In 2012, a neural network built by Google engineers taught itself to recognize cats in YouTube videos — without anyone telling it what a cat looked like. That experiment, run on 16,000 computer processors, felt like a quirky lab stunt at the time. Fourteen years later, AI software powers the drugs your doctor prescribes, the prices airlines charge you, the code your developers ship, and the ads that follow you across the internet. It is no longer a research curiosity. It is infrastructure. And most people — including many professionals deploying it daily — still cannot explain, in plain terms, what it actually is.
Don’t Just Read About AI — Own It. Right Here
TL;DR
AI software is computer code that learns patterns from data to make decisions, predictions, or generate outputs — without being explicitly programmed for every scenario.
The global AI software market was valued at approximately $298 billion in 2024 and is projected to exceed $1 trillion by 2030 (IDC, 2024).
Three dominant types exist: narrow AI (task-specific), generative AI (content-creating), and agentic AI (goal-pursuing with tool use).
Real documented productivity gains exist: GitHub Copilot users completed tasks up to 55% faster in Microsoft's 2023 controlled study.
Most AI software still fails silently — it can produce confident wrong answers, reflect training biases, and degrade when data shifts.
Regulation is tightening fast: the EU AI Act became enforceable in August 2024, the first comprehensive AI law in the world.
What is AI software?
AI software is a category of computer programs that use machine learning, neural networks, or rules-based logic to perform tasks that normally require human intelligence — such as recognizing images, understanding language, generating content, or making predictions — by learning patterns from large datasets rather than following fixed, hand-written instructions.

Background & Definitions
What Does "AI" Actually Mean?
Artificial intelligence, as a field of computer science, was formally defined at the 1956 Dartmouth Conference organized by John McCarthy, Marvin Minsky, Claude Shannon, and Nathaniel Rochester. McCarthy described it as "the science and engineering of making intelligent machines." For decades, that meant writing explicit rules: if X happens, do Y. This is called rule-based or symbolic AI.
The field shifted dramatically in the 1980s and 1990s when researchers began feeding computers large amounts of data and letting them find their own rules — a method called machine learning. Instead of programming "a cat has pointed ears, whiskers, and fur," engineers fed the system millions of cat images and let it figure out the patterns.
What is AI Software, Precisely?
AI software is any application or program that uses one or more of the following techniques to perform intelligent tasks:
Machine learning (ML): The program learns from data. It improves with more examples.
Deep learning: A subtype of ML using artificial neural networks with many layers. Powers image recognition and large language models.
Natural language processing (NLP): Enables computers to read, understand, and generate human language.
Computer vision: Enables machines to interpret visual information from images or video.
Reinforcement learning: The software learns by trial and error, receiving rewards for correct actions.
Generative AI: Produces new content — text, images, audio, code, video — based on patterns learned from training data.
The key distinction from traditional software: traditional software follows instructions you write. AI software derives its instructions from data.

How AI Software Works
The Training Phase
AI software does not arrive pre-programmed with knowledge. It learns. The training process works like this:
Data collection: Engineers gather large datasets relevant to the task — millions of labeled medical scans, billions of lines of text, thousands of hours of speech.
Model architecture selection: A mathematical structure is chosen (e.g., a transformer neural network, a decision tree, a convolutional neural network).
Training: The model processes the data repeatedly, adjusting millions or billions of internal numerical parameters (called weights) to minimize prediction errors. This requires enormous computing power.
Validation: The trained model is tested on data it has never seen to measure how well it generalizes.
Deployment: The model is integrated into software that end users interact with via an interface — a chatbot, API, app, or embedded tool.
The Inference Phase
Once deployed, the AI runs in "inference mode." It takes a new input — your question, your image, your transaction — runs it through the trained model, and produces an output. This is what happens when you type into ChatGPT, scan a receipt with an expense app, or get a fraud alert from your bank.
