Cost Per Token

The price charged for processing each token of input or output.

E

Embeddings

Numerical representations that capture the meaning of text for AI processing.

F

Fine-Tuning

Additional training of an AI model on specific data to customize its behavior.

Few-Shot Prompting

Providing a few examples in your prompt to guide AI behavior.

H

Hallucination

When an AI model generates false or made-up information that sounds plausible.

I

Inference

The process of using a trained AI model to generate responses or predictions.

L

Large Language Model (LLM)

An AI system trained on massive text data to understand and generate human language.

Latency

The time delay between sending a request and receiving the first part of a response.

M

Multimodal

P

Prompt

The input text you provide to an AI model to get a response.

R

A technique that enhances AI responses by retrieving relevant information from external sources.

Rate Limit

Restrictions on how many AI requests you can make in a given time period.

S

Streaming

Displaying AI responses word by word as they're generated rather than waiting for completion.

System Prompt

Special instructions that set an AI's behavior, role, or personality for a conversation.

T

Token

The basic unit of text that AI models process, typically a word or word fragment.

Temperature

A setting that controls how random or creative an AI model's responses are.

Transformer

The neural network architecture that powers modern large language models.

Z
