About Hermes Agent

Hermes Agent

Hermes Agent is presented as an agent that grows with the user. According to the page, it learns projects, auto-generates skills, and retains memory of how it solved problems. It can be reached through Hermes Desktop, the terminal, or messaging platforms such as Telegram, Discord, Slack, WhatsApp, Signal, and email. The page describes isolated subagents, natural-language scheduling for unattended tasks, web search and browser automation, vision, image generation, text-to-speech, and multi-model reasoning, with five sandboxing backends (local, Docker, SSH, Singularity, Modal). Conversations, memories, and skills persist between sessions. Hermes Agent is free and open source under the MIT license; model providers and optional hosted services have their own pricing, and users can bring their own provider or connect to Nous Portal. Cloud hosting is optional.