Why Scale Matters
Training modern large language models (LLMs) requires extraordinary compute. GPT-4, released in March 2023, was estimated by researchers at the University of Washington to have been trained on approximately 1 trillion parameters and required thousands of NVIDIA A100 GPUs for months (Epoch AI, 2023). This scale is why companies like Google, Microsoft, Amazon, and Meta spend tens of billions annually on AI infrastructure. Google's parent Alphabet reported $52.5 billion in capital expenditure for 2024, much of it AI-related data center investment (Alphabet 10-K, February 2025).
Types of AI Software
Narrow AI (Weak AI)
This is the most common form. Narrow AI is designed for one specific task and performs it extremely well — but cannot do anything outside that task.
Examples:
Spam filters: Gmail's spam detection uses ML trained on billions of emails. Google reported its filters block over 99.9% of spam (Google Workspace blog, 2023).
Recommendation engines: Netflix's recommendation algorithm influences approximately 80% of content watched on the platform (Netflix Tech Blog, 2016 — still widely cited in 2024 industry literature).
Speech recognition: Apple Siri, Amazon Alexa, and Google Assistant all use narrow AI for voice commands.
Generative AI creates new content — text, images, code, audio, video — by learning the statistical patterns in training data.
Key systems (as of 2026):
Large Language Models (LLMs): OpenAI GPT-4o, Anthropic Claude 3.7, Google Gemini 2.0, Meta Llama 3
Image generation: Midjourney, DALL-E 3, Stable Diffusion
Code generation: GitHub Copilot, Cursor, Replit AI
Video generation: Sora (OpenAI), Runway, Google Veo 2
Generative AI investment surged from $2.5 billion in 2022 to $36 billion in 2023, according to McKinsey's State of AI 2024 report.
Agentic AI
Agentic AI is the newest frontier. These systems do not just answer questions — they take sequences of actions, use external tools (search, code execution, email), and pursue multi-step goals with limited human supervision.
Examples:
OpenAI's Operator (launched January 2025) can browse the web and complete tasks like booking travel.
Anthropic's Claude with computer use (launched October 2024) can control a computer screen to complete tasks.
Microsoft Copilot Agents embedded in Microsoft 365 can draft emails, retrieve documents, and summarize meetings autonomously.

Key Drivers of AI Software Growth
1. Exponential Growth in Training Data
The internet produces approximately 2.5 quintillion bytes of data daily (World Economic Forum, 2024). This data — text, images, video, transactions — is the fuel for AI models. More data enables better pattern recognition.
2. Cheaper and More Powerful Compute
NVIDIA's H100 GPU, released in 2022, is approximately 30x faster for AI inference than the V100 released in 2017 (NVIDIA technical documentation, 2023). The cost of training a given model size has fallen roughly 2–3x per year over the past decade (Epoch AI, 2024).
3. Open-Source Democratization
Meta released the weights of Llama 3 in April 2024, a model that rivals closed commercial models. As of mid-2024, Hugging Face hosted over 500,000 publicly available models (Hugging Face blog, 2024). This allows small teams to build AI software without billion-dollar budgets.
4. Cloud API Access
Companies like OpenAI, Anthropic, and Google offer their AI via API — a technical interface that lets developers plug AI capabilities into their own software in hours rather than years. This has collapsed the barrier to building AI-powered products.
5. Regulatory and Board-Level Pressure
McKinsey's 2024 survey found that 72% of executives said AI was a top-three strategic priority for their organizations — up from 34% in 2022. Board-level attention is driving accelerated enterprise adoption.
Real Case Studies
Case Study 1: GitHub Copilot at Accenture
What happened: GitHub and Microsoft conducted a controlled productivity study of GitHub Copilot — an AI coding assistant — in 2023. Accenture was among the early enterprise adopters deploying Copilot to thousands of developers.
The data: In GitHub's controlled experiment (published September 2023), developers using Copilot completed a JavaScript task 55.8% faster than the control group. The study involved 95 professional developers split into Copilot and non-Copilot groups performing identical tasks.
Outcome: Accenture committed to deploying GitHub Copilot to 50,000 developers by the end of 2024 (GitHub Blog, September 2023). Microsoft reported GitHub Copilot generating $1.5 billion in annual recurring revenue by late 2024 (Bloomberg, November 2024).

