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.

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

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

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

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

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

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

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

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

Your chat content is encrypted before storage. Without your password, old encrypted chats cannot be recovered.
