import { type ChatCompletionStreamOptions } from "https://deno.land/x/openai@v4.53.2/resources/chat/mod.ts";
Options for streaming response. Only set this when you set stream: true.
Properties
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.
