Tysm, a Rust crate for using ChatGPT with Structured Outputs
Hi HN! This Christmas I made `tysm`, a rust crates which simplifies using ChatGPT with Structured Outputs. Essentially you just tell it the rust type you want the output to conform to, and it handles creating the JSON Schema, passing it to ChatGPT's chat-completions API, and deserializing the response. Structured Outputs are very useful because they guarantee that the response will conform to whatever type you expect. I'm already finding my crate very useful since I love using Structured Outputs but I hate writing JSON Schemas myself. Technical details for rust heads: To generate the JSON…

Typed OpenAI Chat Completions in Rust. Contribute to anchpop/tysm development by creating an account on GitHub.
The Typed Chat Completions feature is the most interesting part, so most of this readme will focus on that. A strongly-typed Rust client for OpenAI's ChatGPT API that enforces type-safe responses using Structured Outputs . use tysm :: chat_completions :: ChatClient ; /// We want names separated into `first` and `last`. # [ derive ( serde :: Deserialize , schemars :: JsonSchema ) ] struct Name { first : String , last : String , } async fn get_president_name ( ) { // Create a client. // `from_env` will look for an API key under the environment // variable "OPENAI_API_KEY" // It will also look inside `.env` if such a file exists. let client = ChatClient :: from_env ( "gpt-4o" ) . unwrap ( ) ;…from github.com

Structured output from LLMs without reprompting2023 · automorphic.ai · ▲174Built a tool for transforming unstructured data into structured outputs using language models (with 100% adherence). If you're facing problems getting GPT to adhere to a schema (JSON, XML, etc.) or regex, need to bulk process some unstructured data, or generate synthetic data, check it out. We run our own tuned model (you can self-host if you want), so, we're able to have incredibly fine grained control over text generation.

GPT-JSON – Structured and typehinted GPT responses in Python2023 · github.com · ▲174Hey HN, I've been using GPT a lot lately in some side projects around data generation and benchmarking. During the course of prompt tuning I ended up with a pretty complicated request: the value that I was looking for, an explanation, a criticism, etc. JSON was the most natural output format for this but results would often be broken, have wrong types, or contain missing fields. There's been some positive movement in this space, like with jsonformer (https://github.com/1rgs/jsonformer) the other day. But nothing that was plug and play with GPT. This library consolidates…

An opinionated and statically-typed TypeScript SDK generator2022 · easysdk.xyz · ▲81Hi Hacker News! My name is Sagar, I’m working on a startup called Speakeasy - we’re making all APIs self-service. The platform is currently in beta, but we’re independently launching this tool which you can use to generate language-idiomatic, statically-typed TS SDKs from any public OpenAPI schemas. We hope to continue iterating on this to give devs a way to easily generate high fidelity client SDKs for all the major languages. Inspiration for this product is from past experiences struggling with OpenAPI. I was originally optimistic about using the OpenAPI tools to build out our offering,…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
