Hey everyone, this is Christina from

OpenAI. Welcome to Agent Builder 101.

Agent Builder is a new visual tool for

building AI workflows. You connect nodes

and create agents without writing any

code. So you can start from templates or

build your own from scratch. And it also

comes with built-in eval so you can test

and understand how your agents perform.

When you're ready, you can export the

workflow as code or drop it straight

into your product. Basically, it's your

all-in-one space to design, test, and

launch AI agents visually and fast. So

today we're going to show you how to

build your first agentic workflow, a

helpful travel agent that will help you

either build an itinerary or look up

flight information. So, we're starting

here in the OpenAI platform.

Every workflow starts with a start node

where you can set input variables or

state variables. And today for the

travel agent, the defaults are great.

Next, I'll connect a classifier agent.

I'm going to be building a specialized

itinerary agent in addition to a

specialized flight agent. And so, I want

to first determine which agent I should

route to. So, I'll call this classifier.

So, you are a helpful travel assistant

for classifying whether a message is

about an itinerary or a flight.

And here I'll specify the output format

as JSON. And I'll add a property called

classification

which will have two options either

flight info or itinerary.

Great.

Next, I'll add in an if else node um to

branch based off of the classification.

So if

put pars.classification classification

is flight info then we want to branch to

the flight agent and otherwise we want

to branch into the um the itinerary

agent. So from the flight agent we'll

create a new node and we'll call this

flight agent.

You are a travel assistant.

always recommend a specific flight to go

to.

Use airport codes.

And here I'll also give it access to web

search so I can have the most up-to-date

information about flights.

Great. For the itinerary agent, I'll

build um an itinerary agent with a new

agent node.

You are a travel assistant.

So build a concise

itinerary.

Great. I think that's everything we need

to get started with our travel agent. So

here in run preview, I'll ask it what

should I do in a day in Tokyo.

And I can see the message going through

the workflow that we just created. going

through the classifier agent, deciding

which category it should go to, seeing

that I asked about an itinerary, and

then passing it on to the itinerary

agent, whereas come up with a concise

one-day itinerary for Tokyo. Looks like

a great day. Now, for the flight agent

I actually want a richer experience for

showing flight information instead of

just plain text. And so, I can do that

by going and building a widget in our

widget studio. Here I've actually

already designed um a widget for showing

flight information to go from one

location to the next with um all the

details about the flight. So I can just

click download um to download this

entire template and then bring that

directly to the agent um that we just

created here. I'll add it in as the

widgets output format. I'll upload this

flight widget that we just pulled.

Preview it. Everything looks great. And

I actually want this to be a bit more

customized. Um, and so I will tell it to

choose a background color

creatively

based on the destination.

And I'll also ask it to include time

zones A.M. or PM.

Great. Let's test it out.

SFO to Tokyo on October 7th.

So here again, we see it moving through

the classifier agent um determining

whether I'm asking about um a flight or

an itinerary, deciding that I'm asking

about a flight agent um or deciding that

I'm asking about a flight, searching the

web, finding a flight for me, and then

showing it to me in this rich

interactive way. In this case, it's

decided that yellow is the color of

Tokyo. Um, and so showed that as the

background color.

Great. So I've now built an agent that

I'm happy with and I can publish it

directly. Let's call it travel agent

here.

And I now have a fully deployed agent

that is ready to go. Um, I can either

use the agents SDK. And here you can see

that this is quite a bit of code um for

me to manage myself

or I can simply take this workflow ID

and put it in my product directly using

jacket. So that's all. Hope that was

helpful and please leave any feedback in
