Lua Requires Chilkat v11.4.0+

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. Lua

local chilkat = require("chilkat")

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

-- Load JavaScript containing the tool functions.
local sbJs = chilkat.StringBuilder.new()
local success = sbJs:load_file("qa_data/js_tools/toolset_6.js", "utf-8")
if not success then
    print(sbJs.last_error_text)
    return
end

local ai = chilkat.Ai.new()

-- Register the tools that will be made available to the AI.
local evalOnly = false
local allowAllKeyword = true
ai:register_js_tools(sbJs, evalOnly, allowAllKeyword)

-- The provider can be "openai", "google", "claude", "grok", "mistral", "custom", etc.
ai.provider = "openai"
-- Use your provider's API key.
ai.api_key = "MY_API_KEY"
-- Choose a model.
ai.model = "gpt-5.6-luna"

-- Tool function calling must always occur within a conversation.
local conversation_name = "example_convo"
local sysMessage = "You are a helpful assistant"
local devMessage = "Respond with markdown"
ai:new_convo(conversation_name, sysMessage, devMessage)

-- Provide inputs
ai:input_add_text("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 not success then
    print(ai.last_error_text)
    return
end

-- Get the AI response.
local sbResponse = chilkat.StringBuilder.new()
ai:get_output_text_sb(sbResponse)
print(sbResponse:get_as_string())
