🏗️ Architecture Debate: Monolith Agent vs. Router/Specialist Swarm for Complex SaaS?
Hi everyone, I am building a production-ready SaaS for vehicle damage appraisals (B2B). The system needs to be "bulletproof" as I plan to scale this to multiple clients. The Workflow is complex: 1. Data Collection: gathering 80+ fields (dynamic logic based on private/company, owner/driver status). 2. Document Handling: Requesting specific docs, OCR analysis, and validation. 3. Support: Answering FAQs from a Knowledge Base. 4. Scheduling: Booking appointments. I am currently debating the smartest architecture to ensure reliability and context retention. The Options I'm considering: - Option A: The "God Agent" (Monolith) One single Agent (GPT-4o) with a massive system prompt handling everything. - Option B: Router + Specialists (The Swarm) A fast/cheap Prequalifier/Router (e.g., gpt-4o-mini) classifying the intent, then routing to: My Question: For a high-stakes SaaS where data integrity is key: Is the complexity of orchestrating multiple agents worth it? Or is a single, well-prompted GPT-4o robust enough to handle context switching without breaking the flow? Would love to hear your experiences with production apps! Thanks! 🚀
