(JavaScript) Automatic JS AI Tool Function Calling using Chilkat within the JavaScript

See more AI Examples

• Tool function implementations are in JavaScript.
• The JavaScript also provides a tool registry and permissions.
• The JavaScript runs embedded within your application using Chilkat.Js.
• Tool calls are handled entirely within Chilkat. Your application does not need to manually check for function calls in the AI response. Internal to the Ask function, Chilkat will handle function calls by calling your registered JavaScript tools and will send results back to the AI model until the final response is received.

Note: This example requires Chilkat v11.4.0 or greater.

// If we were to set allowAllKeyword = true, then we could

// 
// Example.toolPermissions = [
// 	  {
// 	    name: "all",
// 	    perm: "sandbox",
// 	  }

// The provider can be "openai", "google", "claude", "grok", "mistral", "custom", etc.
ai.Provider = "openai";
// Use your provider's API key.
ai.ApiKey = "MY_API_KEY";
// Choose a model.

// Tool function calling must always occur within a conversation.

// Provide inputs
ai.InputAddText("What is my horoscope? I am an Aquarius.");

// Send inputs, tool functions, etc. and ask for a "text" response.
// If the AI responds with tool calls, Chilkat automatically handles them by calling your JavaScript
// tool functions as directed by the AI, and sending results back to the AI until the final
// response is received.