Case Study 2: Google DeepMind AlphaFold and Drug Discovery
What happened: In 2020, Google DeepMind's AlphaFold 2 solved the protein folding problem — predicting the 3D shape of proteins from their amino acid sequence with near-experimental accuracy. This had stumped biologists for 50 years.
The data: By July 2024, the AlphaFold Protein Structure Database contained over 200 million protein structure predictions covering virtually all known proteins on Earth (DeepMind, July 2024). Over 1.7 million researchers in 190 countries had accessed the database by that date.
Real-world outcome: Eroom's Law (the reverse of Moore's Law for drug discovery) had documented that the cost of developing a new drug doubled every 9 years. AlphaFold is being used at Eli Lilly, AstraZeneca, and GSK to accelerate target identification. DeepMind's spin-out Isomorphic Labs signed deals with Eli Lilly ($1.7 billion) and Novartis ($1.2 billion) in January 2024 to co-develop drugs using AlphaFold-derived models (Reuters, January 2024).
Recognition: The 2024 Nobel Prize in Chemistry was awarded to Demis Hassabis and John Jumper (DeepMind) alongside David Baker for computational protein design (Nobel Committee, October 2024).

Case Study 3: Klarna's AI Customer Service Deployment
What happened: Klarna, the Swedish buy-now-pay-later company, deployed an OpenAI-powered customer service AI assistant in February 2024. The company made its results public — one of the most detailed real-world disclosures of enterprise AI performance to date.
The data (from Klarna's own press release, February 27, 2024):
The AI handled 2.3 million customer service conversations in its first month — equivalent to the work of 700 full-time human agents.
It resolved issues in under 2 minutes, compared to an 11-minute average for human agents.
Customer satisfaction scores were equal to those of human agents.
Klarna reported it was on track to improve profit by $40 million in 2024 as a result.
Context: Klarna had approximately 5,000 customer service employees at the time. CEO Sebastian Siemiatkowski told Bloomberg in March 2024 that the company had reduced its overall headcount from 5,000 to 3,800 partly due to AI, with no new hiring in customer service roles.

Industry Applications
Healthcare
AI software is FDA-cleared for diagnostic use across multiple modalities. As of December 2023, the FDA had authorized over 882 AI/ML-enabled medical devices — up from just 6 in 2015 (FDA AI/ML Action Plan, January 2024). Examples include Aidoc's radiology AI, which flags critical findings like pulmonary embolism, and IDx-DR, the first FDA-cleared autonomous AI diagnostic system, for diabetic retinopathy screening.
Finance
JPMorgan Chase's COIN (Contract Intelligence) software, deployed in 2017, processes 12,000 commercial credit agreements in seconds — work that previously took lawyers 360,000 hours annually (Harvard Business Review, 2017). By 2024, JPMorgan employs over 2,000 AI and ML engineers (JPMorgan Chase 2024 Annual Report).
Retail & E-Commerce
Amazon's recommendation engine, powered by collaborative filtering ML models, is attributed to generating 35% of the company's total revenue (McKinsey & Company, 2019 — widely cited in subsequent industry literature). Amazon uses AI across demand forecasting, warehouse robotics, dynamic pricing, and Alexa.
Manufacturing
Siemens uses AI-powered quality inspection systems across its factories. Its MindSphere IoT and AI platform processes data from millions of connected devices to predict equipment failures before they happen. Siemens reported predictive maintenance cut unplanned downtime by up to 30% in documented pilot deployments (Siemens AG press materials, 2023).
Education
Duolingo's AI-powered language learning app uses spaced repetition algorithms and, since 2023, GPT-4 for conversational practice. Duolingo Max (launched March 2023) uses GPT-4 for "Roleplay" and "Explain My Answer" features. As of 2024, Duolingo has 97.6 million monthly active users (Duolingo Q3 2024 earnings report).

Cybersecurity risk | Adversarial attacks can fool AI vision systems with minor image perturbations (Goodfellow et al., 2014) |
Myths vs. Facts
Myth 1: "AI software understands language the way humans do."
