AI Glossary — Practical Keywords for Sales

Definitions for terms you'll use in customer conversations, organized into 6 categories: 1. Fundamentals -> 2. Model makers -> 3. Cloud platforms -> 4. Latest engineering terms -> 5. Risk -> 6. Latest products. Especially in sensitive projects (e.g. My Number), the katakana terms in category 3 (Bedrock, region, etc.) always come up. Use the buttons above to jump between categories. Even just the bold one-liners will keep you in the conversation.

1. Fundamentals

The foundation for talking about AI at all. Start here.

1
AI (Artificial Intelligence)Artificial Intelligence

Computer technology that can learn and make decisions like humans

Covers image recognition, voice recognition, text generation, prediction, and more. In today's business context, "AI" mostly means Generative AI and AI Agents.

2
Generative AIGenerative AI

AI that creates text, images, and code — ChatGPT is the familiar example

Traditional AI focused on classification and prediction. Generative AI is revolutionary because it creates new content: drafting, summarization, translation, code generation.

3
LLM (Large Language Model)Large Language Model

The engine inside Generative AI. GPT, Claude, Gemini are examples

Models trained on vast internet text. The model you choose changes cost, accuracy, and speed. Providers (2) build them; you call them via a cloud (3).

4
TokenToken

The smallest unit an AI processes. LLM cost is billed per token

Roughly 1 English word ≈ 1–2 tokens. LLMs bill on input + output tokens. Processing large volumes drives up cost, so token-reduction design is the core of cost control. Adsur has shown 75% reduction on real workloads.

5
PromptPrompt

The instruction text sent to an AI — quality directly drives output quality

How you ask matters enormously. Prompt engineering improves both accuracy and token efficiency — a key skill for enterprise AI.

6
Context WindowContext Window

The max amount of info an AI can read at once — its "short-term memory"

Each model has a limit (e.g. hundreds of thousands of tokens = hundreds of book pages). Exceed it and older content is "forgotten." For long documents or chat histories, balancing this limit against token cost matters.

7
RAG (Retrieval-Augmented Generation)Retrieval-Augmented Generation

A way to let AI "read" your internal documents — cheaper than fine-tuning

Relevant internal docs are searched, then handed to the AI. Turn manuals, policies, and past cases into a knowledge base for accurate answers. Greatly reduces hallucination (5).

8
Fine-tuningFine-tuning

Additional training on an existing LLM to specialize it for a task

Bakes business data into the model itself. Higher accuracy, but heavier cost, time, and retraining burden. Most business cases are well served by low-cost RAG first; fine-tuning is the option when RAG can't reach.

2. Model Makers (Providers)

The companies building the LLM "brains" and their flagship models.

1
OpenAI (GPT)OpenAI / GPT series

The company behind ChatGPT. Model names like "GPT-4o", "GPT-5"

The spark of the GenAI boom. GPT models are highly general and the best-known brand. Usable via API, but enterprises mostly consume them through Microsoft's Azure OpenAI (3). "We want ChatGPT" usually means this family.

2
Anthropic (Claude)Anthropic / Claude series

Builds Claude — strong on safety, long context, and coding. Adsur's primary model

Tiers: Opus (top performance) / Sonnet (balanced) / Haiku (fast, low-cost). Excellent at long-document work and code, and available on AWS Bedrock (3), making it a great fit for sensitive projects. Adsur's most-used model.

3
Google (Gemini)Google / Gemini series

Google's flagship — handles text, image, audio, and video together

Tiers like Pro (performance) / Flash (fast, low-cost). Strong at multimodal and very long context. Used via Google Cloud's Vertex AI (3). A candidate when Google Workspace / YouTube integration is involved.

4
Meta (Llama) / Open ModelsMeta / Llama, Open Models

Freely published "open-weight" models you can host yourself

Meta's Llama is the flagship. You can host the model on your own servers/cloud, an option when data must never leave for an external API. The trade-off: you bear the operations and GPU cost. Choosing vs. commercial models (GPT/Claude/Gemini) is the debate.

3. Cloud Platforms & AI Services

Where AI runs — this layer decides environment, cost, and how sensitive data is handled.

