            If set, an additional chunk will be streamed before the `data:
            [DONE]` message. The `usage` field on this chunk shows the token
            usage statistics for the entire request, and the `choices` field
            will always be an empty array. All other chunks will also include a
            `usage` field, but with a null value.
