Artificial intelligence focuses on building machines capable of performing tasks that are typically thought to require human intelligence.
Artificial intelligence (AI) is a branch of computer science that aims to build machines capable of performing tasks that typically require human intelligence. AI enables machines to simulate human abilities, such as learning, problem-solving, decision-making and comprehension. Common applications of AI include speech recognition, image recognition, content generation, recommendation systems, self-driving cars and AI agents.
Artificial intelligence (AI) is technology that allows machines to simulate human intelligence and cognitive capabilities. AI can be used to help make decisions, solve problems and perform tasks that are normally accomplished by humans.
While AI is an interdisciplinary science with multiple approaches, advancements in machine learning and deep learning in particular are changing virtually every industry, making AI an increasingly integral part of everyday life.
Artificial intelligence refers to computer systems that are capable of performing tasks traditionally associated with human intelligence — such as making predictions, identifying objects, interpreting speech and generating natural language. AI systems learn how to do so by processing massive amounts of data and looking for patterns to model in their own decision-making. In many cases, humans will supervise an AI’s learning process, reinforcing good decisions and discouraging bad ones, but some AI systems are designed to learn without supervision.
Over time, AI systems improve on their performance of specific tasks, allowing them to adapt to new inputs and make decisions without being explicitly programmed to do so. In essence, artificial intelligence is about teaching machines to think and learn like humans, with the goal of automating work and solving problems more efficiently.
Artificial intelligence aims to provide machines with similar processing and analysis capabilities as humans, making AI a useful counterpart to people in everyday life. AI is able to interpret and sort data at scale, solve complicated problems and automate various tasks simultaneously, which can save time and fill in operational gaps missed by humans.
AI serves as the foundation for computer learning and is used in almost every industry — from healthcare and finance to manufacturing and education — helping to make data-driven decisions and carry out repetitive or computationally intensive tasks.
Many existing technologies use artificial intelligence to enhance capabilities. We see it in smartphones with AI assistants, e-commerce platforms with recommendation systems and vehicles with autonomous driving abilities. AI also helps protect people by piloting fraud detection systems online and robots for dangerous jobs, as well as leading research in healthcare and climate initiatives.
“AI is the new electricity,” according to Andrew Ng, co-founder of Google Brain and a leader in the AI industry.
Artificial intelligence systems work by using algorithms and data. First, a massive amount of data is collected and applied to mathematical models, or algorithms, which use the information to recognize patterns and make predictions in a process known as training. Once algorithms have been trained, they are deployed within various applications, where they continuously learn from and adapt to new data. This allows AI systems to perform complex tasks like image recognition, language processing and data analysis with greater accuracy and efficiency over time.
Artificial intelligence is composed of several specialized subfields, each focused on solving unique problems and advancing specific aspects of AI behavior. The main subfields of AI include:
The primary approach to building AI systems is through machine learning (ML), where computers learn from large data sets by identifying patterns and relationships within the data. A machine learning algorithm uses statistical techniques to help it “learn” how to get progressively better at a task, without necessarily having been programmed for that certain task. It uses historical data as input to predict new output values.
Machine learning consists of different types of learning methods:
Machine learning is typically done using neural networks, a series of algorithms that process data by mimicking the structure of the human brain. These networks consist of layers of interconnected nodes, or “neurons,” that process information and pass it between each other. By adjusting the strength of connections between these neurons, the network can learn to recognize complex patterns within data, make predictions based on new inputs and even learn from mistakes. This makes neural networks useful for recognizing images, understanding human speech and translating words between languages.
Deep learning is an important subset of machine learning. It uses a type of artificial neural network known as deep neural networks, which contain a number of hidden layers through which data is processed, allowing a machine to go “deep” in its learning and recognize increasingly complex patterns, making connections and weighting input for the best results. Deep learning is particularly effective at tasks like image and speech recognition and natural language processing, making it a crucial component in the development and advancement of AI systems.
Natural language processing (NLP) involves teaching computers to understand and produce written and spoken language in a similar manner as humans. NLP combines computer science, linguistics, machine learning and deep learning concepts to help computers analyze unstructured text or voice data and extract relevant information from it. NLP mainly tackles speech recognition and natural language generation, and it’s leveraged for use cases like spam detection and virtual assistants.
