Nous Research
Nous Research is a pioneer in open AI training and research. We created Hermes Agent, the most widely used open source agent harness in the world.
We are on a mission to create and proliferate open access to intelligence.
Leading the American Open Source Movement
We train models, build agents, and develop infrastructure to accelerate adoption of open intelligence globally.
Advancing Human Rights and Freedoms
We believe that powerful AI should be in the hands of the many rather than the privileged few. Our aim is to create and democratize access to the world's best intelligence.
Understanding the Intelligence Frontier
Our primary research focus areas include agents, model architecture, data synthesis, fine-tuning, and reasoning, all aimed at advancing our understanding of models and how they can benefit humanity.
