AI alignment: AI alignment is the work of making AI systems do what their users and makers actually intend, and not something harmful or unintended.

The model learns the pattern and then predicts the label for new examples. Learn it: AI Receipt Extractor: Receipts to Google Sheets with n8n
Support ticket: A support ticket is a single customer request or problem that is logged and tracked until it is solved. Each ticket holds the customer's message, a status such as open or closed, an owner and a history of every reply, so nothing gets lost between people or shifts. Learn it: n8n AI Email Responder: Draft Gmail Replies Automatically
Switch node: The Switch node in n8n sends each item down one of several outputs based on rules you set, like a mail sorter. Each routing rule gets its own output, plus an optional fallback output for items that match no rule, so repairs, emergencies and everything else can each go to different steps, people or sheets. Learn it: IF and Switch in n8n: Route Work by Rules
Synthetic data: Synthetic data is artificial data created to look and behave like real data: fake customers, invented invoices, made-up transcripts.

Test data: Test data is sample input, usually made up, that you use to check that an app, automation or AI workflow works before real data or customers touch it: a fake form entry, a practice email, a sample receipt.

Learn it: Turn a Client Kickoff Call into a Proposal Outline with ChatGPT (Agencies & Consultants)
Token: A token is a small chunk of text, often a whole short word or part of a longer one, that an AI language model reads and writes. Models count everything in tokens: the length of your prompt, the length of the reply, how much they can hold at once and, for API use, what you are billed. Learn it: Build an n8n AI Agent That Plans Your Content Calendar
Token pricing: Token pricing is the way AI companies charge for API use: a set price per million tokens of text you send in, and a separate, usually higher price per million tokens the model writes back. A token is roughly three quarters of an English word. Learn it: n8n AI Agent Tutorial: Save Social Media Ideas to Google Sheets
Tool calling: Tool calling is how an AI model uses outside functions. Instead of only writing text, it returns a structured request to run a specific tool with specific inputs, such as "append this row", and the surrounding software runs it and passes back the result. Learn it: AI Receipt Extractor: Receipts to Google Sheets with n8n
Top-k retrieval: Top-k retrieval means a search returns the k closest matches, such as the 4 chunks most similar to the question. The AI only sees those chunks. Learn it: Answer Staff Questions from Your Own Docs using n8n + Pinecone

Learn it: Get On-Brand Social Posts Every Time using a ChatGPT Custom GPT
Transformer model: A transformer is the neural network design that today's large language models are built on.
