如何簡單地為使用 watsonx 的應用程式設定所有「採樣參數」或「生成參數」？

介紹

訪問 watsonx.ai LLM 的使用者經常遇到的一個問題是「我們如何設定採樣參數？」 !

其實很簡單。

採樣參數（或產生參數）

• 存取您的 watsonx.ai 實例。

• 點選「開啟提示實驗室」。進入提示實驗室後，在任一標籤中，按一下參數圖示（如圖所示最右側的圖示）。

您可以更改設定的LLM（之前使用的或預設設定的）。

• 開啟參數對話框後，可以依需求進行設定。

• 設定參數後，在同一組工具的圖示上選擇「查看程式碼>」。

介面將提供3種參數的程式碼嵌入實作； Curl、Node.js 和 Python 如下範例。

curl "https://us-south.ml.cloud.ibm.com/ml/v1/text/generation?version=2023-05-29" \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json' \
  -H "Authorization: Bearer ${YOUR_ACCESS_TOKEN}" \
  -d '{

開發者唯一應該調整的資訊是存取權杖。

瞧？

結論

watsonx.ai 平台讓應用程式開發人員可以非常輕鬆地調整 LLM 採樣參數集。
