At Anvil Coder the plan is the model tier: it decides which model class an organisation's runs work with — the Haiku, the Sonnet or the Opus class. Five plans from $0 to from $2000 per month, and the tier can be switched at any time.
Five plans, one principle: each of them stands for a model tier. Free costs nothing and works on the same tier as Starter; Enterprise is a contact plan and is arranged rather than selected.

Model tier by arrangement
Dedicated workers, dedicated operations — in your own data centre on request.
Book a conversationPrices are per organisation and month, in US dollars. What a run consumes at the model provider comes on top — see the section after next.
A plan here is not a feature list but a setting: the organisation's model tier. It is called Low, Medium or High, and it decides which model class does the work — and with it the quality and cost of every single run.
A project can also leave the choice to the service (optional, off in the default delivery): it then starts on the cheapest rung and climbs only when verification fails — at most up to the plan's tier. That saves money on simple tasks without making the hard ones worse.
The plan price is not the model price. Every run consumes at the model provider, and what it consumed is recorded per run and shown in the billing view. A long, repeatedly repaired run costs more there than a short one — the plan's tier sets the price per call, not the number of calls.
Whoever stores their own model key settles directly with the provider. That does not depend on the plan: each organisation sets its key itself, and on the Claude paths the service requires it anyway — the security page describes how it is stored and what happens without it.
Cost ceilings for organisation, project and single run can be set. How they work and what applies without a set amount is on the operations page — in one place, so two pages do not tell two versions of the same thing.
This page is preliminary. It names the plans, their prices and the one thing a plan really decides today: the model tier. Deliberately, nothing more.
A paid plan today is arranged in a conversation: the organisation's owner sets the model tier in the settings, but there is no self-service checkout in the cockpit yet.
Volume quotas — runs, projects, sandbox time — are not part of a plan today. The service can enforce them, but in the default delivery it does not: without set values, unlimited applies. A number in a plan card would therefore be neither a claim for the customer nor a limit for us — just a number.
We also make no availability commitment. The service currently runs one instance of each data store, and such a commitment is a contract, not a marketing line. We write this down instead of omitting the line: whoever compares plans looks for exactly this gap, and finding it unnamed weighs more than reading it.
What changes, changes here first. If quotas or commitments arrive, they appear on this page before they appear on an invoice.
