Hermes Agent, from Nous Research, is a serious piece of software. It keeps a persistent memory, writes its own reusable skills, schedules its own jobs, and reaches you over Telegram, Discord, Slack, WhatsApp, Signal or email. The software is free and MIT licensed, and the optional Nous Portal gateway turns $20 into $22 of usage across two hundred or more models.
The trade is the same as with any self-hosted agent, with one addition. You run it, secure it and keep it running; there is no rich chat interface, no documents, no team. And by default the hosted Portal may use your prompts, inputs and outputs to train and evaluate its services, with a privacy mode you have to find and switch on.
Magai keeps the ideas that make Hermes interesting, memory across every model, scheduled tasks, agents, and puts them in a workspace you sign in to, with dozens of models included and one training rule that never needs a toggle.
