Hermes Agent is an 🏷️#open-source AI agent framework from Nous Research (launched July 2025, gaining momentum early 2026). Think of it as a persistent, self-improving terminal agent — not a chatbot, not a coding copilot, but an autonomous agent that lives on your server, remembers what it learns, and gets more capable over time. Built on Hermes-3 (Llama 3.1 fine-tuned with Atropos RL for tool-calling accuracy + long-range planning), it's designed around multi-level memory and automated skill creation — when it solves a hard problem, it writes a reusable Skill Document (Markdown, following agentskills.io open standard) so it never re-learns the same workflow.
