Terms of use

1. Who you are contracting with

The service at unboundmodels.com is operated by a sole trader registered in the Czech Republic; the trader’s registration details are available on request at [email protected]. Creating an account forms a contract between you and that trader. Czech law applies, and where you are a consumer, the mandatory consumer law of your own country of residence applies alongside it.

2. What we provide

Metered access to open-weight language models we host, through an OpenAI-compatible HTTP API. The models are third-party artifacts published under their own licences; we host and serve them, we did not train them, and we do not warrant what they output. The catalog page links the published weights for each route. API responses do not include checkpoint or revision attestations.

The service is offered without a provider-side moderation layer. That is a product decision, not a promise that any particular output will be produced: models refuse things on their own, change between versions, and are frequently wrong.

3. Eligibility and your account

• You must be at least 18 years old and legally able to enter a contract.
• You sign in with a one-time code sent to your email address, or through Google sign-in tied to the same address; that address is your account. One person or organisation, one account; sharing an account between unrelated parties is not permitted.
• API keys are bearer credentials. Anything authenticated by your key counts as your usage and is billed to your balance, whoever actually sent it.
• Tell us at [email protected] the moment a key leaks and we will revoke it. We cannot reverse spend that has already been metered.
• You are responsible for anyone you give access to, including your own end users if you build a product on top of us.

4. Acceptable use

Your use must comply with the acceptable-use policy, which forms part of these terms. Breaching it is grounds for suspension or termination under section 10.

5. Credit, metering and billing

• The service is prepaid. You top up a balance and it is drawn down per token at the rates published on the model page at the time of the request.
• Usage is metered from the inference engine’s token counts. Response usage reports repeated input as discounted_tokens, separately from physical GPU cached_tokens; for streams, request stream_options.include_usage to receive final usage.
• The repeated-input rate applies to matching token prefixes across your API keys on the same account and model build within a rolling five minutes after a successful metered completion. Eligibility is captured at request admission; failures and cancellations do not renew it. The discount does not depend on GPU cache residency and does not guarantee time to first token.
• Model warm-up time is not billed. Token charges settle only on successful metered completion.
• A request that fails or is cancelled before successful metered settlement is not billed, and its reservation is released. Cancellation after settlement does not reverse a completed charge or its repeated-input eligibility.
• When the balance reaches zero, requests are rejected. There is no overdraft, no invoice, and no automatic charge.
• Credit does not expire while the account is open.

If you believe a charge is wrong, write to [email protected] within 60 days with the request ids. We will check the meter against our records and correct it if we were wrong.

6. Prices, taxes and payment

Prices and API credit amounts are shown in US dollars, excluding applicable tax. Paddle calculates any tax due from your billing details and shows the total before you pay. Tax is not added to your spendable API credit balance. Payments are handled by Paddle as merchant of record — the Paddle entity identified on your receipt is the seller and handles payment processing and applicable taxes. We never see or store your card details.

We may change prices with at least 30 days’ notice by email and on the site. A price change never applies retroactively to credit you have already bought.

7. Withdrawal and refunds

If you are a consumer in the EU you normally have 14 days to withdraw from a distance contract. Because credit is usable immediately, you are asked at checkout to consent to immediate performance; to the extent credit has been spent, the right of withdrawal is lost for that part, as EU law provides.

Independently of that: unused credit is refundable on request, at any time, to the payment method you used. Write to [email protected]. We refund within 14 days of agreeing the amount. We do not refund credit already converted into tokens you received.

8. Your content and your rights in it

Prompts, files, and completions stay yours. We claim no ownership of them and no licence to them beyond what is technically required to serve the request you sent. We do not train on them, and we do not store them — see the privacy notice for exactly what we do keep.

As between you and us, output is yours to use. Note that the underlying model licences still apply, and that identical output may be produced for someone else, so output is not guaranteed to be exclusive or protectable.

9. Availability, alpha status and changes

This is an alpha service. There is no uptime commitment yet and no service credits. Models sleep when idle. Cached restarts measured 65–67 seconds, but placement, migration and provider failures can cause much longer waits; no fixed wake time is promised.

We may add, change, or withdraw models. If a model you have used in the last 30 days is withdrawn, we will give at least 30 days’ notice by email, except where a licence change, a legal order, or a safety problem forces a faster removal.

10. Suspension and termination

You can close your account at any time and take the unused balance with you under section 7. We may suspend or close an account for breach of these terms or the acceptable-use policy, for non-payment of amounts due, or where we are legally required to. Except where the law or an active investigation prevents it, we tell you why, and we refund the unused balance.

11. Warranties and liability

The service is provided as-is. We do not warrant that output is accurate, safe, lawful in your jurisdiction, or fit for any purpose, and you must not rely on it as professional advice.

To the extent the law allows, our total liability arising out of the service is limited to the greater of the amount you paid us in the 12 months before the claim and the balance on your account. We are not liable for lost profits, lost data, or indirect loss. Nothing here limits liability for death or personal injury, for intentional damage or gross negligence, or any consumer right that cannot be waived.

You indemnify us against third-party claims arising from your use of the service in breach of these terms or the acceptable-use policy.

12. Changes to these terms

We will publish changes here and email account holders at least 30 days before material changes take effect. If you do not accept them, close the account before the effective date and take your unused balance.

13. Law and disputes

Czech law governs, and the Czech courts have jurisdiction — for consumers, without affecting your right to sue, and be sued, where you live. Consumers in Czechia may also take a dispute to the Czech Trade Inspection Authority (Česká obchodní inspekce, coi.cz) for out-of-court resolution.
