To achieve this the context engine holds a `ContextBuilder` object that takes query results from the knowledge base and returns a `Context` object. The context builder also considers the `max_context_tokens` budget given to it and builds the most relevant context that not exceeds the token budget."

To achieve this the context engine holds a `ContextBuilder` object that takes query results from the knowledge base and returns a `Context` object. The `ContextEngine`'s default behavior is to use a `StuffingContextBuilder`, which simply stacks retrieved document chunks in a JSON-like manner, hard limiting by the number of chunks that fit the `max_context_tokens` budget. More complex behaviors can be achieved by providing a custom `ContextBuilder` class."
