real data in the training set. This process helps both networks improve at their respective tasks, which ultimately results in more realistic and higher-quality generated data.
The impact of generative AI is quickly becoming apparent—but it’s still in its early days. Despite this, we’re already seeing a proliferation of applications, products, and open source projects that are using generative AI models to achieve specific outcomes for people and organizations (and yes, developers, too).
Though generative AI is constantly evolving, it already has some solid real world applications. Here’s just a few of them:
New and seasoned developers alike can utilize generative AI to improve their coding processes. Generative AI coding tools can help automate some of the more repetitive tasks, like testing, as well as complete code or even generate brand new code. GitHub has its own AI-powered pair programmer, GitHub Copilot, which uses generative AI to provide developers with code suggestions. And GitHub also has announced GitHub Copilot X, which brings generative AI to more of the developer experience across the editor, pull requests, documentation, CLI, and more.
Generative AI has the potential to greatly impact and improve accessibility for folks with disabilities through a variety of modalities, such as speech-to-text transcription, text-to-speech audio generation, or assistive technologies. One of the most exciting facets of our GitHub Copilot tool is its voice-activated capabilities that allow developers with difficulties using a keyboard to code with their voice. By leveraging the power of generative AI, these types of tools are paving the way for a more inclusive and accessible future in technology.
Generative AI can take gaming to the next level (get it? 😉) by generating new characters, storylines, design components, and more. Case in point: The developer behind the game, This Girl Does Not Exist, has said that every component of the game—from the storyline to the art and even the music—was generated entirely by AI. This use of generative AI can enable gaming studios to create new and exciting content for their users, all without increasing the developer workload, which frees them up to work on other aspects of the game, such as story development.
Designers can utilize generative AI tools to automate the design process and save significant time and resources, which allows for a more streamlined and efficient workflow. Additionally, incorporating these tools into the development process can lead to the creation of highly customized designs and logos, enhancing the overall user experience and engagement with the website or application. Generative AI tools can also be used to do some of the more tedious work, such as creating design layouts that are optimized and adaptable across devices. For example, designers can use tools like designs.ai to quickly generate logos, banners, or mockups for their websites.
Microsoft and other industry players are increasingly utilizing generative AI models in search to create more personalized experiences. This includes query expansion, which generates relevant keywords to reduce the number of searches. So, rather than the search engine returning a list of links, generative AI can help these new and improved models return search results in the form of natural language responses. Bing now includes AI-powered features in partnership with OpenAI that provide answers to complex questions and allow users to ask follow-up questions in a chatbox for more refined responses.
Interest has emerged around the potential applications of generative AI in the healthcare field to improve disease detection and diagnosis, advance medical research, and accelerate progress in the pharmaceutical space. Potentially, generative AI could be used to analyze large amounts of data to simulate chemical structures and predict new compounds will be the most effective for new drug discoveries. NVIDIA Clara is one example of a generative AI model specifically designed for medical imaging and healthcare research. (Plus, Gartner suggests more than 30 percent of new pharmaceutical drugs and materials will be discovered via generative AI models by 2025.)
Fun fact: Did you know that ChatGPT recently passed the US Medical Licensing exam without any intervention from clinicians?
In marketing, content is king—and generative AI is making it easier than ever to quickly create large amounts of it. A number of companies, agencies, and creators are already turning to generative AI tools to create images for social posts or write captions, product descriptions, blog posts, email subject lines, and more. Generative AI can also help companies personalize ad experiences by creating custom, engaging content for individuals at speed. Writers, marketers, and creators can leverage tools like Jasper to generate copy, Surfer SEO to optimize organic search, or albert.ai to personalize digital advertising content.
As we’ve seen above, the power of AI can be harnessed to create some incredible portraits in a matter of moments (re: the future-telling Shiba 🐕). Artists and designers alike are using these AI tools as a source of inspiration. For example, architects can quickly create 3D models of objects or environments and artists can breathe new life into their portraits by using AI to apply different styles, like adding a Cubist style to their original image. Need proof? Designers are already starting to use AI image generators, such as Midjourney and Microsoft Designer, to create high-quality images by simply typing out Discord commands.
In a recent discussion about tech trends and how they’ll affect the finance sector, Michael Schrage, a research fellow at the MIT Sloan School Initiative on the Digital Economy, said, “I think, increasingly, we’re going to be seeing generative AI used for financial forecasts and scenario generation.” This is a likely path forward—generative AI can be used to analyze large amounts of data to detect fraud, manage risk, and inform decision making. And that has obvious applications in the financial services industry.
Manufacturers are starting to turn to generative AI solutions to help with product design, quality control, and predictive maintenance. Generative AI can be used to analyze historical data to improve machine failure predictions and help manufacturers with maintenance planning. According to research conducted by Capgemini, more than half of European manufacturers are implementing some AI solutions (although so far, these aren’t generative AI solutions). This is largely because the sheer amount of manufacturing data is easier for machines to analyze at speed than humans.
AI as a partner: Generative AI models and tools are narrow in focus, and work best at generating content, code, and images. In research at GitHub, we’ve found that GitHub Copilot helps developers code up to 55% faster, underscoring how generative AI models and tools can improve overall productivity and boost efficiency. Metrics like these show how generative AI tools are already changing how people and teams work—but they also underscore how these tools act as complement to human efforts.
Whether it’s creating visual assets for an ad campaign or augmenting medical images to help diagnose diseases, generative AI is helping us solve complex problems at speed. And the emergence of generative AI-based programming tools has revolutionized the way developers approach writing code.
We know that developers want to design and write software quickly, and tools like GitHub Copilot are enabling them to access large datasets to write more efficient code and boost productivity. In fact, 96% of developers surveyed reported spending less time on repetitive tasks using GitHub Copilot, which in turn allowed 74% of them to focus on more rewarding work.
While these models aren’t perfect yet, they’re getting better by the day—and that’s creating an exciting immediate future for developers and generative AI.
