TRS-GPT – ChatGPT client/server for the TRS-80

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.

In plain words

TRS-GPT is an open-source client-server system that enables a 1980s TRS-80 Model III computer to conduct chat sessions with OpenAI's servers. The project bridges vintage hardware and modern AI through custom code and hardware interfaces, allowing retro computing enthusiasts to interact with ChatGPT on classic equipment. The software and schematics are available on GitHub, with potential for future enhancements like voice support.

I trained a 125M model to autocomplete piano on-device▲598
I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Needle2: 14MB agentic LLM for phones, wearables, smart home and robots▲537
Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

LLMs can generate valid JSON 100% of the time▲854
Outlines is a Python library that focuses on text generation with large language models. Brandon and I are not LLM experts and started the project a few months ago because we wanted to understand better how the generation process works. Our original background is probabilistic, relational and symbolic programming. Recently we came up with a fast way to generate text that matches a regex (https://blog.normalcomputing.ai/posts/2023-07-27-regex-guide...). The basic idea is simple: regular expressions have an equivalent Deterministic-Finite Automaton (DFA) representation. We…
