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 large language models on its own infrastructure. Today, inference is offered primarily through third-party aggregators such as OpenRouter; direct access may be made available in the future. 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 a company or other 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.
• Use the Services to produce malware, phishing content, or other material designed to compromise systems or credentials.
• Use the output of the Services 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 raw access to the Services except through an aggregator or reseller we have authorized.

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, or third parties.

Third-party aggregators

When you access Keln-served models through a third-party aggregator (such as OpenRouter), that aggregator has its own terms, privacy policy, and billing arrangement with you. Keln is not responsible for the acts or omissions of any aggregator, and nothing in these Terms creates an agency or partnership between Keln and any aggregator. In the event of a conflict between the aggregator's terms and these Terms with respect to Keln's role, these Terms control for matters concerning the Keln-served inference.

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.

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-source 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 & availability

Latency, throughput, and availability figures shown on the Site describe target or typical performance under measured conditions and are not commitments. Actual performance depends on factors including model, request size, concurrency, geography, and the routing behavior of the aggregator you use. 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-source 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 kris@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.

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 Content, Intellectual Property, Disclaimers, Limitation of Liability, Indemnification, and Governing Law) will survive.

Governing law & disputes

These Terms are governed by the laws of the State of California, without regard to its conflict-of-laws rules. The state and federal courts located in San Francisco County, California, have exclusive jurisdiction over any dispute that is not subject to arbitration, 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.