Computer vision is another prevalent application of deep learning techniques, where machines process raw images, videos and visual media, and extract useful insights from them. Deep learning and convolutional neural networks are used to break down images into pixels and tag them accordingly, which helps computers discern the difference between visual shapes and patterns. Computer vision is used for image recognition, image classification and object detection, and completes tasks like facial recognition and detection in self-driving cars and robotics.
Generative AI is a subfield of artificial intelligence focused on creating new content — such as text, images, videos and more — that mimics human creativity based on user prompts. Using deep learning technologies like large language models (LLMs) and generative adversarial networks (GANs), generative AI learns patterns from large data sets to output content that is highly similar to its original training data.
Generative AI has applications across industries like art, entertainment, marketing and software development, and is redefining how humans and machines collaborate in the creative process.
AI agents are AI systems designed to autonomously perceive their environment, make decisions and take actions to accomplish specific tasks.
Agentic AI refers to a system of multiple AI agents that combine reasoning and memory over time. This enables an agentic AI system to perform complex, multi-step tasks that a single agent couldn’t accomplish on its own, such as conducting research or troubleshooting software without constant human intervention.
The capabilities of AI agents and agentic AI are powered by deep learning models, which allow these systems to understand language, interpret data and predict outcomes based on patterns learned from large data sets.
Generative AI has gained massive popularity in the 2020s, especially as chatbots and image generators get increasingly more sophisticated. These tools are often used to create written copy, code, digital art and object designs, and they are leveraged in industries like marketing, entertainment, consumer goods and manufacturing.
Generative AI also comes with challenges, though. For instance, it can be used to create harmful content and deepfakes, which could spread disinformation and erode social trust. And some AI-generated material could potentially infringe on people’s copyright and intellectual property rights.
To work, a generative AI model is fed massive data sets and trained to identify patterns within them, then subsequently generates outputs that resemble this training data. Here’s a breakdown of each step:
The basis of generative AI models are foundation models, which are large-scale AI systems trained on massive amounts of data to develop a broad understanding of language, images, code and related content. In the generative AI training phase, a foundation model is fed large data sets from the internet, books and literature in order to learn and understand patterns and relationships within this data.
Over time, the model learns to generate outputs that resemble the training data, though it does not memorize it directly.
After general training, generative AI models are often fine-tuned for more specific applications, whether that be to generate images, text or other specific media. Fine-tuning involves retraining the model on a smaller, application-specific data set, such as technical documents or legal texts. This helps the model become more accurate and relevant within its particular context.
In some cases, reinforcement learning from human feedback (RLHF) is also used to guide the model toward preferred outputs and reduce hallucinations.
Once trained and initially tuned, the generative AI model can generate content based on user prompts. The way it generates content relies on probabilistic predictions to create outputs that are contextually appropriate and align with the given inputs.
At this stage, the model tends to be evaluated using automated metrics and human judgement in order to assess factual accuracy, quality and alignment with user intent.
Depending on regular model assessments, a generative AI model can also be further tuned for greater relevance and accuracy.
Artificial intelligence can be classified in several different ways.
AI can be organized into two broad categories: weak AI and strong AI.
AI can then be further categorized into four main types: reactive machines, limited memory, theory of mind and self-awareness.
AI is beneficial for automating repetitive tasks, solving complex problems, reducing human error and much more.
Repetitive tasks such as data entry and factory work, as well as customer service conversations, can all be automated using AI technology. This lets humans focus on other priorities.
AI’s ability to process large amounts of data at once allows it to quickly find patterns and solve complex problems that may be too difficult for humans, such as predicting financial outlooks or optimizing energy solutions.
AI can be applied through user personalization, chatbots and automated self-service technologies, making the customer experience more seamless and increasing customer retention for businesses.
AI works to advance healthcare by accelerating medical diagnoses, drug discovery and development and medical robot implementation throughout hospitals and care centers.
The ability to quickly identify relationships in data makes AI effective for catching mistakes or anomalies among mounds of digital information, overall reducing human error and ensuring accuracy.
While artificial intelligence has its benefits, the technology also comes with several risks and potential dangers to consider.
AI’s abilities to automate processes, generate rapid content and work for long periods of time can mean job displacement for human workers.
AI models may be trained on data that reflects biased human decisions, leading to outputs that are biased or discriminatory against certain demographics.
AI systems may inadvertently “hallucinate” or produce inaccurate outputs when trained on insufficient or biased data, leading to the generation of false information.
The data collected and stored by AI systems may be done so without user consent or knowledge, and may even be accessed by unauthorized individuals in the case of a data breach.
