Open-source code search with OpenAI's function calling

We're excited to share a tool we've been working on called gpt-code-search. It allows you to search any codebase using natural language locally on your machine. We leverage OpenAI's GPT-4 and function calling to retrieve, search, and answer queries about your code. All you need to do is to install the package with `pip install gpt-code-search`, set up your `OPENAI_API_KEY` as an environment variable, and start asking questions with `gpt-code-search query `. E.g. You can ask questions like "How do I use the analytics module?" or "Document all the API routes related to authentication." This is…

Open-source code search with OpenAI's function calling launched on June 29, 2023 with 19 votes, #1,570 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

gpt-code-search is an open-source tool that lets developers search their codebases using natural language queries. It runs locally and uses OpenAI's GPT-4 with function calling to retrieve information and answer questions about code. Users install it via pip, set an API key, and ask questions like "How do I use the analytics module?" or "Document all API routes related to authentication." The tool handles function calling automatically without requiring manual implementation.

    Hi HN, Today we’re launching GPT-4 answers on Phind.com, a developer-focused search engine that uses generative AI to browse the web and answer technical questions, complete with code examples and detailed explanations. Unlike vanilla GPT-4, Phind feeds in relevant websites and technical documentation, reducing the model’s hallucination and keeping it up-to-date. To use it, simply enable the “Expert” toggle before doing a search. GPT-4 is making a night-and-day difference in terms of answer quality. For a question like “How can I RLHF a LLaMa model”, Phind in Expert mode delivers a…

    Hey 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…
