Tambo Add A Cursor style assistant for React apps (OSS, self-hosted)
Hi HN-- Tambo is a React SDK that lets your app render and control UI components based on natural language input. We are hooked on Cursor and want all our apps (Stripe, Vercel, GitHub) to have the same experience. I should be able to type `update env key` and get a UI to add it. Tambo lets an AI assistant render or update the state of registered React components. It can fetch context via MCP (Model Context Protocol) or client-side fetches (similar to OpenAI tool calls). The SDK handles streaming messages and prop updates, maintains thread history, and passes context across turns. It’s BYOM…
In plain words
Tambo is an open-source React SDK that enables applications to render and control UI components through natural language input. It allows developers to register React components that an AI assistant can display or update based on user requests. The SDK supports context fetching via Model Context Protocol or client-side requests, handles streaming responses, maintains conversation history, and works with Next.js, Remix, Vite, and React Native. It's designed for developers building AI-powered interfaces who want to bring Cursor-like functionality to their own applications.

If you’re building a “Cursor for X” (spreadsheets, video, design, etc.), check it out. Yesterday, we went 100% open source.

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 built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript.
