Product
One control plane between your app and every AI model.
Parezen reads the AI usage you already pay for, sends each request to the cheapest model that still clears your quality bar, and counts every saving against your own baseline.
Early access. The X-ray is planned and not live yet.

Providers Parezen is built to work with, not customers.
Four steps. One ledger.
The same loop for every provider and every feature. Each step is planned.
Connect
Upload a usage export or connect read-only billing. Nothing in your traffic changes to start.
PlannedSee
Spend by provider, model, feature, team and agent, in one place, with budgets and hard stops.
PlannedCut
A smaller model, a cache or a shorter prompt, switched on only after a shadow test passes your quality bar.
PlannedProve
Every saving is a ledger line against your own baseline, then matched to the provider invoice within 2%.

Four modules. Start free.
Pick the modules you need. Prices follow your tracked AI spend, billed annually.
- Free
Core
Organisation, users, projects and provider connections. Free under $1,000 a month of AI spend. We plan to open-source it.
See pricing - From $49/mo
FinOps
Spend analysis, budgets and alerts, chargeback, the savings ledger and the match against your provider bill.
See pricing - From $49/mo
Inference
The gateway: routing, semantic caching, shadow tests and fallbacks. Full prompt capture stays off unless you turn it on.

Governance
Policies, approvals, guardrails, roles and the audit log, across every provider you use.

See where the money actually goes.
Switch the breakdown between provider, model, feature and team. The same sample month stays in view, and every total adds up to the same bill.
- Read-only. No change to your traffic.
- Your own baseline, not an industry average.

Ways to spend less
Each lever has a stop. Anything that can change answer quality waits for a passed shadow test.
- Lever 1
Right-size the model
Send simple requests to a smaller model that still clears the quality bar.
How it works - Lever 2
Cascade
Try a cheap model first and escalate only when a check fails.
How it works - Lever 3
Provider prompt caching
Reorder prompts so stable parts qualify for cached-token discounts.
How it works - Lever 4
Response cache
Exact-match cache is in the gateway prototype. A semantic cache would come later.
How it works - Lever 5
Prompt and context trimming
Flag duplicate system prompts, oversized context and repeated instructions.
How it works - Lever 6
Output control
Set length limits, structured output and reasoning effort per route.
How it works - Lever 7
Batch routing
Move async work onto discounted batch APIs.
How it works - Lever 8
Waste removal
Catch retry storms, duplicate calls, agent loops and stale test keys.
How it works - Lever 9
Host arbitrage
For an open-weight model, pick the cheapest healthy host.
How it works - Lever 10
Shadow testing
Replay a sample of real traffic and score it before any switch.
How it works - Lever 11
Distil or fine-tune
Advise a tuned small model where one high-volume task would pay off.
How it works - Lever 12
Commit advisor
Advise on provider commitments and credits from actual usage.
How it works - Lever 13
Cross-provider switch
A cheaper model from another provider you connected, only after a replay of your own requests holds quality. Not built.
How it works
Every saving has a line. Every line has a baseline.
- The baseline is the model you asked for, with no levers, at the same price version.
- Estimated, then realised on real traffic, then verified against the provider bill.
- The total is always the sum of its lines.
