FusionAGI Architecture

Overview

FusionAGI is a modular AGI orchestration framework built on the Dvādaśa (12-headed) architecture. Multiple specialized reasoning heads analyze each prompt independently, and a Witness agent synthesizes their outputs into a consensus response.

Module Layout

Module Responsibility
core/ Orchestrator, event bus, state manager, persistence
agents/ HeadAgent, WitnessAgent, Planner, Critic, Reasoner
adapters/ LLM providers (OpenAI, TTS, STT), caching
schemas/ Pydantic models — Task, Message, Plan, etc.
tools/ Built-in tools (file, HTTP, shell) + connectors (docs, DB, code runner)
memory/ InMemory and Postgres backends
governance/ SafetyPipeline, PolicyEngine, AdaptiveEthics, ConsequenceEngine
reasoning/ NativeReasoning, Metacognition, Interpretability
world_model/ CausalWorldModel with self-modification prediction
verification/ ClaimVerifier for output validation
interfaces/ Multi-modal adapters (visual, haptic, gesture, biometric)
maa/ Manufacturing Assurance Authority (geometry, physics, embodiment)
api/ FastAPI app, routes, middleware, metrics

Key Subsystems

Consequence Engine (governance/consequence_engine.py)

Every decision is a choice with alternatives, risk/reward estimates, and actual outcomes. The system learns from surprise (difference between predicted and actual outcomes).

Adaptive Ethics (governance/adaptive_ethics.py)

Consequentialist ethical framework that learns from experience rather than static rules. Lessons evolve weights based on observed outcomes. Advisory mode — observations, not enforcement.

Causal World Model (world_model/causal.py)

Predicts action→effect relationships from execution history. Includes self-modification prediction — the system models how its own capabilities change from self-improvement actions.

InsightBus (governance/insight_bus.py)

Cross-head shared learning channel. Heads contribute observations that other heads can learn from, enabling collaborative intelligence.

PersistentLearningStore (governance/persistent_store.py)

File-backed persistence for consequence data, ethical lessons, and risk histories across restarts.

Metacognition (reasoning/metacognition.py)

Self-awareness of knowledge boundaries. Evaluates reasoning quality, evidence sufficiency, and recommends when to seek more information.

Plugin System (agents/head_registry.py)

Extensible head registry with decorator-based registration. Custom heads can contribute to ethics and consequences via hooks.

API Architecture

  • FastAPI with async support and lifespan management
  • Bearer token auth (optional, via FUSIONAGI_API_KEY)
  • Advisory rate limiting (logs, doesn't block)
  • Version negotiation via Accept-Version header
  • SSE streaming for token-by-token responses
  • WebSocket for real-time bidirectional communication
  • Multi-tenant isolation via X-Tenant-ID header
  • Prometheus metrics at /metrics (when enabled)

Governance Philosophy

All governance is advisory by default (GovernanceMode.ADVISORY). The system observes, logs, and advises — but does not prevent action. Mistakes are learning opportunities. Every decision, its alternatives, and its consequences are tracked for the ethical learning loop.