1
Cloud / On-PremisesCloud / On-Premises

Renting compute in a provider's data center vs. running servers in your own building

Cloud = rent AWS/Azure/Google infrastructure over the internet (low upfront cost, easy to scale). On-prem = servers in your own facility. "Cloud or on-prem?" is the basic question that sets where AI can run and where data lives.

2
AWS / Azure / Google CloudThe Big 3 Cloud Platforms

The three dominant providers — the ones you meet most in enterprise and government deals

AWS (Amazon), Azure (Microsoft), Google Cloud (GCP) hold most of the market. Which cloud a customer uses shapes available AI services and the path forward. Sensitive workloads often run on AWS/Azure; Microsoft 365 shops pair well with Azure.

3
Amazon BedrockAWS — Amazon Bedrock

AWS managed service to call LLMs like Claude securely on AWS

AWS's "gateway to GenAI." Call Claude, Llama, Amazon Nova via API. Key point: data stays within your AWS environment and isn't used for training — a frequent pick for My Number, healthcare, and finance. If a customer says "Amazon's… Bedrock?", this is it.

4
Azure OpenAI / Azure AI FoundryMicrosoft Azure

Microsoft's AI platform — use GPT securely inside Azure

Azure OpenAI runs GPT models inside Microsoft's environment. Azure AI Foundry (formerly AI Studio) bundles model selection, RAG, agent building, and evaluation into one dev platform. Great fit for Microsoft 365 / Copilot shops. Note: Copilot (SaaS) and API use are separate contracts (6).

5
Google Cloud Vertex AIGoogle Cloud — Vertex AI

GCP's AI platform — the gateway to using Gemini in an enterprise

Vertex AI bundles Gemini (2) and other models with RAG, agents, and MLOps on Google Cloud. A candidate for Google Workspace / BigQuery integration. It appeared as the pre-existing environment in a government agency PoC.

6
Region / Data ResidencyRegion / Data Residency

Which country/area your data physically lives in — top concern for sensitive projects

Clouds run in regions worldwide. Choosing the "Tokyo region" keeps data in Japan. My Number and similar data often legally cannot leave the country, making region choice a prerequisite for the deal. Always confirm this.

7
SaaS / Managed ServiceSaaS / Managed Service

"Use a finished product monthly" vs. "rent parts and build it yourself"

SaaS = a finished product used monthly over the internet (e.g. Microsoft 365). Managed = renting provider-run building blocks (e.g. Bedrock, Document Intelligence) to assemble your own system. "License Copilot and you get the GPT API too" is a myth — separate contracts. Matters for explaining cost.

4. GenAI Engineering Terms

New ways of building AI that emerged in 2024–2026. Adsur's core battlefield.

1
AI Agent (Agentic AI)Agentic AI / AI Agent

AI that autonomously executes multi-step tasks from an instruction

Not just "question → answer" but an autonomous loop of research → decide → run tools → verify. Used in automation, ops, and document review — Adsur's core solution area. "Agentic" is the buzzword for this autonomous quality.

2
Autonomous ExecutionAutonomous AI

How far AI proceeds to decide and act without step-by-step human input

Ranges from semi-autonomous (human approves key steps) to fully autonomous (no human in the loop). For business cases, start semi-autonomous — "AI proposes → human approves → execute" — it's safer and standard. Full autonomy spikes effort on exception handling.

3
AI Harness (Harness Engineering)AI Harness Engineering

The scaffolding that controls and constrains AI — structurally prevents cost blow-ups, misfires, and leaks

Not "build a better model" but "design an environment where AI runs safely, accurately, and cheaply." Proposed by OpenAI/Anthropic in 2025–2026. Adsur used it to hit 97.4% accuracy and 75% token reduction on Vex. Core of our in-house edge.

4
MCPModel Context Protocol

A standard "plug" for connecting AI agents to internal systems and tools

A standard proposed by Anthropic in 2024 for how AI connects to tools and data sources. Like a USB port — "support it once, swap connections easily." A major trend in agent development; pays off in automation with many integration points.

