Prove Stateful Multi-Turn Conversation

See more AI Examples

This example is to prove that the 2nd request in a conversation is part of a stateful multi-turn conversation. The 2nd request asks for information provided in the 1st request. Swift

func chilkatTest() {
    var success: Bool = false

    //  This example assumes the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    let ai = CkoAi()!

    //  The provider can be "openai", "google", "claude", "deepseek", "xai", or "perplexity".
    //  Support for additional providers will be added in future versions of Chilkat.
    ai.provider = "google"

    //  Use your provider's API key.
    ai.apiKey = "MY_API_KEY"

    //  Choose a model.
    ai.model = "gemini-3.6-flash"

    //  Create a new conversation to be maintained locally in memory.
    //  If the conversation is the first to be created, it is also automatically selected.
    var systemMsg: String? = "You are a helpful assistant"
    var developerMsg: String? = ""
    var conversationName: String? = "test_conversation"
    ai.newConvo(name: conversationName, sysMsg: systemMsg, devMsg: developerMsg)

    //  -------------------------------------------------------------------------------------------
    //  Our first request will establish a secret that we'll ask for in the 2nd request.
    //  Add a text input.
    ai.inputAddText(text: "Please remember this: The word I'll ask for later is BlubberFish.  What's the word?")

    //  Ask the AI for text output.
    success = ai.ask(outputType: "text")
    if success == false {
        print("\(ai.lastErrorText!)")
        return
    }

    //  Note: The inputs accumulated through one or more calls to Input* methods are cleared when the Ask method returns with success.

    //  Get the text response.
    let sbResponse = CkoStringBuilder()!
    ai.getOutputTextSb(sb: sbResponse)
    print("\(sbResponse.getAsString()!)")
    print("----")

    //  Sample output:

    //  The word is **BlubberFish**.

    //  -------------------------------------------------------------------------------------------
    //  Let's ask for the word. If this is a stateful conversation, the AI should respond correctly.
    ai.inputAddText(text: "OK, I'm going to ask you again, what's the word?")
    success = ai.ask(outputType: "text")
    if success == false {
        print("\(ai.lastErrorText!)")
        return
    }

    //  Get the text response.
    sbResponse.clear()
    ai.getOutputTextSb(sb: sbResponse)
    print("\(sbResponse.getAsString()!)")

    //  Sample output:

    //  The word is **BlubberFish**.

    //  -------------------------------------------------------------------------------------------
    //  Look at the conversation so far...
    //  
    let json = CkoJsonObject()!
    ai.exportConvo(name: conversationName, json: json)
    json.emitCompact = false
    print("\(json.emit()!)")

    //  Note: The conversation transcript format exported and imported by Chilkat is always the OpenAI format,
    //  regardless of the AI provider.  (Chilkat translates the format from OpenAI to whatever is needed by the actual AI provider being used.)