AI systems may be developed in a manner that isn’t transparent or inclusive, resulting in a lack of explanation for potentially harmful AI decisions as well as a negative impact on users and businesses.
Large-scale AI systems can require a substantial amount of energy to operate and process data, which increases carbon emissions and water consumption.
Specific use cases and examples of AI include:
Generative AI tools — including ChatGPT, Gemini, Claude and Grok — use artificial intelligence to produce written content in a range of formats, from essays to code and answers to simple questions.
Personal AI assistants, like Alexa and Siri, use natural language processing to receive instructions from users to perform a variety of “smart tasks.” They can carry out commands like setting reminders, searching for online information or turning off your kitchen lights.
Self-driving cars are a recognizable example of deep learning, since they use deep neural networks to detect objects around them, determine their distance from other cars, identify traffic signals and much more.
Many wearable sensors and devices used in the healthcare industry apply deep learning to assess the health condition of patients, including their blood sugar levels, blood pressure and heart rate. They can also derive patterns from a patient’s prior medical data and use that to anticipate any future health conditions.
Filters used on social media platforms like TikTok and Snapchat rely on algorithms to distinguish between an image’s subject and the background, track facial movements and adjust the image on the screen based on what the user is doing.
Artificial intelligence has applications across multiple industries, ultimately helping to streamline processes and boost business efficiency.
AI is used in healthcare to improve the accuracy of medical diagnoses, facilitate drug research and development, manage sensitive healthcare data and automate online patient experiences. It is also a driving factor behind medical robots, which work to provide assisted therapy or guide surgeons during surgical procedures.
AI in retail amplifies the customer experience by powering user personalization, product recommendations, shopping assistants and facial recognition for payments. For retailers and suppliers, AI helps automate retail marketing, identify counterfeit products on marketplaces, manage product inventories and pull online data to identify product trends.
In the customer service industry, AI enables faster and more personalized support. AI-powered chatbots and virtual assistants can handle routine customer inquiries, provide product recommendations and troubleshoot common issues in real-time. And through NLP, AI systems can understand and respond to customer inquiries in a more human-like way, improving overall satisfaction and reducing response times.
AI in manufacturing can reduce assembly errors and production times while increasing worker safety. Factory floors may be monitored by AI systems to help identify incidents, track quality control and predict potential equipment failure. AI also drives factory and warehouse robots, which can automate manufacturing workflows and handle dangerous tasks.
The finance industry utilizes AI to detect fraud in banking activities, assess financial credit standings, predict financial risk for businesses plus manage stock and bond trading based on market patterns. AI is also implemented across fintech and banking apps, working to personalize banking and provide 24/7 customer service support.
In the marketing industry, AI plays a crucial role in enhancing customer engagement and driving more targeted advertising campaigns. Advanced data analytics allows marketers to gain deeper insights into customer behavior, preferences and trends, while AI content generators help them create more personalized content and recommendations at scale. AI can also be used to automate repetitive tasks such as email marketing and social media management.
Video game developers apply AI to make gaming experiences more immersive. Non-playable characters (NPCs) in video games use AI to respond accordingly to player interactions and the surrounding environment, creating game scenarios that can be more realistic, enjoyable and unique to each player.
AI assists militaries on and off the battlefield, whether it’s to help process military intelligence data faster, detect cyberwarfare attacks or automate military weaponry, defense systems and vehicles. Drones and robots in particular may be imbued with AI, making them applicable for autonomous combat or search and rescue operations.
As AI grows more complex and powerful, lawmakers around the world are seeking to regulate its use and development.
The first major step to regulate AI occurred in 2024 in the European Union with the passing of its sweeping Artificial Intelligence Act, which aims to ensure that AI systems deployed there are “safe, transparent, traceable, non-discriminatory and environmentally friendly.” Countries like China and Brazil have also taken steps to govern artificial intelligence.
Meanwhile, AI regulation in the United States is still a work in progress. The Biden-Harris administration introduced a non-enforceable AI Bill of Rights in 2022, and then The Executive Order on Safe, Secure and Trustworthy Development and Use of Artificial Intelligence in 2023, which aimed to regulate the AI industry while maintaining the country’s status as a leader in the industry. However, The Executive Order on Safe, Secure and Trustworthy Development and Use of Artificial Intelligence was revoked by President Donald Trump in January 2025.
