Terms of Use

Acceptance of these terms

These Terms of Use ("Terms") are a binding agreement between you and Keln Inc. ("Keln," "we," "us") governing your access to and use of the keln.ai website (the "Site") and the inference services we provide (together, the "Services"). By accessing the Site or using the Services, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Services.

The Services

Keln provides inference for open-weight large language models behind one OpenAI-compatible endpoint. We route each request in real time across a fleet of independent compute providers, enforce quality and integrity, and normalize provider differences so responses are consistent. Features, models, pricing, throughput targets, and supported regions may change at any time without notice.

Eligibility

You must be at least 16 years old and capable of forming a binding contract in your jurisdiction to use the Services. If you use the Services on behalf of an organization, you represent that you have authority to bind that organization to these Terms, and "you" refers to both you and that organization.

Acceptable use

You agree not to, and not to permit others to:

• Use the Services to violate any law or the rights of others.
• Send content that is illegal, infringing, defamatory, or that depicts the sexual abuse of minors.
• Generate content intended to harass, defraud, or impersonate a real person.
• Produce malware, phishing content, or other material designed to compromise systems or credentials.
• Use output to develop a competing large language model, or to reverse-engineer the weights or architecture of any model served by Keln.
• Attempt to bypass rate limits, access controls, or security measures, or to probe or disrupt the infrastructure.
• Resell, redistribute, or sublicense access to the Services except as we have authorized in writing.

We may suspend or terminate access, with or without notice, if we reasonably believe you have breached these Terms or that continued access poses a risk to Keln, other users, providers, or third parties.

Compute providers

Keln serves inference using capacity from independent compute providers. Keln remains your sole counterparty for the Services: you contract with Keln, are billed by Keln, and receive Keln's reliability and integrity guarantees. Providers serve requests on our behalf, never receive your identity or brand, and operate zero data retention as stated in their own policies, which we monitor on an ongoing basis. Keln admits, ranks, and removes providers at its discretion to meet quality and integrity standards.

If you participate as a provider, the For providers section below applies to that relationship in addition to these Terms.

Your content and prompts

You retain all rights in the prompts you submit and the completions the Services produce for you ("Your Content"). You grant Keln a limited, non-exclusive license to process Your Content only as needed to operate the Services and to meet our legal obligations.

We do not train models on Your Content and we do not retain prompts or completions beyond what is required to serve the request. You are responsible for ensuring that Your Content does not infringe the rights of any third party and that you have all rights necessary to submit it.

Model outputs are generated from statistical patterns and can be inaccurate, offensive, or misleading. You are responsible for reviewing outputs before relying on them, and the Services must not be used as the sole basis for decisions with legal, medical, financial, or safety consequences.

Fees and payment

You agree to pay all fees for your use of the Services at the prices then in effect, and you authorize us or our payment processor to charge your selected payment method. Prepaid credits and amounts already paid are non-refundable except where required by law. Fees are exclusive of taxes, and you are responsible for any applicable taxes other than taxes on Keln's net income. We may change prices prospectively; a change does not affect credits already purchased. If a payment fails or an amount is overdue, we may suspend or limit your access until it is resolved.

Intellectual property

The Site, the Keln name and marks, and all software, documentation, and designs made available by Keln are owned by Keln or its licensors and are protected by intellectual property laws. Except for the limited right to use the Services in accordance with these Terms, no license is granted to you. Open-weight models served through the Services are licensed to you by their respective licensors under the licenses that accompany them; you are responsible for complying with those licenses.

Feedback

If you send Keln any suggestions, bug reports, benchmarks, or other feedback about the Services ("Feedback"), you grant Keln a perpetual, royalty-free, worldwide license to use it for any purpose, without attribution or confidentiality. Feedback is non-confidential, and Keln is not obligated to act on it.

Performance and availability

Latency, throughput, success-rate, and availability figures shown on the Site describe target or typical performance under measured conditions and are not commitments unless set out in a separate written agreement. Actual performance depends on factors including model, request size, concurrency, and geography. The Services may be unavailable during maintenance windows, capacity events, or incidents, and we do not warrant uninterrupted operation.

Disclaimers

THE SERVICES, THE SITE, AND ALL MODEL OUTPUTS ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, AND UNINTERRUPTED OR ERROR-FREE OPERATION. NO ORAL OR WRITTEN INFORMATION OR ADVICE GIVEN BY KELN CREATES A WARRANTY NOT EXPRESSLY STATED IN THESE TERMS.

IP infringement disclaimer

Keln serves third-party and open-weight models whose training data we did not produce. Outputs may, in rare cases, resemble or reproduce material in which a third party claims rights. Keln does not pre-screen outputs and makes no warranty that they are free of third-party IP claims, and provides no defense, indemnity, or "copyright shield" for outputs.

You are responsible for reviewing outputs and clearing any rights that apply to your use. If you believe an output infringes your rights, contact us at contact@keln.ai and we will review the report in good faith.

Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, KELN AND ITS OFFICERS, EMPLOYEES, AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUES, DATA, OR GOODWILL, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICES, WHETHER BASED ON WARRANTY, CONTRACT, TORT, OR ANY OTHER LEGAL THEORY, AND WHETHER OR NOT KELN HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

KELN'S TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICES WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS PAID BY YOU TO KELN FOR THE SERVICES IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS (US$100).

