Open models, tailored to your traffic

Shared endpoints price open-source models for the average workload, not yours. We run them on dedicated, optimized compute tuned to your traffic shape, so the cheap option stays predictable under load.

03 · POST-TRAIN

Your own models, trained on your data

Every routed request leaves a trajectory. Train your own model on them — specialized to the work you actually do — and Emissary routes to it automatically when it’s the better call. Your data, your weights.

Cheaper on work you've already seen
Better on your domain than any general model
Faster, because it’s smaller

The more you route, the more trajectories you have to train on — and the router decides when your model is the better call. That’s the loop: routing feeds your training data, training makes routing cheaper.
