Hey HN, I’ve built Open Codex, a fully local, open-source alternative to OpenAI’s Codex CLI. My initial plan was to fork their project and extend it. I even started doing that. But it turned out their code has several leaky abstractions, which made it hard to override core behavior cleanly. Shortly after, OpenAI introduced breaking changes. Maintaining my customizations on top became increasingly difficult. So I rewrote the whole thing from scratch using Python. My version is designed to support local LLMs. Right now, it only works with phi-4-mini (GGUF) via…

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…

api2ai parses OpenAPI Spec to generate an agent that can make API calls. For context, I recently need to explore a handful of API suites and thought LLMs can help expedite this process. After some digging, I found OpenAPI Specs are perfect fit for function calling. Based on a text prompt, api2ai can select the right endpoint and properly parse request params and make api calls. It also handles authentication, currently it supports basic auth, api keys, and bearer token schemes. The tool has helped me explore and see APIs in action without a deep dive into the docs or using postman. It’s open…