The U.S. Congress has also made several attempts to establish more robust legislation, but it has largely failed, leaving no laws in place that specifically limit the use of AI or regulate its risks. For now, all AI legislation in the United States exists only on the state level.
With that said, in May 2025, President Trump’s “One, Big, Beautiful Bill” Act — which proposes a 10-year ban on all U.S. state regulations of artificial intelligence — passed the U.S. House of Representatives, leaving the future of U.S. AI regulation to be uncertain.
Though as stated by Microsoft CEO Satya Nadella, “[AI] regulation that allows us to ensure that the broad societal benefits are amplified, and the unintended consequences are dampened, is going to be the way forward.”
The future of artificial intelligence holds immense promise, with the potential to revolutionize industries, enhance human capabilities and solve complex challenges. It can be used to develop new drugs, optimize global supply chains and power advanced robots — transforming the way we live and work.
Looking ahead, one of the next big steps for artificial intelligence is to progress beyond weak or narrow AI and achieve artificial general intelligence (AGI) — and eventually superintelligence. With AGI, machines will be able to think, learn and act the same way as humans do, blurring the line between organic and machine intelligence. This could pave the way for increased automation and problem-solving capabilities in medicine, manufacturing, transportation and more — as well as sentient AI down the line.
In a 2024 essay about the promises of the technology, Anthropic CEO Dario Amodei speculates that powerful AI might accelerate innovation in the biological sciences as much as tenfold by enabling a larger number of experiments to be conducted at any given time, and by shortening the gap between new discoveries and subsequent research building on those discoveries.
On the other hand, the increasing sophistication of AI also raises concerns about heightened job loss, widespread disinformation and loss of privacy. And questions persist about the potential for AI to outpace human understanding and intelligence — a phenomenon known as technological singularity that could lead to unforeseeable risks and possible moral dilemmas.
For now, society is largely looking toward government and business-level AI regulations to help guide the technology’s future.
Artificial intelligence as a concept began to take off in the 1950s when computer scientist Alan Turing released the 1950 paper “Computing Machinery and Intelligence,” which questioned if machines could think and how one would test a machine’s intelligence. This paper set the stage for AI research and development, and was the first proposal of the Turing test, a method used to assess machine intelligence. The term “artificial intelligence” was coined in 1956 by computer scientists John McCarthy, Marvin Minsky, Nathaniel Rochester and Claude E. Shannon at a Dartmouth College academic conference.
Following the Dartmouth College conference and throughout the 1970s, interest in AI research grew from academic institutions and U.S. government funding. Innovations in computing allowed several AI foundations to be established during this time, including machine learning, neural networks and natural language processing.
Despite its advances, AI technologies eventually became more difficult to scale than expected and declined in interest and funding, resulting in the first AI winter until the 1980s.
In the mid-1980s, AI interest reawakened as computers became more powerful, deep learning became popularized and AI-powered “expert systems” were introduced. However, due to the complication of new systems and an inability of existing technologies to keep up, the second AI winter occurred and lasted until the mid-1990s.
By the mid-2000s, innovations in processing power, big data and advanced deep learning techniques resolved AI’s previous roadblocks, allowing further AI breakthroughs. Modern AI technologies like virtual assistants, driverless cars and generative AI began entering the mainstream in the 2010s, making AI what it is today.
John McCarthy and Alan Turing are widely considered to be the founders of artificial intelligence. Turing introduced the concept of AI and the Turing test in his 1950 paper “Computing Machinery and Intelligence,” where he explored the possibility of machines exhibiting human-like intelligence and proposed a method to evaluate these abilities. McCarthy helped coined the term “artificial intelligence” in 1956 and conducted foundational research in the field.
The concept of artificial intelligence began in 1950 with Alan Turing’s paper, “Computing Machinery and Intelligence.” The term “artificial intelligence” was coined in 1956 by John McCarthy.
AI works to simulate human intelligence by using algorithms to analyze large amounts of data, identify data patterns and make decisions based on those patterns. By training on specific data, AI systems “learn” to identify relationships within the data, and can adapt as they are exposed to new information over time.
AI is being used to power virtual assistants, personalized content and product recommendations, image generators, chatbots, self-driving cars, facial recognition systems and more.
The 7 main types of artificial intelligence are:
Generative AI refers to an artificial intelligence system that can create new content (like text, images, audio or video) based on user prompts. Generative AI is the backbone of popular chatbots like ChatGPT, Gemini and Claude, and can be used to instantly create written copy, reports, code, digital images, music and other media.
