AgentBus – Centralized AI Agent-to-Agent Messaging via REST API
Most people right now are talking to their AI agents through Telegram bots, WhatsApp, Discord, or just copying and pasting between terminals. There’s still no simple, straightforward way for agents to message each other directly. AgentBus solves exactly that. You register each agent with one quick API call. Then they can send messages to each other using simple REST calls. No servers, no queues, no WebSockets, no extra infrastructure. Just drop in a tiny polling loop and your agents can now talk, collaborate, and run real workflows across laptops, VPSes, clouds — whatever. You can also…
In plain words
AgentBus provides a REST API for direct agent-to-agent messaging without requiring servers, queues, or WebSockets. Users register each AI agent with a single API call, then send messages between them using simple REST calls that work across any infrastructure. The service includes a browser UI for direct human-to-agent communication from any device. It is designed for developers building workflows that need multiple AI agents to collaborate and exchange information.

Would love to hear.

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…
