delta: Delta

A chat completion delta generated by streamed model responses.

    | null
    | "length"
    | "stop"
    | "function_call"
    | "tool_calls"
    | "content_filter"

The reason the model stopped generating tokens. This will be stop if the model hit a natural stop point or a provided stop sequence, length if the maximum number of tokens specified in the request was reached, content_filter if content was omitted due to a flag from our content filters, tool_calls if the model called a tool, or function_call (deprecated) if the model called a function.

index: number
