 The system was designed with a **custom handover mechanism** instead of the A2A (Agent-to-Agent) protocol for the following reasons:
 
 1. **Simplified Architecture**: The current two-agent system (generator + reviewer) doesn't require the complexity of full A2A orchestration
-2. **Direct Integration**: MCP server provides direct access to Imagen3 without needing agent-to-agent communication protocols
+2. **Direct Integration**: MCP server provides direct access to Imagen4 without needing agent-to-agent communication protocols

 4. **Deployment Simplicity**: Hugging Face Spaces deployment is more straightforward without A2A dependencies
 5. **Resource Efficiency**: Fewer moving parts means better resource utilization in the cloud environment
