Design 5 distinct revenue models for an AI agent that has ingested an entire platform's knowledge base and can act as a platform expert. The agent can answer questions, write code, configure settings, debug issues, and guide users through complex workflows.

For each model:
1. Pricing structure (tiers, usage-based, enterprise)
2. Target customer segment
3. Unit economics (CAC, LTV, margin)
4. Scalability analysis
5. Competitive moat strength

Models to analyze: (a) B2B SaaS subscription, (b) Marketplace/app-store model, (c) Platform partnership/white-label, (d) Usage-based API, (e) Freemium + premium.
