[NEW] Structured Prompt Outputs & Variable Pathing

Key Takeaways

voice loow just got more powerful we've released two features that let you build AI agents without needing to create a gazillion variables and ones that make sure open AI llms return data in a specific Json format rather than me telling you about these features let me show you first up structured outputs structured outputs let you force an llm to return data in a specific format for example if you're building a sentiment classifier you could force your AI agent to return the emotion V Texas expressing and how sure it is of that fact so let's try using them now I'm going to add a set step to my canvas logic and a set and I have already built myself a nice little prompt so I'm going to set this using a prompt and the prompt is going to be get City info so let me show you some info about this prompt I'm literally just saying you're an AI agent get City from your knowledge and I'm passing in a city at no point in my prompt am I actually telling it what output I'm expecting but if I open settings you can see I'm using GPT 40 structured outputs are supported in GPT 40 and full om many at release and we have a new Option here Json output that's enabled if I give it a click you can see here that we have defined an output format now this output format follows a subset of open AI syntax and it supports these types but heads up it doesn't support nesting you can learn more at this link so we have defined an output that that has two properties we're expecting a city name which is a string and a population which is a number so now we set this output format we can then use that in other steps so let me close out of here and I'm going to make sure that I'm setting a variable so City info to the output of this prompt awesome so now we have an output stored in a variable but until today you need to create multiple variables one for each property that's being outputed you case city name and population but no more thanks to a feature called variable pathing Nina built it and she's going to tell you a bit about it well actually shout out to Pedro who build this feature as well so now that you have the city info stored in a single variable you can base your further Logic on its properties I'm going to add a condition of Tye business logic here and I want to check if the population of the city returned in City info is bigger than 5 million so I'm hitting tab after City do population enter is greater than let's say 5 million 1 2 three six okay if it is I'm going to say whoa city info. city is a big city or otherwise seems like a small City to me okay now that we've built it let's try it out together I'm going to hit start and it prompts me for a city and I would much rather be in Tokyo right now so I'm going to say Tokyo and as you can see it says it's a big city and indeed the population of Tokyo is more than 5 million that was possible thanks to the structured output returning all the city info to this city info variable and US reading the de population property of it and comparing it to the number that we set now I'm going to try to reset this test and try Toronto and indeed it seems like a small city which we already knew pretty cool right oh and Jac has one more thing to show you thanks CA I want to show you that structured outputs support more than just prompts for example I have this API that returns a bunch of posts from my website all the posts are in laddin because uh reasons instead of capturing each piece of data about a post manually it's title ID and body I can just store the entire object about a post in a variable using variable pathing then my AI agent can tell me all about the latest post on my website can even do a little bit of sentiment analysis to determine how I was feeling in that in this case it was a completely neutral story with variable paing you no longer need to create multiple variables to store properties about the same piece of information for example a user and with structured outputs you can be sure that your calls to llms are returning the data that you would expect good Lu the building and let us know in the comments down below what you plan to use these new beaches for
