What changes
Why teams switch
Outcomes on the stack you already run. No rip and replace.
-
Lower LLM spend
30–60% lower API spend. Same workflows. Smarter routing per cluster.
-
PM-ready dashboards
Decision support for cost, quality, and rollout. Auditable tradeoffs PMs and leads can defend. Not infra-only config.
-
Traffic stays current
Track production traffic as it shifts. Clustering and policy adapt with it.
-
Fast and reliable
~2–3ms vs 50–100ms on gateway routers. 10× more reliable.
-
Fits your stack
Fits the stack you already run, including LangChain, LangSmith, Langfuse, and the rest of your observability and orchestration tools. No parallel pipeline.
-
Unified billing
One spend view across providers. We manage keys and routing surface.
-
Orchestrated rollout
Shadow, compare, scale. Your pipeline stays intact. Policy changes tested on prod traffic first.
Pipeline
In process: pick the right model per traffic cluster. Versioned policy you can defend. Three modes on one path: capture, validate, route.
Operating modes
Compare
Shadow and A/B on replayed prod data before you widen rollout.
