    4,096 max output tokens can only include 28,224 tokens in the context before
    truncation occurs.

    Clients can configure truncation behavior to truncate with a lower max token
    limit, which is an effective way to control token usage and cost.

    Truncation will reduce the number of cached tokens on the next turn (busting the
    cache), since messages are dropped from the beginning of the context. However,
    clients can also configure truncation to retain messages up to a fraction of the
    maximum context size, which will reduce the need for future truncations and thus
    improve the cache rate.

    Truncation can be disabled entirely, which means the server will never truncate
    but would instead return an error if the conversation exceeds the model's input
    token limit.
