Token
The basic unit of text that AI models process. Roughly, 1 token equals 4 characters or 0.75 words in English.
Real-World Example:
The sentence 'AI is transforming business' contains approximately 5 tokens. LLMs have token limits for input and output.
Related Terms:
Temperature
A parameter that controls the randomness of AI model outputs. Lower values (0-0.3) produce more focused, deterministic responses; higher values (0.7-1.0) produce more creative, varied outputs.

Use low temperature (0.2) for factual tasks like data extraction, and higher temperature (0.8) for creative writing.
Related Terms:
Tool Use / Function Calling
The ability of an AI model to recognize when it needs external information or tools and generate the necessary commands to use them (like searching the web or using a calculator).
Real-World Example:
When asked for current weather, an AI 'calls' a weather tool to get real-time data instead of relying on its training data.
Related Terms:
Text-to-Image
A type of Generative AI that creates visual art, photos, or diagrams based on a written description.
Real-World Example:
Typing 'A futuristic city in the style of Van Gogh' into Midjourney to get a unique AI-generated image.
