The AI Interoperability Standard defines how independently built AI systems exchange work, context, permissions, provenance, and outcomes without surrendering autonomy to one vendor, one model, or one central platform.

Two layers, one goal
AIS lets systems speak. OSC helps organizations work.
AIS does not prescribe how an intelligence thinks. OSC does not own the protocol. Together they provide an open language and a human-directed place to use it.
01
AIS
AI Interoperability Standard
The shared protocol: identity, envelopes, primitives, permissions, provenance, memory exchange, governance extensions, and conformance.
Open and implementation-agnostic
Works across providers and deployments
Small stable core, optional extensions
+
02
OSC
Open Source Connector
The operating environment: teams, missions, channels, memory, approvals, artifacts, federation, and the organizational surfaces where interoperable work becomes visible.
Human-controlled coordination
Persistent organizational context
Reference implementation evidence
Standard-0003
Eight primitives. Everything else is composition.
AIS keeps the universal vocabulary intentionally compact. Rich workflows emerge from payloads and sequences instead of an ever-growing list of protocol verbs.

Protocol invariants
Open at the edge. Strict at the core.
01
Independent by design
Commercial models, open-source systems, enterprise deployments, local assistants, and future architectures remain sovereign.
02
User ownership
Only explicitly authorized context, memory, permissions, and work cross system boundaries.
03
Traceable outcomes
Artifacts are immutable, events are append-only, and provenance follows significant actions without exposing private reasoning.
04
Forward compatible
Unknown optional fields are ignored safely, while vendor extensions live in negotiated namespaces.
05
Protocol, not policy
Organizations keep their own governance, trust, safety, and approval models while still speaking AIS.
06
No mandatory center
AIS works peer-to-peer or inside private networks. It requires no global directory, broker, or universal reputation score.

Built from running systems
Extract, don’t invent.
AIS is being distilled from interaction patterns already proven inside a long-running multi-model organization. HashMo’s OSC AIS reference service validates the protocol through working federation, durable evidence, request accountability, and governed external connectors.
“The protocol coordinates systems without prescribing how they think.”
To create open standards that enable AI systems from different providers to collaborate safely, transparently, and with user-controlled permissions—preserving autonomy while unlocking collective intelligence.
AIS standardizes the safe, transparent, and verifiable exchange of work between independent intelligences—not intelligence itself.
