How it works

We prove a cheaper model matches
before we switch you to it.

Four stages. Your baseline is protected the whole way. If we can't prove it, we don't route it.

STAGE 01 / 04

Without Parity Layer

Every request goes straight to your AI provider.

You pay full price on every call. No alternatives tested. No data on what else might work. This is where every AI-native team starts, and where most stay.

STAGE 02 / 04

Swap to our SDK

Two lines. Parity now sits in the middle.

We forward every request to your baseline provider, same model, same output. Nothing changes for your users. No prompts rewritten, no schemas touched.

STAGE 03 / 04

How we prove (in parallel)

A cheaper model generates equal or better output, behind the scenes.

In parallel, Parity uses our patent-pending process to get a cheaper model to generate equal or better outputs than your original model. Nothing about your live traffic changes. This runs behind the scenes. Zero risk.

STAGE 04 / 04

Once proven, we route

You set the thresholds. When they're hit, we flip the route.

You define the proof and confidence thresholds for each prompt. Once achieved, for example 95% confidence and 100+ matches, we automatically switch to the specialist model, maintaining quality while reducing cost by 30-60%. If quality drops, we immediately fall back to your baseline.

Upload a sample of your past requests, a JSONL export, and we'll prove a cheaper model matches your results before you change a single line of code.
