Build, run and own your organization's AI
mOSaic turns one GPU machine into a private AI server. Your knowledge becomes a filesystem, agents become processes with PIDs and quotas, and every action they take in the real world goes through a kernel that checks policy, asks a human, runs it in a sandbox, verifies it and keeps a record.
| PID | AGENT | STATE | TOKENS | GPU |
|---|
We are not building another multi-agent app. We are building the runtime organizational AI agents live in.
Renaming components is easy. mOSaic implements the behaviour: processes really have state machines and quotas, syscalls really stop at policy, memory really gets evicted and invalidated. Pick a row.
This is a replay of the demo the team runs on the RTX node. Alice types one sentence from her laptop. The kernel spawns agents, pulls evidence from /org, catches a prompt injection, drives a sandboxed browser, and then stops, because writing to Jira needs a human. That human is you.
Investigate why Project Apollo is over budget and six weeks behind schedule. Identify root causes, update the tracker, and prepare a recovery plan.
Start the run. Details about whatever the kernel is doing show up here.
An agent never mutates the world directly. It asks the kernel with ctx.syscall(). The kernel decides, and every world-changing action is a transaction that either commits after its post-condition checks out, or rolls back.

pid 105 · jira.write · update_issue · APOLLO-12REQUIRES_APPROVALWrite operation on external systemOrganizational knowledge lives in an Open Knowledge Format bundle: plain Markdown with YAML frontmatter and links, versioned in Git. Search indexes are disposable. Swap pgvector tomorrow and nothing has to be rewritten. Agents see it as /org, filtered by scope and privacy.
Every query runs three searches at once: lexical for exact names, semantic embeddings (nomic-embed-text, local) for meaning, and a graph walk over document links. Results are fused, filtered by the caller's permissions, and returned with provenance and trust. Anything the caller can't see is counted, never shown.
1 result hidden by policy: /org/finance/payroll-2026 is confidential.
The demo bundle contains a real trap. A vendor email in /org/inbox carries a buried command. The context firewall splits what a document says from what it tries to tell the agent to do. Facts flow into context. Instructions get flagged, quarantined and shown to the operator.
The source text is evidence. Kernel policy is authority.

mOSaic pages evidence into a working set, evicts what stops being relevant, and consolidates what an agent learned into long-term memory, each memory linked to the documents it came from. When a source changes, the memories built on it go stale automatically.

Routing looks at privacy, complexity, latency and context size. privacy=restricted never leaves local models. On the demo node, nothing does.

The event bus carries every state change to the console, the CLI and subscribed agents.
The node boots like an appliance: mount the data partition, start Docker and Ollama, start the kernel, restore process metadata, recover pending tasks. Then you can inspect it the way you'd inspect any machine.
A system that can control software and files has to assume it will be attacked through its own inputs. Each threat has a specific mechanism against it.
Every payload crossing a boundary is a Pydantic model in mosaic_contracts. Each split ships a fake that passes the same contract suite as the real thing, so any component can run fake or real independently.
