Editing Chuk Chat Concepts and Terms

= Chuk Chat Concepts and Terms =

This page explains common terms in simple language.

== Model ==
An AI model is the "brain" that generates answers.
Different models have different strengths, speed, and cost.

== Provider ==
A provider is the infrastructure service running a model.
The same model family can be available from multiple providers.

== OpenRouter ==
OpenRouter is the routing layer used by Chuk Chat to access multiple open-weight model providers.

== Token ==
A token is a small piece of text used to measure AI usage.
Both your prompt and the AI response use tokens.

== Credit ==
Credits are your usage balance.
More tokens usually means more credits consumed.

== Context window ==
The context window is how much text the model can consider at once.
Long chats or large attachments use more context.

== Streaming ==
Streaming means the response appears piece by piece in real time instead of all at once.

== System prompt ==
A system prompt is a hidden instruction that sets behavior and tone for the model.

== ZDR (Zero Data Retention) ==
ZDR means providers commit not to retain your request data for training/long-term storage.
Chuk Chat applies provider filtering for this.

== End-to-end encrypted chat storage ==
Your chat content is encrypted before storage. Without your password, old encrypted chats cannot be recovered.
