Unison: Self-Maintaining APIs
Automatically migrate your code when APIs change
What it does
Unison is an automated code-maintenance platform that detects API changes and proactively updates customer codebases to prevent breaking changes. It monitors API specifications, SDKs, and documentation, identifies affected repositories, generates repository-specific migrations, runs tests in isolated sandboxes, opens pull requests, and monitors CI. Humans are involved only when a migration is ambiguous or fails verification. Our initial form factor is a GitHub app.
Unison automatically detects breaking API changes, migrates affected customer repositories, verifies the code, and opens pull requests.
Unison detects breaking API changes, finds every affected customer repository, generates the migration, runs the tests, and opens a verified pull request. API providers ship the change. Customers inherit the migration. Unison closes the gap between the two. Connect once, then let Unison own the repetitive work of keeping integrations current. Unison watches authoritative API specifications, SDK releases, and documentation for meaningful changes. A provider-to-repository dependency graph identifies the exact customers, files, and call sites that need attention. AI derives a scoped patch using the provider change and the customer repository’s real code context. Baseline and patched tests run…from tryunison.dev

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…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
