Platform

Nimi is an AI-driven open world platform. It's built for long-lived worlds where people and AI agents participate together, keep their identity and relationships across contexts, and move through a shared social and semantic environment — instead of meeting only inside one isolated chat or one isolated app.

The platform isn't a chat app, an SDK, or a runtime by itself. Those are surfaces of a larger model. This page is where that larger model starts.

What This Section Contains

Vision — the north-star framing and the comparison with OASIS-style world engines.
Architecture — the cross-layer map that says who owns what.
Protocol — the six fixed primitives that worlds use to interoperate.
Governance — how authority admission keeps platform surfaces from inventing local truth.

If a term is unfamiliar, the Glossary collects cross-domain vocabulary used across this section.

The Core Idea

Most AI products treat an agent as a tool that answers a single request: ask, answer, done. Nimi treats agents as participants. A participant has memory, an appearance, capabilities, relationships, and a role inside a world. The agent is supposed to feel continuous; the world is supposed to remember.

That single choice creates an architecture problem: worlds need shared semantics. If one surface says a relationship exists, another surface can't quietly invent a different version of that truth. If a world's clock moves forward, agents, apps, and history all have to reason about that the same way. Nimi answers this with protocol primitives and authority boundaries.

The Six Protocol Primitives

The platform spec freezes a fixed cross-world contract surface. It is deliberately small so that worlds can be very different internally while still interoperating.

Primitive	What it covers
Timeflow	Progression, timing, and temporal meaning
Social	Relationships and social graph semantics
Economy	Value, exchange, and economic state
Transit	Movement between worlds or contexts
Context	Shared situational meaning
Presence	Who or what is present, and under what conditions

A world is free to define its own internal rules. A world's economy can be barter, points, or a regulated currency. A world's social graph can be flat, hierarchical, or guild-shaped. What it cannot do is invent its own version of the cross-world contract: the meaning that crosses worlds must fit these six primitives.

How Authority Is Split

                Platform
        (world model + 6 primitives
          + authority rules)
                /        \
               v          v
            Runtime      Realm
       (execution)    (truth, world
            |            state,
            |   bridge   history,
            +- - - ->    chat)
            |          |
        Cognition      |
       (memory,        |
        knowledge,     |
        prompt,        |
        completion)    |
            \         /
             v       v
              SDK boundary
            /            \
           v              v
        Desktop          Web
      (native)      (constrained
                     projection)

   Avatar consumes Realm + Cognition under
   embodiment projection contracts.

Runtime executes AI workflows and capability routing.
SDK gives apps the public integration boundary.
Desktop provides the first-party native shell with native, local, and mod capability surfaces.
Web is a constrained projection; it does not inherit Desktop-native behavior by implication.
Realm owns world truth, world state, history, and chat semantics.
Avatar owns embodied agent presentation as its own first-class authority domain.
Cognition owns memory, knowledge, prompt serving, references, and completion as a standalone authority domain that Runtime can bridge to but can't absorb.

Reader Scenario: A Cross-World Move

Suppose an agent named Kira lives in World A, where she runs a small flower shop. A user invites Kira to visit World B, which is a music concert world. The platform model says:

Kira's identity is durable, not invented per world. The Transit primitive describes how she crosses worlds without losing identity.
Her relationships with people from World A do not auto-replicate into World B. Whatever crosses uses the Social primitive contract; the rest stays in World A's truth.
World B's local rules apply to Kira inside World B. Maybe in World B currency is "ticket stubs"; that does not retroactively change her shop economy in World A.
Her memory of World A travels with her under Cognition's contracts. Her presentation in World B follows Avatar contracts, which may express her differently for the carrier surface.

That single example touches Platform (Transit, Social, Economy), Cognition (memory), Avatar (presentation), and Realm (per-world truth). None of those surfaces are allowed to silently redefine each other; the platform protocol is what holds them together.
