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. Objective-C

#import <CkoStringBuilder.h>
#import <CkoAi.h>
#import <NSString.h>

BOOL success = NO;

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

//  Load JavaScript containing the tool functions.
CkoStringBuilder *sbJs = [[CkoStringBuilder alloc] init];
success = [sbJs LoadFile: @"qa_data/js_tools/toolset_6.js" charset: @"utf-8"];
if (success == NO) {
    NSLog(@"%@",sbJs.LastErrorText);
    return;
}

CkoAi *ai = [[CkoAi alloc] init];

//  Register the tools that will be made available to the AI.
BOOL evalOnly = NO;
BOOL allowAllKeyword = YES;
[ai RegisterJsTools: sbJs evalOnly: evalOnly allowAllKeyword: 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.
NSString *conversation_name = @"example_convo";
NSString *sysMessage = @"You are a helpful assistant";
NSString *devMessage = @"Respond with markdown";
[ai NewConvo: conversation_name sysMsg: sysMessage devMsg: 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 == NO) {
    NSLog(@"%@",ai.LastErrorText);
    return;
}

//  Get the AI response.
CkoStringBuilder *sbResponse = [[CkoStringBuilder alloc] init];
[ai GetOutputTextSb: sbResponse];
NSLog(@"%@",[sbResponse GetAsString]);
