Hermes Agent, published by Nous Research in early 2026 under the MIT license, is one of the most dynamic AI agent projects of the moment: a persistent self-hosted agent with local memory, a skills system that improves with use, and sandboxed execution. Over 175,000 GitHub stars in four months.
The AIOS shares two strong convictions with Hermes: an assistant must have durable memory, and your data must stay with you. The difference is the same as with the other big open source projects: Hermes is a framework to install and keep alive, the AIOS is a complete service built for business owners.
The comparison at a glance
| Criterion | AIOS | Hermes Agent |
|---|---|---|
| What it is | A complete AI operating system, delivered turnkey | An open source autonomous agent framework (MIT) |
| Who it is for | Business owners and non-technical teams | Developers, researchers, seasoned tinkerers |
| Installation | Done for you: dedicated server in France, ready in 24h | Do it yourself on your machine or server |
| Memory | Full company memory (business, clients, style, history) | Persistent local memory, fed through use |
| Business use cases | Configured with you: email, quotes, follow-ups, monitoring, content | Build them yourself through the skills system |
| Maintenance | Handled by the AIOS team | On you |
| Human support | Yes: onboarding, training, support | Documentation and community |
| AI model | Included in the subscription | Bring your own |
| Price | Monthly subscription, 7-day trial without a credit card | Free (minus infrastructure, models and your time) |
When to choose Hermes Agent
- You are a developer and want an agent to shape in depth, skill by skill
- You want to experiment with the best of open source research without depending on a vendor
- Installation, maintenance and security do not scare you
When to choose the AIOS
- You want persistent memory and data ownership without the technical project
- Your need is business (saving hours on admin), not technological
- You want a human counterpart who configures, trains and fixes
Our verdict
Hermes Agent is a remarkable project for those who want to build their agent. The AIOS applies the same principles (memory, autonomy, data at home) delivered as a service: installed, configured on your real use cases, and supported.
