AI Ask with Multiple Tool Function Callbacks

See more AI Examples

This example demonstrates asking a two-part question that should cause the AI to respond with two tool call requests. VB.NET

Dim success As Boolean = False

' ----------------------------------------------------------------------------------
' The Javascript file loaded here is shown at the bottom of this page.
' -----------------------------------------------------------------------------------

' Load JavaScript containing the tool functions.
Dim sbJs As New Chilkat.StringBuilder
success = sbJs.LoadFile("qa_data/js_tools/toolset_6.js","utf-8")
If (success = False) Then
    Debug.WriteLine(sbJs.LastErrorText)
    Exit Sub
End If


Dim ai As New Chilkat.Ai

' Register the tools that will be made available to the AI.
Dim evalOnly As Boolean = False
Dim allowAllKeyword As Boolean = True
ai.RegisterJsTools(sbJs,evalOnly,allowAllKeyword)

' 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.
ai.Model = "gpt-5-mini"

' Tool function calling must always occur within a conversation.
Dim conversation_name As String = "example_convo"
Dim sysMessage As String = "You are a helpful assistant"
Dim devMessage As String = "Respond with markdown"
ai.NewConvo(conversation_name,sysMessage,devMessage)

' Provide inputs
ai.InputAddText("What is my horoscope? I am an Aquarius.  Also, what's the weather in Chicago?")

' 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.
success = ai.Ask("text")
If (success = False) Then
    Debug.WriteLine(ai.LastErrorText)
    Exit Sub
End If


' Get the AI response.
Dim sbResponse As New Chilkat.StringBuilder
ai.GetOutputTextSb(sbResponse)
Debug.WriteLine(sbResponse.GetAsString())
