Integration Dasha with OpenAI GPT

Dasha Scripting Language allows you to integrate GPT flow with common dialog flow using #answerWithGPT function

How does it works?

When you want to response to the user with GPT you can call

var result = #answerWithGPT(`Your prompt`, interruptible:true, gptOptions: {
            model:"openai/gpt-4",
            openai_apikey: "YOUR APIKEY"
        }, sayOptions: {
            interruptDelay: 1.0
        });

Where model:

openai/gpt-4
openai/gpt-3.5-turbo
any other OpenAI model using prefix openai/

openai_apikey - your OpenAI APIKEY

interruptible & interruptDelay - allows user to interrupt answer process if user is speaking for interruptDelay seconds

the result will contain information about what happened:

result.interrupted will be true, if user has interrupted the system
result.functionCalled will be true, if gpt requested a function call (see docs below)

GPT Functions

Using GPT functions with DSL can give you a powerfull conversation model.

When you writing any function with JavaDoc like

context {
    output customerName: string? = null;
    output customerPhone: string? = null;
}
/**
*    Store collected customer information such as name and phone number
*    @param customerName customer name provided
*    @param customerPhone customer phone provided
*    @return true
*/
function storeCustomerInfo(customerName: string?, customerPhone: string?): boolean {
    set $this.customerName = $this.customerName ?? customerName;
    set $this.customerPhone = $this.customerPhone ?? customerPhone;
    return true;
}

Our Dialog Engine passes information about a function storeCustomerInfo and it's description to the OpenAI inside a request. And this function will be called when user provides any information described in arguments. Result of function call will be passed to GPT on next call of #answerWithGPT

/**
*  Get price of fruit in USD
*  @param fruit name of fruit
*  @returns price in USD or `No such fruit` if fruit is not found
*/
function getFruitPrice(fruit: string) : number|string {
    if (fruit == "apples") {
      return 6.29;
    }
    if (fruit == "oranges") {
      return 1.49;
    }
    return "No such fruit";
}

Examples

Full DSL example

context
{
    input endpoint: string;
}


/**
*  Get price of fruit in USD
*  @param fruit name of fruit
*  @returns price in USD or `No such fruit` if fruit is not found
*/
function getFruitPrice(fruit: string) : number|string {
    if (fruit == "apples") {
      return 6.29;
    }
    if (fruit == "oranges") {
      return 1.49;
    }
    return "No such fruit";
}


start node root
{
    do
    {
        #connectSafe($endpoint);
        #sayText("Hi, this is Mary! How can I help you today?");
        wait *;
    } transitions {
        gpt: goto gpt on true;
    }
}


node gpt {
  do {
        // We will be here when user says something, or retry is required
        var a = #answerWithGPT(`Your name is Mary. 
        You are working in fruit seller contact center.
        You can only tell customer a price of requested fruit.
        If you have no price for fruit tell: We have no such fruit
        `, interruptible:true, gptOptions: {
            model:"openai/gpt-4"
        }, sayOptions: {
            interruptDelay: 1.0
        });
        // Call answerWithGPT one more time for passing result to the GPT
        if (a.functionCalled) {
            #log("Called a function, retry");
            goto retry;
        }
        wait *;
  }
  transitions {
      gpt: goto gpt on true;
      retry: goto gpt;
  }
}

digression @exit {
  conditions { on true tags: onclosed; }
  do {
    exit;
  }
}
