Optimized model routing: DeepSeek first, cascade on failure
zainhas · x · 2026-08-15
Proposes optimized routing strategies for DeepSeek-V4 Pro, Sol, and Fable:
- Two-stage routing: Run DeepSeek-V4 Pro first and escalate to Sol only if tests fail. This achieves 83.0% resolution at $3.35 per task, beating Sol alone (72.7%, $8.37).
- Three-stage stacking: For max quality, stack Pro, then Sol, then Fable on failures. This hits 90.2% resolution at $7.04, nearing the 96.5% union ceiling and still cheaper than one Fable run.
- Comparison: A perfect one-shot oracle router would score 86.9%; the cascade beats it but with much higher e2e latency.
