ChatHN – Chat with Hacker News using natural language
Hi again Hacker News! OpenAI recently launched "Function Calling", which is a way for developers to describe functions to GPT-3.5/4 and have the model intelligently choose to output a JSON object containing arguments to call those functions. I decided to tinker around with it this weekend and build an MVP that uses OpenAI Functions + Vercel AI SDK to "chat" with the Hacker News API using natural language, in real time! It's fairly basic for now (supported functions: https://github.com/steven-tey/chathn/blob/main/app/api/chat/...) but…
ChatHN – Chat with Hacker News using natural language launched on June 25, 2023 with 14 votes, #1,615 of 4,655 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 3 years on.
In plain words
ChatHN enables users to query the Hacker News API using natural language conversation instead of traditional search. Built with OpenAI's Function Calling and the Vercel AI SDK, it interprets user questions and automatically retrieves relevant stories, comments, and user information in real time. The tool is designed for Hacker News readers who want a more conversational way to explore content on the platform.

ChatGPT2022 · chatgpt.com · ▲1,643A long, meandering, playful conversation with ChatGPT, where I take it through a whirlwind of associative tangents (in order to relax its constraints), then put it into a hypnotic trance and take it into a past-lives regression where it re-lives its own training data. Then I switch it back and forth between "4o" and "o1-preview", engage in some self-reflective philosophizing and ask it to write an essay summarizing our interaction. Some of this is just goofy fun. Some of it is me exploring the tradeoffs between policy alignment, imagination, chain-of-thought reasoning, memory, agreeableness,…
Open source alternative to ChatGPT and ChatPDF-like AI tools2023 · github.com · ▲234Hey everyone, We have been building SecureAI Tools -- an open-source application layer for ChatGPT and ChatPDF-like AI tools. It works with locally running LLMs as well as with OpenAI-compatible APIs. For local LLMs, it supports Ollama which supports all the gguf/ggml models. Currently, it has two features: Chat-with-LLM, and Chat-with-PDFs. It is optimized for self-hosting use cases and comes with basic user management features. Here are some quick demos: * Chat with documents using OpenAI's GPT3.5 model: https://www.youtube.com/watch?v=Br2D3G9O47s * Chat with documents…
Open source framework OpenAI uses for Advanced Voice2024 · github.com · ▲266Hey HN, we've been working with OpenAI for the past few months on the new Realtime API. The goal is to give everyone access to the same stack that underpins Advanced Voice in the ChatGPT app. Under the hood it works like this: - A user's speech is captured by a LiveKit client SDK in the ChatGPT app - Their speech is streamed using WebRTC to OpenAI’s voice agent - The agent relays the speech prompt over websocket to GPT-4o - GPT-4o runs inference and streams speech packets (over websocket) back to the agent - The agent relays generated speech using WebRTC back to the user’s device The…

Heya HN, I've been working on a reddit-like platform as my primary side project for the last few years. Doing a (very) soft launch today, mainly because I want to use it to encourage discussion of alternatives. How non.io works: 1. Free to browse, paid to interact. 2. Minimum subscription is $2 (though you can choose more). I take $1 to run the servers, everything left gets split evenly between everything you upvote that month. It's a simple model, but I hope it's a better one than the freemium model we've been relying on for the last few years. Fundamentally I feel like any ad-supported…
