Pricing

Patent Pending

We charge just like
AI APIs do.

Per request, per token. No subscriptions, no seats, no minimums. You only pay the new (lower) token rate for the models we've already proven can handle your prompts.

Phase 1

We prove routing for free.

Try Parity free on up to 10 prompts. We optimize cheaper models against each one and prove the result on your own traffic — you pay nothing to see it, no credit card required.

  • Up to 10 prompts proven free
  • Tested on your own prompts
  • Full proof report included
  • No credit card, no commitment
Only when you save
Phase 2

You pay when we route.

Once a prompt type is proven equivalent, we start routing it to the cheaper model. You pay per-token at the new (much lower) rate — which is 30–60% less than you were spending on your baseline.

  • Per-request, per-token pricing
  • Billed at the cheaper model's rate, not your baseline
  • Transparent: see every saved dollar in your dashboard
  • Instant rollback if quality ever drifts

How the math works

You always save more than you pay.

1

You hit our API with your existing SDK.

Drop-in replacement for OpenAI, Anthropic, Google. Two-line change.

2

We run your baseline model and return the response.

You pay your normal baseline provider (OpenAI, Anthropic, etc.) directly — we pass through.

3

In the background, we test cheaper models against it.

Completely free. Statistical proof required before we recommend any switch.

4

When proven, we start routing — and that's when we bill.

Per-token, at the cheaper model's rate. You keep the delta between what you would have paid and what you actually paid.

Example

You were spending $10,000/mo on Claude Sonnet for data extraction. We prove DeepSeek V3 produces better output for that prompt type. We route it there. Your new bill for those tokens: $4,000/mo. You save $6,000/mo. You pay Parity Layer at DeepSeek's rate, not Claude's.

Common questions

Is there a free tier?

Yes. Your first 10 prompts are free — proven on your own traffic, no credit card required. You're only billed once a prompt is proven and we start routing traffic through the cheaper model.

Do I still pay my baseline provider?

Yes — during the proof phase, your baseline traffic goes directly to your existing provider using your own API key. We don't mark it up, we don't add a fee.

How is this different from just using a cheaper model?

We statistically prove the cheaper model produces equivalent output for your specific prompts before switching. Most teams guess. We verify.

What happens if quality drifts?

We monitor every routed request and instantly fall back to your baseline if the cheaper model ever fails validation. Zero risk to your users.

Enterprise contracts?

We offer custom SLAs, on-prem / VPC deployment, SSO, and audit logs for teams with real AI spend. Get in touch.
