回應格式
GPT 6 Astra 大型語言模型傳回與 OpenAI 相容的生成回應。設定 stream: true 時,回應為伺服器傳送事件(SSE);設定 stream: false 時,回應為單一 JSON 物件。

最佳實務
- 維持訊息結構: 使用
messages[] 傳遞對話歷程,不要將上下文合併成單一提示詞。
- 將檔案與圖片附加至訊息: 將
image_url 與 file 內容部分放入引入對應檔案或圖片的訊息內。
- 使用 SSE 解析: 附加
choices[0].delta.content 以逐步顯示內容,並將 data: [DONE] 視為成功完成。
- 僅傳送支援的輸入: 文字、圖片與檔案內容部分應符合所選模型的支援範圍。
- 在本機儲存請求狀態: 區塊包含生成回應的
id,但用戶端仍應透過目前作用中請求的狀態,將區塊分派至對應的處理流程。
