OpenAI Assistants API 🤯 Function Calling + Node.js 🚀 How to get started? AMAZING!! (Full Tutorial)

Key Takeaways

this is huge what if you can add function calling to your assistant's API what if you can integrate that in your nodejs application that's exactly what we're going to see today let's get [Music] started hi everyone I'm really excited to show you about assistance API with function calling in a node.js application I'm going to take you through step by step on how to run this and code yourself before going into that I regularly create videos in regards to artificial intellig so do subscribe and stay tuned coming to assistant API the first step is create your assistant that is data analyst next you're creating a thread third you're creating a message finally you're running the code with custom instructions I have already covered this in the previous video which I will link that in the description below so it basically contains assistant thread and then we create a message then we run it message is when the user asks question to the data analyst now we're going to run this code without fun function calling the question we going to ask the data analyst is what is the stock price of Apple that is the message now we're going to run this code in your terminal note function calling. JS you can see the status is queued now now the status got completed and we got the answer here assistant I'm sorry mvin praison but I don't have the capability to provide a real-time stock market data or updates Chad GPT doesn't have the capability to get the realtime stock price this is when the function calling comes in function calling is nothing but a function or a software or a tool which can be integrated with assistant API imagine you have a function which gets the stocks price in real time now we are going to see how we are going to integrate that with this application I'm going to use Yahoo finance to get the realtime stock price so it's npm install yaho iPhone Finance 2 and click enter going back to the code you are importing Yahoo finance from Yahoo finance 2 we going to create Asing function with get stock price and pausing the symbol as the parameter and it Returns the real-time stock price now we're going to integrate this function in assistant API using function calling to do that first we going to create tools list constant tools equals and then you're adding the list here you're mentioning type is function and the function name is get stock price that's what we defined previously then we are providing the parameters that is the symbol and symbol is the only required parameter now we're going to pause this tool when weate create an assistant so tools equals tools we have done two things one is creating a function called get stock price and then we created a tools list and added that to the assistants create function if you see the list of steps without function calling there are four steps but when you add function calling you're adding one more step which is requires action now we're going to add this in the code in the code while checking the status of the run here we mention completed there is one more status called required action I'm going to add that else if run status. status equals requires action then console.log requires action just for our reference then constant required actions equals run status. required action do submit tool outputs. tool calls this is where you retrieve your required actions and now we're going to print the required actions and now we're going to run the code in your terminal note function calling. Js first it get cued the status then here the status becomes requires action and you can see there's a Json called required action and we are printing the required action here the required action constant contains a function get stock price and the symbol AAPL so this symbol need to go into get stock price and we need to return that back to assistant API this Loop will keep on continuing until we return the stock price so I'm going to cancel this one and going back to the code I'm going to Define let tools output equals to a list then I'm going to Loop through this required action for constant action of required action opening the bracket constant function name equals action do function. name which you can see here the action. function. name next we going to get action. function. arguments that's where you'll have the symbol AAPL function arguments equals action do function. arguments now we're going to pass this Json because that is a Json output IF function name equals get stock price constant output equals await get stock price and passing the symbol next Tool output. Push tool call id action. id comma output colon json. stringify output now closing the brackets else console.log unknown function and closing the overall bracket now we got the tools output with the required stock price now we need to return that back to assistant API that is the final step the way we do it is await open ai. beta. threads. runs do submit tool outputs you're passing the thread ID run ID and the tools output this we can consider as the final fifth step that's it we checked if the status is requires action then we par the required action output check if the function is get stock price run the function and then we finally return the tools output back to submit tools output now we're going to run this code in your terminal node function calling. JS now the status got cued now we can see the status requires action then we are parsing this Json which contains this function and the parameter now our function is running which is yahooo finance and finally the status completed and we got a response here as a user we asked what is the stock price of Apple and the assistant replied the stock price of Apple is 1 8744 USD that's it as simple as that now you are able to integrate any function in your assistant API using function calling there is one more thing I want to tell you if you want me to present your work or your code like this do submit your code in the URL shown in the screen m.v n/s submit work I'm going to create more videos in regards to assistant API so stay tuned I hope you like this video do like share and subscribe and thanks for watching
