An engine of layers.
A request-level gateway sees one call at a time. Layer X1 sees the whole trajectory — and runs it through a stack of layers, each one a decision your agent never has to make.
- 01
Cache
We keep the prompt prefix warm across the whole run — not a single call. Your agent sends the same request it always did; the cache lives underneath, so repeated context stops costing full price.
- 02
Route
Every step is scored against 70+ models. Layer X1 chooses the least-cost path through the entire trajectory, not the cheapest individual call — cheap where it's safe, strong where it counts.
- 03
Branch
Sub-tasks fork onto cheaper branches while the main trunk stays pinned to one model. Context never fragments, and the expensive model only runs where it earns its keep.
- 04
Escalate
When a step stalls or fails a check, Layer X1 climbs to a stronger model and retries automatically. The agent keeps moving instead of dead-ending mid-task.
Put the layer under your agent.
One environment variable. Your agent doesn't change — everything underneath does.
