Every AI stack has a frontier.
Most teams have never seen it.

Our partners

Own the cost-quality frontier across your entire stack

Intelligent Gateway

Drop-in endpoint that reduces token waste based on your agent traffic, not just per-token pricing.
Explore Gateway

Harness Optimization

Surfaces the best harness configuration by searching against your own private evals.

Dedicated Model

AI21 tunes small open models to match frontier quality on your workloads – at a fraction of the price.

End-to-end control of the enterprise AI stack

[Swap the endpoint]

Point your existing agent at the Gateway. Routing, caching, and compaction start working on live traffic after just a two-line setup. Most teams see spend drop within a day.

[Tune the harness]

Set a cost ceiling and a quality floor. The Harness Optimizer finds the strategy that checks both boxes via automatic search across 1000s of configurations and parallel examination of cheaper options.

[Own the model]

Once you have defined workloads up and running, we distill a dedicated model on them. You get the same accuracy as a larger frontier model, with compounding improvement that is yours alone.

Frontier quality,
30% of the cost

By combining cheap OSS models and frontier models via intelligent routing, budget-aware execution strategies in the harness, and custom trained validators, we keep pushing the cost-quality frontier even higher.

Token spend isn’t going down. You need more than naive routing to manage it
