CopilotKit – a hackable OSS copilot for any react app
CopilotKit is a typescript library for adding a hackable copilot to any react app. You can let the copilot interact with your app via plain typescript closures, and give it (explicit) read access to app data. An example user interaction could look like: - "Which of these travel destinations has a rich architecture history?" - [Copilot answers] - "Great. Add these to my august trip folder, except the ones where it's typically rainy then" - [Added] Recursive agent integration (via Langchain) is in the works - if you have ideas I'd love to hear them here or on the discord.
In plain words
CopilotKit is an open-source TypeScript library that adds an AI copilot to React applications. It allows the copilot to interact with apps through TypeScript functions and access app data with explicit permissions. Users can ask the copilot questions about their data and request actions like organizing items based on multiple criteria. The library is designed for developers building React applications who want to integrate conversational AI capabilities directly into their user interface.

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…
