Overview
Gizzi is the core runtime engine that executes agent code. It provides a secure sandboxed environment for running agent logic while managing state, memory, and communication with external services.Execution Model
Gizzi uses a message-passing execution model where agents communicate through channels. Each agent runs in its own isolated context with access to:- Memory store - State persistence across executions
- Skill registry - Capability discovery and invocation
- Message bus - Inter-agent communication
- Model gateway - LLM interactions
Runtime Versions

Agent Lifecycle
Sandboxing
Gizzi provides multiple sandboxing levels:Memory Management
Agents can persist memory across executions:- Session - Lost when agent stops
- Persistent - Stored in database
- Shared - Accessible across agents
Model Integration
Gizzi supports multiple LLM providers:- Allternit gateway (all models via aliases)
- Local (Ollama, MLX, Bonsai WebGPU)
