AI Glossary
Understanding infrastructure helps designers appreciate performance constraints, cost considerations, and deployment options that affect product decisions. Hardware & Serving GPU (Graphics Processing Unit) Specialized processor for parallel calculations, dominant hardware for AI. GPUs excel at thousands of simultaneous calculations essential for neural networks. NVIDIA's H100 and A100 are
AI Glossary
This is probably the most important part of the glossary for designers and these patterns and principles are directly relevant to product design practice. Understanding them enables the creation of AI experiences that are useful, usable, and appropriately trusted. Interaction Patterns Conversational UI Interface paradigm where interaction occurs through natural
AI Glossary
These concepts are critical for responsible AI product development—understanding failure modes, safety measures, and evaluation approaches directly informs design decisions. Safety Concepts AI Safety The interdisciplinary field preventing accidents, misuse, or harmful AI consequences. Encompasses alignment research, risk monitoring, robustness, and developing norms for beneficial AI operation. Reference: Amodei,
AI Glossary
Understanding how models are built and adapted helps designers recognize capability sources, appreciate customization options, and understand training-related behaviors and limitations. Pre-Training Concepts Pre-training The initial, computationally intensive phase of training on massive unlabeled text. During pre-training, models learn language patterns, grammar, factual knowledge, and reasoning capabilities by processing billions
AI Glossary
Understanding how LLMs are built helps designers grasp capability limits, performance tradeoffs, and why certain behaviors emerge. This section covers the core concepts that explain how modern AI models work. Core Architecture Transformer Architecture The neural network design that revolutionized AI, introduced in 2017's "Attention Is All
AI Glossary
Understanding the AI landscape helps designers navigate vendor decisions, cost considerations, and market dynamics. Here are a bunch of foundational concepts that we should all have some awareness of. No need to learn them by heart, but this is a good reference manual with references where possible. Foundation Models Large-scale
AI Glossary
The agentic paradigm represents a fundamental shift from reactive chatbots to proactive AI systems that can plan and execute multi-step tasks. AI Agents / Agentic AI Systems autonomously planning, deciding, and acting to accomplish goals—moving beyond single-response chatbots to multi-step problem solvers. Combine LLMs (reasoning), tools (actions), and memory (context)
