OppenheimerGPT – use Bard and ChatGPT side-by-side (macOS menubar app)
I built this app over the weekend, let me know if you guys find it useful! * What is it?: Very simple to use. Type your prompt once, and app will mirror your prompt into both Bard and ChatGPT browser windows sitting side-by-side. Hit send! * Why did I built it? 1) I found myself consistently pasting the same question into both Bard and ChatGPT to get answers from each. This became even more frequent after ChatGPT disabled its internet browser plugin. 2) I wanted an elegant app that sits in macOS menubar, but I found no existing solutions. 3) I'm fascinated by the current AI race. I find it…
In plain words
OppenheimerGPT is a macOS menubar app that lets users query both Bard and ChatGPT simultaneously. Users type a prompt once, and the app automatically sends it to both AI services in side-by-side browser windows. Built for people who regularly compare responses from multiple AI models, it eliminates the need to manually copy and paste the same question into different interfaces. The app sits discretely in the macOS menubar for quick access.

I find it somewhat captivating to see which model does better for my question and see how each model is improving over time. Why is the app called OppenheimerGPT? :P Like many of you, I watched Oppenheimer movie over the weekend and drew numerous parallels between the movie and the ongoing AI race, hence the app's name.

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.

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…

I saw this [0] pretty cool thread by user revskill, and wanted a quicker way to search through it, but also to keep them all in one place so I can read them at my leisure whenever I get time. Right now is like 60 lines of Ruby using Nokogiri, but I will certainly look into it further down the line and improve the list. There's a cronjob checking the thread every 12 hours but I will eventually shut that down and it will become static after that. There are some really awesome blogs in there. I really recommend going through the list, it made my day. [0] "Could you share your personal blog…