Fact: Large language models predict the next token (word fragment) based on statistical patterns. They do not "understand" meaning. This is why they can produce fluent, confident nonsense. Linguist Emily Bender and colleagues coined the term "stochastic parrots" in a 2021 paper (Bender et al., ACL 2021) to describe this behavior.
Myth 2: "AI will soon replace all human jobs."
Fact: The World Economic Forum's Future of Jobs Report 2023 projects that AI will displace 85 million jobs and create 97 million new ones by 2025. Net effect: positive, but with massive skill transitions required. Historical automation waves (e.g., ATMs and bank tellers — teller employment actually rose from 1970 to 2010, per James Bessen's research at BU Law) suggest AI augments more than it eliminates in most sectors.
Myth 3: "AI software is always objective because it uses math."
Fact: AI reflects the data it was trained on. If that data encodes human bias, the AI reproduces and often amplifies it. The ProPublica COMPAS investigation (2016) found that a widely used criminal recidivism AI was twice as likely to falsely flag Black defendants as high risk compared to white defendants.
Myth 4: "You need a computer science degree to use AI software."
Fact: No-code AI platforms like Make (formerly Integromat), Zapier AI, and Microsoft Copilot allow non-technical users to deploy AI workflows. ChatGPT itself requires zero technical knowledge to operate.
Myth 5: "More data always makes AI better."
Fact: Quality matters more than quantity. A 2023 paper from Eleuther AI and academic collaborators showed that smaller models trained on carefully curated, high-quality datasets (called "chinchilla-optimal" training) outperform larger models on noisier data.

Pitfalls & Risks
1. Hallucination in High-Stakes Contexts
AI language models fabricate facts with confidence. In June 2023, New York lawyer Steven Schwartz filed a legal brief in federal court that cited six entirely fake cases — all invented by ChatGPT. The judge fined Schwartz's firm $5,000 (United States District Court, Southern District of New York, Mata v. Avianca, June 2023). This is not a fringe event. Always verify AI outputs against authoritative sources before acting on them in legal, medical, or financial contexts.
2. Data Privacy Violations
Italy's data protection authority (Garante) temporarily banned ChatGPT in March 2023 over GDPR violations, becoming the first Western regulator to do so. OpenAI was required to implement new user controls before service was restored (Garante, April 2023). Feeding customer data into public AI APIs without proper data processing agreements can expose companies to significant regulatory liability under GDPR and equivalent laws.
3. Model Drift
AI models are trained on historical data. When the world changes — new terminology, new fraud patterns, new consumer behavior — models become less accurate. This is called distribution shift or model drift. Regular monitoring, benchmarking, and retraining schedules are essential for production AI systems.
4. Vendor Lock-In
If your AI software is built entirely on a proprietary API (e.g., OpenAI), and that vendor raises prices, changes terms, or suffers an outage, your operations are exposed. OpenAI experienced multiple significant outages in 2023–2024 (documented on its status.openai.com page). Mitigation strategies include multi-vendor architectures or open-source model fallbacks.
5. Adversarial Attacks
AI systems, particularly vision and NLP models, can be deliberately manipulated with adversarial inputs — carefully crafted inputs that fool the model. Researchers at MIT and other institutions have shown that adding subtle noise to an image (invisible to humans) can cause an AI vision system to misclassify a stop sign as a speed limit sign (Eykholt et al., 2018, IEEE CVPR). This is particularly relevant for autonomous vehicles and security systems.
Future Outlook
Near-Term (2026–2028)
Multimodal AI becomes standard. Models that simultaneously process text, images, audio, video, and structured data are replacing single-modality models. Google Gemini 1.5 Pro (February 2024) demonstrated processing of 1 million tokens — enough to ingest an entire codebase or a full-length film — in a single context window.
Agentic AI expands. By late 2025, multiple companies had deployed AI agents that operate software, schedule tasks, and complete workflows with minimal oversight. Gartner predicts that 15% of day-to-day work decisions will be made autonomously by AI agents by 2028 (Gartner, October 2024).
