Our New Report "Hermes: The Moat Above the Model" is live!
Hermes is the AI agent that belongs to you.
Your agent builds valuable context about you with every session. When you switch models, you can't take any of this with you. What a closed agent learns about you is its product. You are renting your own work back.
Hermes breaks this model by keeping everything it learns on your machine. Between sessions the agent reviews its successful runs and writes them into reusable skills using GEPA, which beats reinforcement learning with 35x fewer rollouts. These skills travel with you when you switch models.
Two years before Hermes shipped,
@NousResearch was already building the fine tuning and reinforcement learning pipelines for their open-weight models. In the last week of May, Hermes was OpenRouter's highest volume app with 4.5 trillion tokens routed currently.
At Hermes's scale, that signal lets Nous keep improving the user experience. Your memory and skills stay on your machine the whole time.
