Developer releases brAIn, a reactive node network for local models

The author has released brAIn, an open-source agent framework that replaces traditional polling loops with a reactive architecture running entirely on local models. Nodes operate as daemons on an embedded NATS pub/sub bus, invoking the model only when subscribed messages arrive rather than at fixed intervals.

• The system eliminates idle GPU usage by avoiding constant "anything to do?" queries, ensuring costs are zero between messages.
• An iteration budget per wake prevents confused models from spinning the GPU in infinite loops.
• Users can distribute heavy workloads across multiple machines, such as using a MacBook for monitoring and a PC with an RTX 4090 for processing.
• The framework includes a live dashboard, bridges for Telegram, WhatsApp, and Discord, and supports connecting to external coding CLIs like Claude or Codex.

This approach aims to solve the inefficiency of standard agent frameworks by ensuring computational resources are only consumed when actual work is required.