On-device AI grows. Apple Intelligence (launched 2024) processes many AI tasks locally on device, avoiding cloud transmission. Qualcomm's Snapdragon X Elite chip includes a dedicated Neural Processing Unit (NPU) designed for on-device AI inference. This reduces latency, cost, and privacy exposure.
Regulatory enforcement intensifies. The EU AI Act's high-risk AI provisions began phased enforcement in 2025. China's Interim Measures for Generative AI Services (effective August 2023) requires AI providers to register models with the government. The US lacks comprehensive federal AI legislation as of early 2026, but sector-specific guidance from the FDA, FTC, and NIST is expanding.
Energy and sustainability pressure. Goldman Sachs projected in April 2024 that data center power demand from AI would increase by 160% by 2030. This is driving investment in nuclear energy for data centers — Microsoft signed a 20-year deal to restart Three Mile Island's Unit 1 reactor in September 2024 (Microsoft blog, September 2024).
Longer-Term Questions (Post-2028)
The AI research community actively debates the path toward Artificial General Intelligence (AGI) — systems that can perform any intellectual task a human can. OpenAI, DeepMind, and Anthropic each publish internal assessments of AGI timelines. There is no scientific consensus on when or whether AGI will be achieved. What is documented is that capability gains have been faster than most researchers predicted five years ago.
FAQ
1. What is the difference between AI software and regular software?
Regular software follows explicit rules written by programmers: "If X, then Y." AI software learns its own rules from data. A traditional spam filter might block emails containing specific words you listed. An AI spam filter learns patterns from millions of spam and non-spam emails and catches novel spam it has never seen before.
2. Is AI software the same as machine learning?
Machine learning is one method used to build AI software, not a synonym. AI software can also use rule-based logic, expert systems, or statistical models that are not machine learning. Machine learning is the dominant technique today, but it is a subset of AI, not the whole field.
3. What is a large language model (LLM)?
An LLM is a type of AI trained on enormous amounts of text data to predict and generate human language. GPT-4, Claude 3, Gemini, and Llama 3 are all LLMs. They can write, summarize, translate, answer questions, and generate code. They work by predicting the most probable next word (or token) given the words before it.
4. How do AI software companies make money?
Primarily through three models: API pricing (charge per token or query — OpenAI, Anthropic, Google), SaaS subscriptions (monthly/annual seat fees — GitHub Copilot at $19/month per developer), and enterprise licensing (custom contracts with large organizations — common for IBM, Salesforce, Microsoft).
5. Can AI software be biased?
Yes, and the bias is well-documented. AI systems reflect the biases present in their training data. Amazon's now-abandoned hiring AI downgraded resumes from women (Reuters, October 2018). COMPAS, used in US courts for recidivism prediction, showed racial disparities (ProPublica, 2016). Bias mitigation is an active research and regulatory area.
6. Is AI software safe to use for medical decisions?
The FDA has cleared over 882 AI/ML-enabled medical devices as of December 2023, but clearance means the device met specific safety and effectiveness criteria for its approved use — not that it is infallible. Clinicians are expected to use AI as a decision-support tool, not a replacement for clinical judgment. Always follow guidance from your institution and relevant regulatory bodies.
7. What programming languages are used to build AI software?
Python is the dominant language for AI development. Key libraries include PyTorch (Meta), TensorFlow (Google), and Hugging Face Transformers. R is used in statistical ML. C++ and CUDA are used for performance-critical components. JavaScript (via TensorFlow.js) enables browser-based AI.
8. How much does AI software cost to build?
It depends heavily on approach. Using a pre-trained API (e.g., OpenAI's GPT-4o API), a functional AI application can be built for minimal fixed cost — pay-per-use pricing starts at fractions of a cent per query. Fine-tuning an existing open-source model on proprietary data costs $5,000–$100,000+ depending on dataset size and compute. Training a frontier model from scratch costs hundreds of millions to billions of dollars.
9. What is the EU AI Act?
The EU AI Act, formally Regulation (EU) 2024/1689, is the world's first comprehensive AI law. It entered into force on August 1, 2024, with phased enforcement through 2027. It classifies AI systems by risk level: unacceptable risk (banned — e.g., social scoring), high risk (strictly regulated — e.g., medical devices, employment AI), limited risk (transparency requirements), and minimal risk (largely unregulated). Violations can result in fines up to €35 million or 7% of global annual revenue.