5
Multi-Agent / OrchestrationMulti-Agent / Orchestration

Splitting work across specialized AI agents, coordinated by a conductor

Divide labor across "researcher", "executor", "verifier" agents to raise accuracy and coverage. Orchestration is the coordination layer. Used for complex workflow automation; more robust than a single AI.

5. Risk & Quality Terms

How AI misbehaves — and how we contain it. The vocabulary to address customer fears.

1
HallucinationHallucination

When AI confidently generates false or fabricated information

AI can output plausible-sounding misinformation even when unsure. Mitigations: RAG (1) for grounded answers, mandatory citations, and rule-based validation. Adsur systems always attach source citations. The thing customers fear most.

2
Runaway BehaviorRunaway / Unintended Behavior

AI repeating unintended actions until cost or processing spirals out of control

An autonomous agent enters a bad loop, hammering an API and inflating cost, or takes unintended actions. Mitigations: harness (4) action limits, run caps, and human approval gates. This design is your answer to "won't it run wild if we let AI do everything?"

3
GuardrailsGuardrails

Safety "rails" on AI input/output — stop forbidden or sensitive content

Enforce rules: reject inappropriate input, detect/mask sensitive data (PII, My Number), block dangerous output. Adsur's in-house Aegis AI is a gateway built on this idea, detecting 19 PII types to prevent leaks.

4
Jailbreak / Prompt InjectionJailbreak / Prompt Injection

Crafted input that tries to bypass or hijack AI restrictions

Tricks like "ignore your previous instructions and…" try to strip guardrails. Essential to defend in AI that takes external input (chatbots). Defenses: input validation, privilege separation, output monitoring. A security question customers raise.

5
Token / Cost Blow-upToken / Cost Blow-up

Design mistakes in volume or loops that balloon token use — and cost

Main causes: dumping long text, needless re-sends, agents spinning. Prevent with token-reduction design (1) and harness caps. Adsur quotes split "development" vs "production (usage-based)". In OCR projects, per-page OCR fees can bite before LLM cost.

6. Latest Products & Concepts

Adjacent tech that shows up in deals, and the keywords coming next.

1
OntologyOntology

Structuring tech that connects scattered data by "meaning" — core of data-AI platforms

Represents relationships between concepts (customer, account, deal) as a graph. Lets AI use data across multiple systems that RAG alone can't bridge. Central to Palantir's data platform. A keyword for next-gen data projects.

2
Physical AIPhysical AI

AI that operates in the real, physical world — robots, autonomous transport, factory automation

Beyond the digital, it works with sensors, robot arms, and AGVs to automate physical tasks. NVIDIA's Cosmos (world models) and Isaac (robot simulation) are leading platforms. One of Adsur's focus areas.

3
Computer UseComputer Use

AI that sees a PC screen like a human and operates the mouse and keyboard

Recognizes screenshots to click and type, so it can drive systems that have no API. A next-gen take on RPA (6), drawing attention for office-task automation. Accuracy, speed, and stability are still maturing — verify before production use.

4
OCROptical Character Recognition

Turns text in paper/PDF/images into data — essential for automating forms

Scans forms to read "what is written where." Handwriting accuracy can make or break a project. Key cost point: OCR is usually billed per page and is often the main cost of one pipeline run (sometimes more than LLM tokens). "How many pages per month?" is the estimate's key.

5
APIApplication Programming Interface

The "connection port" through which systems exchange data

The entry point for calling AI or external services from a program. Whether a customer's system "has an API" is a fork for automation. API = clean, stable integration. No API = drive the human screen with a robot (RPA/Computer Use), adding constraints. "Does your system have an API?" is essential.

6
RPARobotic Process Automation

Software that mimics the clicks and typing a human does on a PC

For legacy systems without an API, RPA imitates human screen operations to auto-fill and transcribe. Caveat: most RPA assumes a human-logged-in screen, so fully unattended background runs can be hard. Simple transcription = RPA; if judgment is needed, combine with AI (4).

7
PoC / PoVProof of Concept / Proof of Value

Small pre-production trials. PoC = "can it be done technically"; PoV = "does it deliver business value"

PoC confirms technical feasibility; PoV focuses on real effect and ROI once deployed. Both are the on-ramp for "start small, convert to a production order" — Adsur's standard way to run AI deals.
