You use AI every day, but do you know what an LLM is?
An LLM (Large Language Model) is an AI model trained on large amounts of text data to understand and generate human-like language.
Examples include ChatGPT, Google Gemini, Claude, and Grok.

What is an AI Chain, and how does it work?
An AI chain is a predefined sequence of steps that passes information from one component to the next to complete a specific task. Each execution starts fresh, so it doesn’t retain memory of previous conversations or past executions.

What Are AI Embeddings and How Do They Work?
An AI embedding is a numerical representation of data, such as text, images, audio, or video, encoded as a vector, which is a list of numbers. Embeddings help AI capture patterns and relationships in data, making it possible to find similar information based on meaning rather than exact words.
[Example: Finding a Refund Policy]
A company stores its refund policy in a vector database. The text is converted into an embedding, which is represented as a vector of numbers.
A customer asks, “How can I get my money back?” The system converts this question into another embedding.
The system compares the question’s vector with the stored vectors and finds that the refund policy is the most semantically similar information, even though the words “money back” and “refund” are different.
The relevant refund policy is retrieved and given to the AI, which uses it to generate an appropriate response for the customer.

What is AI Groundedness, and why does it matter?
AI Groundedness is the measure of how well an AI-generated answer is supported by the information available in its provided or retrieved sources. A grounded answer is based on and supported by those sources, while an ungrounded answer contains claims, guesses, hallucinations, or details that are not supported by the available information.
[Example of AI Groundedness]
Source: “Our company offers AI Automation and AI Consulting.”
Question: “What services do we offer?”
Grounded answer: “You offer AI Automation and AI Consulting.”
[Ungrounded Answer]
AI says: “You offer AI Automation, AI Consulting, and AI Website Development.”
Why? AI Website Development was never mentioned in the source, so the answer is ungrounded.
[Key Idea]
AI Groundedness ensures that AI answers are supported by reliable sources and evidence rather than unsupported claims or guesses.

What is an AI hallucination, and why does it happen?
AI hallucination is when an LLM (Large Language Model) generates false or made-up information and presents it as if it were true.
[Example]
You ask an AI, “What are the side effects of a fictional medicine called X?” The AI may confidently provide a list of side effects, even though the medicine doesn’t exist. It has generated information that sounds real but is completely made up.

How does AI reranking improve search results?
AI reranking is the process of using an AI model to reevaluate and reorder an initial set of search results based on their relevance to a user's query.
[Example]
You search: “Best AI automation tools for small businesses.”
The search system first retrieves a set of potentially relevant results. However, the initial ranking may not perfectly reflect which results are most relevant to your specific query and intent.
An AI reranker then analyzes the retrieved results in relation to your query. It can consider factors such as semantic meaning, context, and relevance to determine which results best match what you’re looking for.
The reranker then reorders the results based on its relevance assessment. Results that better match your query move higher, while less relevant results move lower.
This helps the search system prioritize results that better match your actual search intent, rather than relying only on the initial ranking.
That’s the value of AI reranking.

What is AI memory, and how does it work?
AI memory allows an AI to retain and use relevant information from previous messages or interactions, so it can continue a conversation without you having to provide the same context again and again.
In n8n, AI Agent nodes can use memory, but AI Chain nodes can't.

What is RAG (Retrieval-Augmented Generation), and how does it work?
RAG (Retrieval-Augmented Generation) is a technique that lets an AI retrieve relevant information from external sources and use it to generate more accurate and contextually relevant responses. RAG systems often use vector databases to efficiently store, manage, and search this external information.
[Why RAG?]
AI models may lack access to specific or recently updated information. RAG addresses this by retrieving relevant information from external sources and providing it to the AI as additional context.
[How RAG Works]
When you ask a question, RAG retrieves relevant information from an external knowledge source. The retrieved information is then provided to the AI model, which uses it as context to generate a response.
[Vector Databases]
RAG systems often use vector databases to store information as numerical representations called vectors. This enables semantic search, allowing systems to find information based on meaning and similarity rather than only exact keywords.
[Simple Example]
Imagine asking an AI about your company’s policies. RAG can retrieve relevant information from your company’s documents and provide it to the AI, allowing it to answer based on that information.
[The Key Idea]
RAG combines retrieval and generation. It first retrieves relevant information from external sources and then provides that information as context to an AI model, which generates the final response.

What is an AI Vector Store and how does it work?
A vector store is a database that stores information as mathematical representations called vectors, allowing AI systems to find semantically similar content instead of matching only exact words.
———————————————————————
[Example]
A company has a document containing its return policy: “Customers can return products within 30 days.” This information is converted into a mathematical representation called a vector and stored in a vector store.
A customer asks: “Can I return these shoes after 20 days?” The question is converted into a vector that represents its meaning rather than relying only on the exact words used.
The vector store compares the question’s vector with the stored vectors and finds the return policy because it has a similar meaning, even though the wording is different.
The relevant return policy is retrieved from the vector store and provided to the AI model. The AI now has the specific information it needs to answer the customer’s question accurately.
The AI uses the retrieved information to generate a response: “Yes, you can return the shoes after 20 days because our return policy allows returns within 30 days.”
