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

Intelligent Model Routing

How It Works (ibl.ai)

``` Student Query ↓ Complexity Analysis ↓ ┌─────────────────────────────────────┐ │ Simple/routine → DeepSeek-R1 │ │ Moderate → Llama 4 │ │ Complex → Claude Opus / GPT-5 │ │ Visual → Gemini 3 │ │ Multilingual → Qwen 3 │ └─────────────────────────────────────┘ ↓ Response (Student sees unified experience) ```

Results

• Quality maintained — Premium models when needed

• Costs reduced — 60-85% savings

• Coverage expanded — Every task optimized

• Future-proof — Add new models easily
