• LLM provider integration
• Conversation management
• Streaming responses

RAG Service

• Document ingestion
• Embedding generation
• Vector search

Workflow Engine

• Visual workflow builder
• Task orchestration via Temporal
• Event-driven execution

Data Flow

1. User sends request via Frontend
2. Gateway authenticates and routes to appropriate service
3. Service processes request and returns response
4. Real-time updates via WebSocket or SSE
