Nous Research announced the public preview of Hermes Desktop on June 2 — a native application for macOS 12+, Windows 10/11, and Linux that brings its open-source Hermes Agent framework out of the browser and onto the desktop. Released at version 0.15.2 under an MIT license, the app was first shown publicly during Nvidia CEO Jensen Huang’s GTC keynote. Hermes Desktop gives the agent a persistent, device-level presence, maintaining a unified memory and identity across Telegram, Discord, Slack, WhatsApp, Signal, email, and a CLI — described as “one agent, one memory, every surface.”
Six capability areas ship in the preview: persistent memory that auto-generates skills and retains problem-solving history across sessions; natural-language scheduling for unattended automation of reports, backups, and briefings; isolated subagents with dedicated terminals and Python RPC scripts for zero-context-cost parallel pipelines; web search, browser automation, vision, image generation, text-to-speech, and multi-model reasoning; and sandboxed execution across five backends — local, Docker, SSH, Singularity, and Modal, with container hardening and namespace isolation. Nous Portal paid tiers (Plus, Super, Ultra) provide monthly credits alongside access to over 300 models with built-in tool use. Hermes Agent has become one of the most widely deployed open-source agent frameworks; as of mid-May, OpenRouter data showed the framework hitting 291 billion daily token calls and over 1.75 trillion in a single week, and it has been integrated as a preferred runtime by Xiaomi MiMo and other major model platforms.
