Creating OpenAI Assistant that Summarizes Articles

Building custom GPT became much easier with OpenAI Assistant.

  1. Visit OpenAI Assistant and click the Create button.

  2. Enter the name of your assistant, e.g. Article Summary Bot.

  3. Enter the instruction for your assistant:

    Your role is to summarize articles in a clear and concise manner. Each summary should be no longer than 2-3 paragraphs, with each paragraph containing maximum 3-4 sentences. Use no more than 120 words in total. This format ensures that the summaries are digestible and retain the essential points of the original article.

    Adjust the instruction to your needs.

  4. Click the Add button next the Functions section and paste the JSON below:

    {
      "name": "fetch_article",
      "description": "It fetches the content of the article",
      "parameters": {
        "type": "object",
        "properties": {
          "url": {
            "type": "string",
            "description": "The URL of the article"
          },
          "__api__": {
            "type": "object",
            "value": {
              "url": "{url}",
              "headers": {
                "Content-Type": "text/html; charset=utf-8"
              }
            }
          }
        },
        "required": [
          "url"
        ]
      }
    }
    

    This function uses the url parameter to fetch the website content. Check How to Use API Function Calling Using OpenAI Assistant for more details.

    * Note that the __api__ parameter is a special parameter supported by PlugBear.

  5. Click the Save button to create your assistant.
