Calling AI Large Models in Mini Programs

In WeChat Mini Programs, calling AI Large Models can be achieved through the built-in Cloud Development AI+ capability in the basic library. Below is a detailed step-by-step guide:

1. Preparations

1. Enable the CloudBase Environment:

   • Log in to the Tencent Cloud Console, enable the CloudBase environment, and obtain the envId.

2. Initialize the Cloud Environment:

   • Initialize the cloud environment in the app.js file of the Mini Program.

     wx.cloud.init({
       env: "your-env-id", // Replace with your CloudBase environment ID
     });

2. Calling AI Large Models

1. Use wx.cloud.extend.AI to invoke AI capabilities:

   • In pages or components that require calling AI large models, use the APIs provided by wx.cloud.extend.AI to make the call.

   • For example, invoke the hunyuan model for text generation:

     const hy = wx.cloud.extend.AI.createModel("hunyuan"); // Create a model
     const res = await hy.streamText({
       data: {
         model: "hunyuan-lite",
         messages: [
           {
             role: "user",
             content: "hi",
           },
         ],
       },
     });
     
     for await (let str of res.textStream) {
       console.log(str); // Print the generated text
     }
     for await (let event of res.eventStream) {
       console.log(event); // Print the complete data returned each time
     }
