Cooper bills in AI Credits. A credit is a unit of platform value — not a token, a prompt, or a request. HonestHosting converts what the underlying AI provider charges into credits behind the scenes, so your pricing doesn’t shift when we change models or providers, and a single balance covers every model regardless of what it costs us per token.
Credits cover every part of a turn: Cooper’s reply, any tools it runs along the way, and the title and summary it writes for you. A more capable model costs more credits per turn, which is why the default suits most work — see New Session for how model selection works.
The chat shows what the current conversation has used, as a number of prompts and credits alongside the same figure in dollars. That only ever covers the conversation you are looking at, never your account as a whole.
Keeping a conversation compact also keeps its cost down. A long conversation re-sends more context on every turn — see the Context & Compaction section of New Session.
Your remaining balance appears in the chat as <n> credits left, and on your Account page under COOPER.
Every account starts with some free credits.

When your balance reaches zero, Cooper pauses — it will not start a new turn until you top up — and offers two ways to do that:
Purchase more — a one-time credit pack.Subscribe monthly — a recurring monthly allotment.You can reach both at any time from the Cooper page; you don’t have to wait until you run out.

Purchase more opens Purchase Cooper Credits. Select the pack you want and continue to payment:

You are redirected to a Stripe Checkout session. Once the payment completes you are returned to Cooper, and your balance updates to include the new credits.
Purchased credits do not expire. They roll over indefinitely until you spend them.
Subscribe monthly opens Monthly credits, where you pick a tier and a quantity. A subscription grants more
credits than buying the same tier once, which is what makes it worth having.

Two things to know about how it bills:
That expiry is the only difference between subscription credits and purchased ones — and it is why the order credits are spent in matters.
When a turn costs credits, they are drawn in this order:
Credits that expire are always spent before credits that don’t. So if you subscribe monthly, burn through that allotment, and then buy a one-time pack, the pack is still there at the start of the next cycle — only the platform-issued allotment lapses.
Your balance is a single number. The categories above only determine spending order; you never have to choose which credits to use.
