Guardians supervise minors and legal limits constrain the disclaimer
Minors should review the terms with a guardian and use the service under guardian guidance. Z.ai says its protective measures cannot ensure control of minors’ use and disclaims responsibility for minors’ violations or harm from their actions or lack of supervision. The liability section preserves applicable local-law limits and additional rights. This does not itself establish an age-based eligibility rule.
Supporting quotations
Minor protection and liability disclaimer. You acknowledge and agree that, despite our implementation of comprehensive measures to protect minors, we cannot fully guarantee that their use of this Service will always be controlled due to technical limitations, intentional misuse, or improper use by users. We bear no legal responsibility for any violations of laws, these Terms, or Platform Rules by minors, nor for any loss or harm resulting from a minor’s actions or a guardian’s failure to provide proper supervision. We strongly recommend that minors use this service under the guidance of their guardians, who are responsible for supervising their activities.
Jurisdictional variations. Some jurisdictions do not allow certain warranty disclaimers or limitations on liability. In such cases, the limitations set forth in this section will apply only to the maximum extent permitted by the laws of your country or state of residence, and you may have additional rights under local law.
Please ensure that you carefully read and fully understand all the terms and conditions herein. These Terms, along with our Privacy Policy, guidelines, rules, interpretations, announcements, notices, and other content that have been published or may be published in the future by Z.ai (“Platform Rules”), constitute the terms and conditions you must adhere to when using Z.ai. If you are a minor under the laws of your country or state of residence, you should review these Terms with your legal guardian.

Service changes have differing notice formulations
Z.ai reserves the right to discontinue, suspend or modify services at any time and says it may give advance notice where reasonably practicable. Elsewhere it promises prompt notice for service changes that may affect rights and the general updates clause promises at least 30 days’ advance notice. These differing formulations do not establish one clear notice period for every discontinuation.

Service Discontinuation. We reserve the right to discontinue, suspend or modify the Services at any time, and may provide you with prior notice where reasonably practicable.
You have the right to use the Services provided by the Z.ai in accordance with the terms and conditions of these Terms and Platform Rules. As generative artificial intelligence technology, models, and products continue to evolve, along with changes in laws and regulations, we may add, upgrade, modify, suspend, or terminate services, or make necessary adjustments to the technology, method, and performance of the Services. If such changes may affect your rights, we will promptly notify you through in-site notifications, website announcements, or via email. If you continue to use the Services after the changes, it indicates your acceptance of the adjusted service content.
We will notify you of these changes by updating our website, sending an email, or using other appropriate communication methods with at least 30 days advance notice.
Cross-references
contrast (model-proposed): The general update clause promises 30 days’ advance notice — contrast: The discontinuation clause says advance notice may be given where reasonably practicable, while the general update clause promises at least 30 days. The cards preserve both notice formulations without claiming a single clear period for every discontinuation.

Services can change or end as technology and laws evolve
Z.ai may add, upgrade, modify, suspend or terminate services or adjust their technology, method and performance as technology and laws evolve. It promises prompt notice when changes may affect rights, while the general updates clause promises 30 days’ advance notice and the discontinuation clause says advance notice may be given where reasonably practicable. The document does not reconcile these notice formulations. Continued use signals acceptance, subject to the terms and Platform Rules.
