If this was you, then you've probably been pretty happy to see OpenAI function_call get released, I'm here to show you how you can get the most out of such powerful feature. Instead of writing prompts that turn strings into strings, we can write Pydantic objects and get Pydantic objects out of OpenAI.
In this talk we explore some model driven development. Where we go step by step with some examples on how to represent your problem as simple code so we can model, generate diagrams, and write prompts as code to save time and model complex data correctly, allow us to use the same best practices rather than having to invent new ones for how we manage prompts.

Thanks for having me on! this was my first publish speaking thing in like.. .5 years
Our pleasure! You did excellent!
Really great talk. Credible on the code but effortlessly natural in delivery. Hope to hear more from you, do you have a blog or other outputs?
I'm having so much fun playing with some of your insights. I had already built some interesting tools when functions first came out and twitter was showing how pydantic was the key to making it really usable. But this is such a great progression. Thanks!
@@philsheard832yeah I have a personal blog and int instructor docs.
Really enjoyed this. Thanks Jason!
Jason Lio is seriously next level, he brings so much in this video, can watch this 10 times.
hopefully watching it the 11th time you can spell his name properly
Awesome talk jasonliu ......really learned something new today.Thank you for sharing this
Thank you Jason. Phenomenal work and effort + you & your team.
This awesome! Thank you for sharing this!
I was at the conference in person -- this talk was a major highlight. Glad to see it again!
thanks for sharing!
I used decorators over my calls to allow for feedback loops ! Pydantic is a must 😊
Great talk. Such a useful workflow, thanks!
Thank you for your presentation
Wow, outstanding talk. I came in thinking a 15 minute talk on typing wouldn't be that interesting, but by the end I felt like this was the most well explained and immediately useful presentation on here.
Same here!
Thanks for the kind words would love any feedback on the docs or on the talk if you have any
@@jxnlcoawesome presentation. Where can I dive deeper into this for other models? I heavily use Pydantic today, but other models for work. You mention ask Marvin. What are the differences between that and Instructor?
This is something very different from all the other stuff out there!
Well this really helped me learn Pydantic🎉
Thank you :)
Engineers used to be expensive because they produced potentially infinite automation.
Today, they're expensive because they consume potentially infinite automation.
engineers are expensive because not everyone wants to deal with things that abstract and complex. I mean, engineers are close to create a machine that is smarter than them, which can make them obsolete, but still did it. which other profession is so true to it?
Such a smooth talk!!
Thank you
Great talk and content!
Incredible talk!
Great talk!
amazing job!
Respond only with a valid json and nothing else. MY AND MY FAMILY'S LIFE DEPEND UPON THIS!
Let us hope Roko's basilisk will look kindly upon us emotionally manipulating our poor LLMs
Validation with citation is very interesting. I did this using normal prompt engineering and hoped I’d get good results every time 😂
Nice one!

lol i JUST finished our pydantic based datamodels - it’s great, nice to see this, feels like `validation` lol
Makes me interested in using Rust for LLM interactions. Whether the LLM return is validated or not you’re forced to handle every case and thus will make more robust systems by design.
This has been growing on me.
Hi: thanks for the talk. Where can we find out more about instructor? (16:33) Oops, there it is one second later.
this is so good it hurts my feelings a little
TIL that you can copy text from youtube videos. very slick... and great talk Jason :)
jason here
Now this is good. This is going to be the way to actually integrate llm models with apps that goes beyond chatbots more reliable
thank you! let me know if you have any thoughts, available in the github issues etc or on twitter
How come instructor requests don't need async await for calling the APIs?
cause it just uses `create` vs `acreate`
This just seems to be wrapping a prompt into a python class or function. How is this any more reliable/reliant that just straight prompts/json, since what goes to OpenAI API's is still a prompt. Not sure what I am missing here, but I don't see this being that much more useful.
How is this different from langchain?
I don't want to install the whole rust toolchain to install pydantic on riscv.
I still don't understand how instructor works behind the scenes, for example if I want chapters from a youtube transcript how do I prompt it?
you might ask for a chapter with a title and body, and then ask for a list
class Chapter:
timestamp: int
title: str
summary: str
class VideoChapters:
chapters: List[Chapter]
response_model=VideoChapters
something. like this! i actually build youtubechapters dot app so there ya go

Ephesians 1:13 In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
Ephesians 1:14 Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
Ephesians 4:30 And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
Who is the speaker, where is he on Twitter?
jxnlco !
70M downloads a month...how many developers exist in the world ?
-- "AI will take software engineer job"
-- Software engineer: "Hold my beer."
This is great. I've been using openai to process survey data in begging mode "please respond with valid json"... try/except/loop
Anyone know:
1. If using pydantic, will we hit any issues with async calls?
2. Can we achieve structured, error-handled responses using langchain instead? Is that the way to go?
we'll run into issues of using async validators, but async don't be an issue otherwise

this "all you need" trend in the AI community is out of hand lol
True haha @@richcaputo2929
I don't get it. What's new about this? Has been part of langchain for a while now.
well who do you think introduced this to langchain ;)
@@jxnlco I see & apologize 😀 This has been fantastic. Loved the idea straightaway.
Are you on Twitter?
@@alivecoding4995 @jxnlco
haha yeah i was the reviewer on the langchain function calling PRS when it came out. but we do validation differently.
so basically typescript....... ?
Models have behavior. Type hints do not.
Base model has runtime type information. Typescript does not. You would need zod. Which lacks coloration of behavior.
And people say rustc is too complicated.
I wish that was more like a tutorial. It is really hard to follow.
I'll be making one coming out in a month or so!
if you want to integrate with legacy software, named pipes are your friends. thank me later
If I want so much of gibberish boilerplate with types i will use Java.
Or…. you could just use a statically typed language to begin with….
an llm is not statically typed.
@@jxnlco what I meant is have the LLM generate code in a typed language, and write the code that interprets the results in a typed language.
Whoever decided to make a fresh version of pydantic without backwards compatibility (breaking fastapi and everything else), you wasted so many human-hours, and made people remember what are virtual environments. 😡
great talk, but please stop using pydantic!
what do you suggest?
@@jxnlco haskell \s
To be honest, pydantic is so far ahead of other solutions like dataclasses and attrs that I have trouble arguing against them. But they come with their own typesystem and the authors have been known for causing drama in the python community.
@@jxnlco attrs
LMAO, I made something better than this tbh! I don't even want to go on to showcase it to you all, but it's way better than this. dude, I never thought this was a problem to all, lolz. well, I'll be releasing it too then ig. thanks for making this video!
How its called and where I can try it
@@xlagunaa okay, so basically i made it a private repo, well this is the idea ig i didn't explain it well back then lol, well, this is how it works, we get a json response, and i convert the json response into a class like object so now instead of accessing data like: response["user"]["name"], you can do it like response.user.name and this just makes ig the typing easier and the code more readable, i mean that's my preference tbh, but then it didn't really work that well, if u liked the concept then ig i'd give u the link to it.
Oh, this is on Python. Sorry, not interested.

i hate everything about what llms are doing to us, and the fact that a bunch of hangers-on blockchain type bros are just making as much bullshit as possible on top of them
