The Case for LLM-Agnostic Platforms

Why Single-Model is Risky

1. Vendor lock-in — Tied to one provider's roadmap
2. Price vulnerability — No negotiating leverage
3. Capability gaps — No model excels at everything
4. Future uncertainty — Best model changes over time

Benefits of Multi-Model Approach

1. Best tool for task — Route queries intelligently
2. Cost optimization — Use premium only when needed
3. Redundancy — No single point of failure
4. Flexibility — Adopt new models easily
5. Negotiating power — Competition benefits you
