# Cost-Aware LLM Pipeline
Patterns for controlling LLM API costs while maintaining quality. Combines model routing, budget tracking, retry logic, and prompt caching into a composable pipeline.
## When to Activate
- Building applications that call LLM APIs (Claude, GPT, etc.)
- Processing batches of items with varying complexity
- Need to stay within a budget for API spend
- Optimizing cost without sacrificing quality on complex tasks
## Core Concepts
### 1. Model Routing by Task Complexity
