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.

Hermes Cloud agents now open in a browser tab with the exact same interface as Hermes Desktop. https://t.co/4Vw3XJgFwn To launch a personal agent, pick a name and a model in Nous Portal. We host it for you and it runs 24/7 in its own container, so it can handle scheduled jobs and answer you on any channel while your laptop is closed. Chats, Group Chats, plugins and settings in the Webapp work the same way they do when you run Hermes on your own computer. Open your agent from Nous Portal on your phone or any computer, or connect Hermes Desktop to it and continue the same chats there. Plus, Super, and Ultra plans each include one Cloud agent out of the box. Using Hermes from anywhere has never been easier.
Using an agent that can change its models or code at any time without telling you is like building on quicksand

Hermes Agent can now review your codebase for security bugs with the new official Security plugin by @mark_s. Hermes first maps what an attacker could reach and which inputs it trusts. It splits the code across parallel subagents, checks every candidate finding against the code, and traces whether an attacker can actually exploit it. Turn on test confirmation and Hermes writes a small reproduction for each finding and runs it in a temporary copy of the repo. Each report records the evidence and the findings Hermes ruled out, and exports to SARIF for your existing tools. Run it from chat, the CLI, or the Security page in Hermes Desktop.
