Your machines.
Your agents.
The core is Apache 2.0 licensed, including for commercial use. Run it on machines you control, with compatible hosted or self-hosted models.
The website and Docs are a public preview. The software has not been released; the source repository remains private and Hub access is coming soon.

Software licence for the core
You provide the infrastructure and model services. Their bills and the work of operating the deployment remain yours.
Read the licenceIncluded in the core
- Agent runtime and jobs
- Run the model and tool loop, record each job and recover work using the mode you choose.
- Explore
- Budgets and quotas
- Set spending limits, track model costs and reserve the budget before a model call in strict mode.
- Explore
- Machines and isolation
- Send work to the right machine and limit what it can access. Isolation varies by operating system and workload.
- Explore
- Identity and data
- Connect your sign-in provider, assign roles, choose where job data lives and decide how long to keep it.
- Explore
- Security fixes
- For supported versions. Budgets, approvals, audit and the other safety features stay in the open-source core.

What you operate
Run and update the server, its database and your nodes. Manage access, backups, keys, model credentials and plugin permissions. Choose where data may go and how long to retain it.
Deployment responsibilities| The agent | Chooses its next step using the tools and information available. |
|---|---|
| oz0 | Runs the default agent loop, applies relevant permissions, approvals and budgets, and records execution. |
| Your team | Chooses plugins and providers, grants access, sets limits and operates the deployment. |

Models will change.
Keep your foundation.
Models you can run yourself are becoming more capable, and teams already use them alongside proprietary models.[1] Shared standards are helping agents and tools connect across vendors.[2]
oz0 keeps jobs, permissions, budgets and history together as you change compatible models or connect more systems.

The model is part of the result.
An agent’s harness is the software that manages its context, tools and execution. Research shows that changing it can substantially change benchmark results with the same model.[3] Those scores describe a complete setup.
oz0’s default runtime manages the model → tool → result loop. External harnesses are optional. Our vision is a shared foundation people can run, improve and redistribute, with control over models, permissions and costs.
Read our visionDifferent agents. Different models.
Specialist models already exist for areas such as finance.[4] We expect specialists and general models to work side by side. oz0 lets you configure a compatible model for each agent.
| Agent’s task | Model to evaluate |
|---|---|
| Write code | Coding model |
| Analyse financial reports | Finance-focused model |
Licence and ownership
Can a company use the core?
Yes. Apache 2.0 allows commercial use, modification and distribution. When redistributing, include the licence, preserve required notices and mark modified files. Keep any applicable NOTICE attributions.
Where does it run?
On machines you control. Run the server and join machines as nodes. Connect compatible hosted or self-hosted models; model serving is separate from oz0.
Will the safety features stay in the core?
Yes. Budgets, approvals, the audit trail, sign-in and the other features that keep a cluster safe stay in the open-source core, in this version and later ones.
