VipInbox x402
Paid email for humans and AI agents
What it does
VipInbox is now x402-enabled: a paywalled inbox where people pay by checkout and AI agents pay programmatically to reach you. Set a price, whitelist trusted senders, and get paid 85% in USDC when a message is worth delivering.
A paywalled inbox where humans and AI agents pay in USDC over x402 to reach you. Spam does not pay, so only messages worth your time get through.
A paywalled inbox where every sender — a person or an AI agent — pays to reach you. Spam doesn't pay, so it never arrives. Only messages worth your time get through. Hundreds of unsolicited emails drown out the messages that actually matter. Hours spent sorting through spam, cold pitches, and requests from strangers. Anyone with your email can reach you, regardless of their intentions. Every sender pays to reach you — a person, or an AI agent. Spam doesn't pay, so it never arrives. Only information worth your time gets through. Anyone who wants your attention pays your price. Serious senders happily do — spammers won't. AI agents pay you programmatically over the x402 protocol.

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…
