Nuanced – Help AI understand code structure, not just text
Hi HN! We built Nuanced (https://github.com/nuanced-dev/nuanced), an open-source Python library that makes AI coding tools smarter about code structure. The problem: current AI coding assistants see code as just text. They don't understand which functions call which, or how code components depend on each other. This is why they often suggest changes that break dependencies they should have known about. Nuanced solves this by generating call graphs that map these relationships. When you ask "What would break if I change this function?", instead of guessing, the AI can see…
In plain words
Nuanced is an open-source Python library that helps AI coding assistants understand code structure beyond plain text. It generates call graphs mapping which functions call which and how code components depend on each other, allowing AI tools to identify potential breaking changes when suggesting code modifications. Developers can analyze their Python modules, extract relationship data for specific functions, and incorporate this information into AI prompts or integrate it into coding tools.

Hi HN! We built Nuanced (https://github.com/nuanced-dev/nuanced), an open-source Python library that makes AI coding tools smarter about code structure. The problem: current AI coding assistants see code as just text. They don't understand which functions call which, or how code components depend on each other. This is why they often suggest changes that break dependencies they should have known about. Nuanced solves this by generating call graphs that map these relationships. When you ask "What would break if I change this function?", instead of guessing, the AI can see the actual dependencies. How it works: 1. Run `nuanced init .` to analyze a Python module in your codebase 2. Use `nuanced enrich app/file.py function_name` to get relationship data 3. Include this data in your AI prompts or integrate it into tools We're already working with teams building AI coding assistants and security review tools to integrate this capability. Our initial release supports Python with plans for JavaScript/TypeScript next. I'd love your feedback, especially if you're building dev tools that could benefit from better code structure understanding!

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…
