Why Air Router
Same Coding Experience. Smarter AI Spending.
Your coding agent handles development. Air Router makes every AI request more efficient.
-
Intelligent Model Routing
The right model for every task.
Simple coding tasks use efficient models. Complex reasoning tasks get more capable models when needed.
-
Token Optimization
Stop paying for unnecessary context.
Reduce redundant input tokens while preserving the context needed for coding tasks.
-
Smart Caching
Don’t pay twice for repeated work.
Reuse eligible cached responses and avoid unnecessary duplicate model requests.
-
Agent Cost Protection
Keep runaway costs under control.
Use budgets and safeguards to manage expensive agent loops and repeated requests.
How it works
Connect Once. Optimize Every Request.

The Air Router advantage
Your Agent Stays the Same. The Backend Gets Smarter.
| Without Air Router | With Air Router |
|---|---|
| Fixed model selection | Intelligent model routing |
| Repeated context processing | Context optimization |
| Unnecessary duplicate requests | Smart caching |
| Limited cost controls | Budget and usage controls |
| Manual model decisions | Automatic task-aware routing |
Spend more time building. Less time managing AI costs.
