Save 80% of API costs with smart routing
March 12, 2025 ยท 7 min min read
Many teams send every prompt to the same model - even when requests are simple. This is where unnecessary cost is created.
Core idea
Create one virtual model and route by request class:
- Low Cost for routine tasks
- Balanced for most workloads
- High Quality for complex tasks
Result
In typical support and assistant scenarios, savings of up to 80% are realistic without reducing perceived answer quality.
Minimal rule
if prompt_complexity < threshold => low_cost_model
else => high_quality_model
Start simple, measure response quality, then tune thresholds.
