Spend
$21,600
AI spend control for teams that need proof.
See and control every AI dollar. Then spend less of it.
Cost per feature, team and agent. Budgets and hard stops that never fail open. Then send requests to parezen/auto: Parezen routes each one to the cheapest model your team has approved, checks quality on live answers and rolls back on its own. Every saving is matched to your provider bill.

Every request, sent to the model that does the job.
Parezen sits between your app and every provider. Send parezen/auto and each request goes to the cheapest model your team has approved. A model is approved only after it matches your usual model, it is checked on a sample of live answers, and it is removed at once if quality drops. Every response says which model answered, what it cost and what it saved.
Requested model Cheaper model that passed your quality bar

Read the bill
Parezen reads the usage you already pay for and splits it by feature, model and team. You see which part of the product spends what.
Spend by feature, one month
- 2
Find the cheaper path
For each feature it looks for a smaller model, a cache or a shorter prompt that does the same job, then tests it on a sample of real requests before anything changes.

Count it against your baseline
Every saving is the gap between what the same work cost before and what it costs now, at the same prices. It becomes verified when the month matches the provider bill.

Example situations
Where AI bills leak, and the ways to save.
The figures below are a sample company, not a customer.
Expensive model, cheap work
Routine replies priced like the hardest task.
Cache left off
The same prefix billed on every call.
No baseline, no saving
A lower bill still needs the same work.
Example savings path
High assumption, $20,000 a month. Overlap removed, so this is less than adding the lines.

From your first audit to how you buy AI compute.
Roadmap. Nothing on this list is live yet.
Savings forecast
See where the money goes, from a usage export or a read-only connector.
Verified savings
Every saving counted against your baseline, then matched to the provider bill.
Cost per task
Agent and task budgets, priced per outcome instead of per token.
FinOps and governance
One place for spend, budgets, keys and policy across every provider.
Self-tuning routing
Routing that improves itself, inside the rules and quality bar you set.
Buying AI compute
Pooling demand so teams pay less for the same capacity. A later decision.
Your data, your call.
Hosted or in your cloud
Parezen runs it at api.parezen.com: change one URL and bring your own provider keys. Or run it in your own cloud with a self-hosted licence, so keys and prompts never leave your network.
Metadata by default
Tokens, model, cost and latency. Prompts and replies are kept only for workspaces that turn logging on.
Always a way out
If Parezen is ever unreachable, your app can call your provider directly. Budget stops still hold.
Read-only billing access. Prompt capture stays off unless you turn it on.
Pricing
No subscription. Every feature on every plan.
Parezen credits
8%
When you add credit. One key for every model, at the provider's list price.
Your own keys
3%
Above $10K a month; free below it. Never more than we save you on the traffic we optimise. Your providers bill you.
Savings share
15%
Instead of 3% on your own keys. Of the savings, for 12 months per change.
Enterprise
$36K
A year minimum, credited against fees; own keys at 2%. SSO and SCIM, allowlists, zero retention, EU or US region, invoicing and an SLA. Self-hosted: $30K licence plus 15% of savings.
Pay a share only of savings we verify
- No platform fee and no token markup.
- 15% of verified savings for 12 months per change.
- Capped at 5% of the pre-change spend of optimised workloads.
- If verified savings are not above the fee, the share is $0 that month.
Full terms
The savings share is optional: 15% of verified savings for 12 months per change, capped at 5% of the pre-change spend of optimised workloads. If we don't save you more than we charge, you pay nothing that month. That waiver applies only to the savings share.

Questions
What access do you need?
Nothing that can change your traffic. Upload last month's usage or billing export (Excel or CSV), or connect a read-only billing key. No prompts are needed.
Does my traffic change?
Not for the savings forecast: it only reads your bill. To cut spend you change one URL and send parezen/auto. Auto uses a cheaper model only after it matches your usual model on your test questions and on live checks, and removes it at once if quality drops.
How is a saving counted?
Your usual model's cost minus the actual cost, on the same request, at the same price version. Every response carries both. Each month the ledger is checked against your provider bill; only savings within 2% of that bill are verified.
Which providers can the savings forecast read?
Any provider, from an uploaded export. Read-only connectors cover OpenAI, Anthropic, and the AWS, Azure and Google Cloud billing exports. These are providers Parezen works with, not customers.
What does it cost?
No subscription. 8% when you add Parezen credit, your own provider keys free to $10K a month and then 3% (never more than we save you on the traffic we optimise), or a savings share instead. Enterprise is an annual contract. The savings forecast is free, with no card.
Where is my data stored?
In Parezen's database on its hosted service. Provider keys are encrypted and shown only by their last four characters. By default Parezen keeps metadata (tokens, model, cost, latency), not your prompts.
