Open core
Open where lock-in matters. Paid where accountability matters.
The Astrolift AI and Zentinelle AI cores are MIT-licensed. Inspect them, fork them, and self-host them. Calliope AI Workbench is commercial. Support, implementation, and Forward-Deployed Engineering are how teams add an accountable operating relationship around the stack.
The model
The license is not the operating model.
The MIT cores are useful on their own. A technical team can run Astrolift AI for deployment and runtime or Zentinelle AI for agent observability and policy without buying a software license from Calliope AI.
What open source does not decide is who integrates the product into your environment, responds when it fails, maintains the deployment, answers the security questionnaire, or helps the team operate it well. That accountability is the commercial relationship.
Calliope AI Workbench is a separate commercial product. It gives builders the sanctioned daily environment that the operating cores do not attempt to be.
Self-host or add Calliope AI
Where the line sits today.
| Self-hosted core | Commercial relationship | |
|---|---|---|
| Software license | MIT for the Astrolift AI and Zentinelle AI cores | Per-seat commercial license for Calliope AI Workbench |
| What you run | Astrolift AI runtime, Zentinelle AI control layer, or both | Workbench, supported open-core products, or a composed stack |
| Deployment | Your team installs and integrates it | Self-service plus scoped implementation or assisted onboarding |
| Support | Community and your own operators | Named support scope, escalation path, and optional SLA |
| Governance | Zentinelle AI core policy and evidence capabilities | Implementation, policy design, integrations, and operational support |
| Security review | Your team prepares the architecture and evidence | Current packet, questionnaire support, and an engineer in the review |
| Accountability | Your team owns the result | Responsibilities are written into the purchased support or services scope |
| Cost | No license fee for the MIT cores | Workbench seats, support, implementation, or engineering services |