Indemnification

You agree to defend, indemnify, and hold harmless Keln and its officers, employees, and agents from any claim, liability, loss, or expense (including reasonable attorneys' fees) arising from (i) Your Content, (ii) your use of the Services in violation of these Terms or applicable law, or (iii) your violation of the rights of any third party.

Export controls and sanctions

You represent that you are not located in, and will not use the Services in or for the benefit of, any country or region subject to comprehensive U.S. sanctions, and that you are not identified on any U.S. government restricted-party or denied-party list. You agree to comply with all applicable export control and sanctions laws when using the Services, and not to use the Services to develop or support any activity those laws prohibit.

Suspension and termination

We may suspend, limit, or terminate your access to the Services at any time if we reasonably believe that you have breached these Terms, that continued access presents a legal or security risk, or that we are required to do so by law. You may stop using the Services at any time. Sections that by their nature should survive termination (including Your content and prompts, Fees and payment, Intellectual property, Disclaimers, IP infringement disclaimer, Limitation of liability, Indemnification, Export controls and sanctions, the zero-data-retention and indemnity obligations under For providers, Dispute resolution and arbitration, Governing law, and General) will survive.

For providers

This section applies only if you register with Keln as a compute provider (a "Provider"). It is in addition to the rest of these Terms, and where it conflicts with the rest of these Terms as applied to your provider activity, this section controls.

Serving requests. As a Provider, you make compute capacity available to serve inference requests that Keln routes to you. You agree to serve the model and weights requested, without silent substitution, quantization, or modification, and to meet the quality, latency, and integrity standards Keln sets. Keln may admit, rank, throttle, suspend, or remove Providers at its discretion.

Zero data retention. You must process each request in memory only. You will not store, log, cache to disk, transmit, or otherwise retain prompt or completion content, will not use it to train or improve any model, and will not attempt to identify, profile, or contact Keln's users. This obligation is a condition of serving requests and survives termination.

Security and compliance. You will keep your infrastructure secure, will not tamper with, inspect, or exfiltrate request content, and will comply with all applicable laws, including export control and sanctions laws.

Payment. Keln pays you for the capacity you serve at the rate shown or agreed in your Provider dashboard. Earnings accrue to your balance, and you may withdraw available amounts weekly, subject to identity and tax verification. You are responsible for providing accurate payout and tax details (such as a W-9 or W-8) and for all taxes on your earnings. Keln may withhold, offset, or reverse amounts for fraud, chargebacks, disputed usage, or your breach of these Terms.

Representations. You represent that you have the right and authority to provide the capacity, that your infrastructure meets the zero-retention and security obligations above, and that you serve models under licenses that permit your use.

Independent relationship. You are an independent contractor. Nothing here creates an employment, partnership, agency, or joint-venture relationship between you and Keln.

Provider indemnity. In addition to the Indemnification section above, you will defend, indemnify, and hold Keln harmless from any claim, liability, loss, or expense arising from your breach of this For providers section, including any failure to meet the zero-data-retention or security obligations.

Dispute resolution and arbitration

Please read this section carefully. It affects how disputes between you and Keln are resolved.

Informal resolution first. Before starting an arbitration, you agree to email us at contact@keln.ai and attempt to resolve the dispute informally for at least 30 days.

Binding arbitration. Except for the carve-outs below, any dispute arising out of or relating to these Terms or the Services will be resolved by final and binding arbitration administered by the American Arbitration Association ("AAA") under its Commercial Arbitration Rules. The arbitration will be seated in San Francisco County, California, and may proceed by written submissions or video where the rules allow. Judgment on the award may be entered in any court of competent jurisdiction.

Class-action waiver. Disputes will be resolved only on an individual basis. You and Keln each waive any right to bring or participate in a class, collective, consolidated, or representative action, and the arbitrator may not consolidate more than one person's claims.

Carve-outs. Either party may bring a claim in small-claims court, and either party may seek injunctive or other equitable relief in court to protect its intellectual property or confidential information.

Opt-out. You may opt out of this arbitration agreement within 30 days of first accepting these Terms by emailing contact@keln.ai with your account details and a clear statement that you opt out. If you opt out, the Governing law section below governs your disputes instead.

Governing law and disputes

These Terms are governed by the laws of the State of California, without regard to its conflict-of-laws rules. For any dispute not subject to arbitration under the section above, the state and federal courts located in San Francisco County, California, have exclusive jurisdiction, and you consent to their jurisdiction and venue. The U.N. Convention on Contracts for the International Sale of Goods does not apply.

Changes to these Terms

We may update these Terms from time to time. When we make material changes we will update the "Last updated" date above and, where appropriate, notify you by email or through the Site. Your continued use of the Services after an update means you accept the revised Terms.

General

These Terms, together with the Privacy Policy, are the entire agreement between you and Keln about the Services and supersede any prior understandings. If any provision is held unenforceable, the rest remains in effect and the unenforceable provision is limited to the minimum extent necessary. Our failure to enforce a provision is not a waiver of it. You may not assign these Terms without our prior written consent; we may assign them to an affiliate or in connection with a merger, acquisition, or sale of assets. Neither party is liable for delays or failures caused by events beyond its reasonable control.
