Hermes Agent is one of the fastest-growing open-source agent frameworks of 2026. Its bet is depth over breadth: an agent that gets better at your specific workflows over time, with memory that persists across sessions.
What is Hermes?
Hermes Agent is an open-source AI agent framework released by Nous Research in February 2026. It is built around a single principle — the agent should improve at your specific workflows over time — and grew to over 100,000 GitHub stars within its first few months.
Key features
- Self-improving skills — the agent refines how it handles your recurring tasks rather than starting fresh each time.
- Persistent cross-session memory — context and learned behaviour carry over between runs.
- Open source — self-hostable and inspectable, from Nous Research.
- Depth-first design — where multi-channel runtimes chase breadth, Hermes optimises for getting a specific job done well.

Learn to build with agentic coding tools
Tools change monthly; the engineering skill does not. AITraining2U's AI Engineering course teaches the RAG, MCP and production patterns behind every coding agent, and Claude AI for Business plus Claude & Multi-Agent Orchestration cover Claude Code and multi-agent workflows hands-on. Both are HRD Corp (HRDC) claimable for Malaysian employers.