10. What is "hallucination" in AI software?
Hallucination refers to AI systems — particularly LLMs — generating factually incorrect information confidently. The model does not "know" it is wrong; it is predicting plausible-sounding text, not retrieving verified facts. Documented examples include fake legal citations (Mata v. Avianca, 2023) and fabricated medical study references. Mitigation approaches include retrieval-augmented generation (RAG), which grounds responses in verified source documents.
11. What is the difference between AI software and automation?
Traditional automation executes predefined, fixed rules — a script that fills in a form the same way every time. AI software adapts — it makes judgments based on patterns, can handle variation, and improves with more data. The two are often combined: robotic process automation (RPA) with AI overlay is called "intelligent automation."
12. Can small businesses use AI software?
Yes. The barrier to entry has collapsed. Tools like ChatGPT Plus ($20/month), Canva AI (built into free tiers), HubSpot AI CRM tools, and Shopify Magic (AI product descriptions) are accessible with no technical background. Open-source models like Llama 3 can be run locally on a consumer laptop using tools like Ollama — free and private.
13. What is retrieval-augmented generation (RAG)?
RAG is a technique that combines an LLM with a search system. Instead of relying solely on what the model "memorized" during training, RAG retrieves relevant documents from a knowledge base at query time and feeds them to the model as context. This dramatically reduces hallucination for domain-specific applications and allows the model to answer questions about current events or proprietary data it was never trained on.
14. How is AI software regulated in the United States?
The US does not have a comprehensive federal AI law as of early 2026. Instead, AI is regulated sector-by-sector: the FDA governs AI medical devices, the FTC enforces against deceptive AI practices, the EEOC covers AI in hiring, and financial regulators cover AI in lending. President Biden's Executive Order on AI (October 2023) established reporting requirements for large AI model developers. The Trump administration's repeal of that order in January 2025 shifted federal policy toward a more permissive approach (Reuters, January 2025).
15. What is open-source AI software?
Open-source AI software makes model weights, training code, or both publicly available for anyone to download, modify, and deploy. Meta's Llama series, Mistral models, and Stability AI's Stable Diffusion are prominent examples. Open-source AI enables customization and privacy (run locally) but requires technical expertise and compute resources. As of mid-2024, Hugging Face hosted over 500,000 open-source models.
Key Takeaways
AI software learns from data rather than following pre-written rules — this is the fundamental distinction from traditional software.
The global AI software market exceeded $298 billion in 2024 and is on track to surpass $1 trillion by 2030 (IDC, 2024).
Narrow AI, generative AI, and agentic AI represent three distinct and coexisting generations of AI software, each with different capabilities and limitations.
Real productivity gains are documented: GitHub Copilot accelerated coding tasks by 55.8% in controlled trials; Klarna's AI handled the workload of 700 agents in one month.
AlphaFold earned a Nobel Prize in Chemistry in 2024, proving AI software can solve problems that stumped human science for half a century.
Hallucination, bias, data drift, and adversarial vulnerability are documented failure modes that require active management — not afterthoughts.
The EU AI Act (effective August 2024) is the first comprehensive AI law globally, creating enforceable obligations for AI developers and deployers worldwide who serve EU users.
Energy consumption is a serious and growing constraint: AI-driven data center power demand is projected to rise 160% by 2030 (Goldman Sachs, 2024).
Open-source models have democratized AI software development — competitive models now run on consumer laptops, free of charge.
Agentic AI — systems that take multi-step actions autonomously — is the active frontier as of 2026, introducing new capabilities and new risks simultaneously.
Actionable Next Steps
Audit your current software stack. Identify where AI is already embedded (email spam, CRM scoring, ad targeting) and whether you understand how those systems make decisions.
Start with one use case. Pick one repetitive, high-volume task in your workflow. Evaluate whether an off-the-shelf AI tool addresses it — before building anything custom.
