OpenRouter added a link to "Benchmarks" in the footer navigation of their Terms of Service page, detected on August 12, 2026. The updated footer now includes this new link alongside existing navigation items like Chat, Rankings, and Apps. This is a navigation and product menu update with no change to the substantive terms, policies, or user obligations.

OpenRouter's Terms of Service were updated in an update detected on August 11, 2026. The change added "Developer Platform" to the navigation footer alongside existing links like "Status" and "API Reference". This reflects a structural update to the document's footer navigation and does not modify substantive terms governing user rights, obligations, or service conditions.

OpenRouter added detailed provisions governing API credentials, promotional credits, and credit management in an update detected on August 5, 2026. The revised terms establish that users are responsible for all activity under their API credentials except where caused by OpenRouter's breach, require notification of suspected unauthorized access, and permit OpenRouter to suspend or revoke credentials if reasonably necessary to protect the service. The terms also clarify that promotional credits have no cash value, expire on specified dates, are non-transferable, and are subject to different refund rules than purchased credits.

OpenRouter restructured its User Content storage terms detected on July 28, 2026. Previously, the agreement described only Private Prompt Storage (opt-in) and general content licensing; the updated terms now distinguish three storage categories: opt-in Private Prompt Storage for debugging, processing-related temporary storage for batch/large-volume requests with specific access limitations, and feature-specific retention periods documented separately. Users grant OpenRouter a license to host and store content for processing purposes under the new section, with OpenRouter limited to accessing such content only as necessary to operate, secure, troubleshoot the service, or comply with law.

OpenRouter's Terms of Service page was updated in an update detected on July 25, 2026. Two minor changes were made: the navigation header and footer were reorganized, with the addition of 'Discover' preceding 'Models' in the footer link structure. These are formatting and navigation adjustments with no material change to the substantive terms of service.

OpenRouter removed the phrase 'State of AI' from their contact and navigation information in the Terms of Service document, detected on July 21, 2026. This appears to be a minor editorial or organizational change affecting the footer navigation. The operational substance of the Terms of Service itself remains unchanged.

OpenRouter updated its Terms of Service on July 19, 2026, changing the contact email address for customer support, account security concerns, model terms issues, and account termination from [email protected] to support@openrouter.ai. Additionally, the document added navigation links for 'Sign Up' to the header. These are administrative updates to contact information; the substantive rights and obligations stated in the terms remain unchanged.

OpenRouter removed markup indicating external links (the 'opens in new tab' notation) from ten locations throughout their Terms of Service, detected on July 14, 2026. The substantive terms and policies remain unchanged; only the visual/technical indicators showing where links direct to external pages were deleted. This is a formatting and presentation change with no impact on the rights, obligations, or disclosures described in the terms.

OpenRouter updated its Terms of Service on July 7, 2026, with the most material change being clarification and reorganization of user content licensing provisions. The updated terms now explicitly state that if users opt into prompt logging, chat logging is automatically enabled, and OpenRouter receives a broad license to use user content for service provision and commercial purposes, including licensing or selling anonymized content. The terms also introduced a new reference to a Stealth Program End User License Agreement for users accessing models in that program. Several sections were reorganized and minor grammatical corrections were made, but the core substantive permissions regarding content licensing and data handling remain substantially similar to previous language.

OpenRouter updated their Terms of Service header on June 23, 2026, adding a Search function indicator (⌘ K) to the navigation menu. This is a minor interface change in how the document presents itself rather than a substantive modification to the terms themselves. The operational difference is negligible—users now see a search feature available in the header, but no policy, obligation, or right has changed.

OpenRouter's Terms of Service header was updated on May 24, 2026 to display 'No models found' in the navigation area where 'Models' previously appeared. This appears to be a technical or interface change in how the document is displayed rather than a substantive modification to the legal terms themselves. The actual terms of service text and 'Last Updated' date remain unchanged.

OpenRouter corrected a typographical error in its restriction on accessing Restricted Models, changing 'will now allow' to 'will not allow' in the usage restrictions clause. The updated language now correctly states that users agree not to allow their Authorized Users or customers to use the Service to access Restricted Models through circumvention methods. Additionally, the document underwent organizational restructuring, with cross-references updated from Section 18 to Section 19 in the liability limitation clause, reflecting a renumbering of the terms document.
