Hi there HN community. I'm excited to show my personal project -- an open-source code and hardware approach that connects my 1980's TRS-80 Model III computer to an OpenAI server. The TRS-80 can hold a chat session with OpenAI, and it's all very retro feeling. There were challenges along the way, as the approach to interfacing between ancient hardware and modern software interface wasn't immediately available. Please see https://github.com/druid77/trs-gpt for all the details, and let me know if you have any ideas for improvements. For example, adding support for voice.

What's under the hood: - Real-time messaging powered by Firebase - Buddy lists, groups & online presence - Away messages with auto-reply (and the classic %n, %d, %t variables) - Buddy icons & editable profiles - Group chat rooms - The actual AIM sounds - Full Windows 98 desktop UI — taskbar, desktop icons, start menu, the works. If you have any suggestions or feedback I would greatly appreciate hearing it. There's still more work to be done with it, but it's been a labor of love. Right now every user that logs on is automatically put on to your Buddy list. I thought this would be a great way…

Hey HN, I am proud to show you guys that I have built an open source alternative to Azure OpenAI services. Azure OpenAI services was born out of companies needing enhanced security and access control for using different GPT models. I want to build an OSS version of Azure OpenAI services that people could self host in their own infrastructure. "How can I track LLM spend per API key?" "Can I create a development OpenAI API key with limited access for Bob?" "Can I see my LLM spend breakdown by models and endpoints?" "Can I create 100 OpenAI API keys that my students could use in a classroom…

Hello HN, I’ve always loved building frontend-only apps—those you can prototype over a weekend, host for free on GitHub Pages, and scale to millions of users. Unfortunately, AI-enabled apps complicate things, as exposing your OpenAI key to the world is obviously a no-go. This also means mobile developers often have to run their own servers. That’s why I built ServerlessAI, an API gateway that lets you securely call multiple AI providers directly from client side using OpenAI-compatible APIs. You can authenticate users through any identity provider, like Google or Apple, and set per-user…

Admittedly I work on this, but I anthropic's decision to finally embrace http, auth (at least a little), and other RFCs that are coming out is just great. With OpenAI behind it too, this ecosystem will be built around projects like this. Not saying it's MCP or not, but it'll be one of them