Test with real data. Run a 30-day pilot of any AI software tool using your actual data and workflows. Measure error rates, time savings, and user satisfaction quantitatively.
Read the privacy terms. Before inputting customer or proprietary data into any AI API, confirm the vendor's data retention policy, GDPR/CCPA compliance status, and data processing agreement.
Implement a human review step. For any AI output used in customer-facing, financial, medical, or legal contexts, define an explicit human sign-off protocol before deployment.
Monitor for model drift. Set a schedule (quarterly minimum) to benchmark your AI system's accuracy against current data. Retrain or switch models if performance degrades.
Upskill your team. Enroll at least one team member in a structured AI literacy program. Google's "Introduction to Generative AI" (free, available on Google Cloud Skills Boost) and DeepLearning.AI's short courses are well-regarded starting points.
Track regulation in your jurisdiction. Subscribe to updates from the EU AI Office (if operating in Europe), the FTC (US), and your sector-specific regulator. Non-compliance costs are now quantifiable and significant.
Explore open-source options. Before committing to expensive proprietary APIs, evaluate whether an open-source model (Llama 3, Mistral) meets your needs — with full data control and no per-query costs.
Document your AI use. For every AI system you deploy, document: what it does, what data it uses, who is accountable for its outputs, and how errors are escalated. This is increasingly required by law and is always good practice.
Glossary
Algorithm: A set of mathematical rules or instructions a computer follows to solve a problem or make a decision.
Agentic AI: AI systems that take sequences of actions autonomously to accomplish multi-step goals, often using external tools like web browsers, code interpreters, or APIs.
Benchmark: A standardized test used to measure and compare the performance of AI systems. Examples include MMLU (language understanding) and ImageNet (image classification).
Black box: An AI system whose internal decision-making process is not interpretable or explainable by humans.
Data drift (distribution shift): The degradation of an AI model's accuracy over time because real-world conditions change while the model's training data remains static.
Deep learning: A type of machine learning that uses artificial neural networks with many layers to learn patterns from large datasets. Foundational to modern image recognition, speech recognition, and LLMs.
Fine-tuning: Further training a pre-built AI model on a smaller, domain-specific dataset to improve its performance on a particular task.
Foundation model: A large AI model trained on broad data at scale (text, images, code) that can be adapted to many downstream tasks. GPT-4, Gemini, and Claude are foundation models.
Generative AI: AI that creates new content — text, images, audio, video, code — by learning statistical patterns from training data.
Hallucination: When an AI language model generates factually incorrect information with apparent confidence.
Inference: The process of running a trained AI model on new inputs to produce outputs. Distinct from training.
Large Language Model (LLM): A type of AI model trained on massive text corpora to understand and generate human language. Powers ChatGPT, Claude, Gemini, and similar systems.
Machine learning (ML): A branch of AI where systems learn from data to improve performance on a task without explicit programming.
Model drift: See data drift.
Natural Language Processing (NLP): A field of AI focused on enabling computers to understand, interpret, and generate human language.
Neural network: A computational architecture loosely inspired by biological neurons, consisting of interconnected layers of mathematical nodes that transform inputs into outputs.
Parameters (weights): The numerical values inside an AI model that are adjusted during training. A model's "size" is often described by its number of parameters (e.g., GPT-3 had 175 billion parameters).
Prompt: The input or instruction given to an AI system, particularly a language model. Prompt engineering is the practice of crafting effective prompts to improve AI outputs.
RAG (Retrieval-Augmented Generation): A technique that enhances LLMs by retrieving relevant documents from an external database at query time, reducing hallucination and enabling access to current or proprietary information.
Reinforcement learning: A training approach where an AI agent learns by taking actions in an environment and receiving rewards or penalties based on outcomes.
Token: The basic unit of text that LLMs process — roughly 0.75 words in English. Pricing for LLM APIs is typically per token.
Training data: The dataset used to teach an AI model. Its quality, size, and diversity directly determine the model's capabilities and biases.
Transformer: The neural network architecture introduced in the 2017 Google paper "Attention Is All You Need" that underpins virtually all modern LLMs.
