Claude.vim – a different take on AI pair programming
I explored how I can use AI when writing software beyond code completion, and I didn't like any of the UX I saw (maybe except Cursor). Well, I do all my work in vim. Claude knows how to use vim! And... you can do anything(!) from vim. Turns out, embedding Claude in vim means you get a fully agentic AI pair programmer in <1000 LoC. (See the GitHub README for examples of what "fully agentic" means.) And if you have some semantic vim tools (jedi.vim, eclim, ...) set up, Claude could use them if instructed. Unlike CLIs, you can review Claude's changes, and keep the chat history. So an editor…
In plain words
Claude.vim integrates Claude AI directly into the Vim text editor, enabling agentic pair programming for software development. Built in less than 1,000 lines of code, it allows developers to leverage Claude's capabilities without leaving their editor while maintaining full control over changes and conversation history. The tool works with semantic Vim plugins like jedi.vim and eclim, letting Claude assist with complex programming tasks beyond simple code completion. It's designed for developers who prefer Vim as their primary workspace.

Unlike CLIs, you can review Claude's changes, and keep the chat history. So an editor interface is the killer feature for real work. Sonnet 3.5 won't take your programmer job yet. But it can make you a lot faster, even if you type very fast (especially its one-shot ability is amazing). The trick is not to give up thinking and stay in charge. Just let it do the grunt work. P.S. I literally never wrote anything in vimscript before claude.vim. Thankfully, Claude did 95% of the code grunt work for me, most of the time already self-hosted. P.P.S. Claude is on AWS Bedrock, chances are you can use it even in environments where sending code to random 3rd-party SaaS is a no-no.

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…

Many years ago, I made VJ softwares (to mix live visuals in clubs) for unexpected platforms like the Game Boy Advance, the Playstation 2 and the Raspberry Pi. This year, I’m back with a new web-app: Pikimov. Inspired by Photopea (a free Photoshop clone), I created this web-based motion design & video editor as an alternative to After Effects, to fill empty void. It's free, without signup, without cloud uploads (your files stay on your machine), and your projects are not used for AI models training.
