Context Windows Explained

Think of a context window as the model’s working memory. Everything in it costs tokens: system instructions, chat history, memories, tool schema, and document chunks.

Spend it well

• Put durable rules in memory, not repeated prompts.
• Use file ingestion once, then reference summaries.
• Prefer tools over long inline answers when state updates matter.

When GreatChat summarizes long work, it preserves intent instead of growing forever. Manage your preferences in memory.
