OpenRouter's Acceptable Use Policy sets out the rules for using its AI model routing platform, covering what types of content and applications are permitted or prohibited across all models accessible through the service. The policy states that users and operators building applications on OpenRouter are prohibited from using the platform to generate content involving child sexual abuse material, weapons of mass destruction, unlawful surveillance, or systematic deception, and that operators are responsible for ensuring their end users comply with these restrictions. The policy also incorporates by reference the terms of individual upstream AI model providers, meaning that users may be subject to additional restrictions depending on which model they access through the platform.
This document is OpenRouter's Acceptable Use Policy, which governs permissible and prohibited uses of the OpenRouter platform, an API-based service that routes requests to third-party AI model providers. The terms establish categories of prohibited content and conduct, including prohibitions on generating content that facilitates illegal activity, produces CSAM, enables weapons development, or engages in systematic deception, and the agreement states that users are responsible for ensuring their applications comply with both OpenRouter's policy and the upstream model providers' terms of use. The policy is operationally notable in that it applies not only to direct API users but also to downstream applications built on the platform, creating a layered compliance obligation where operators bear responsibility for their end users' conduct. The document engages general consumer protection frameworks, AI governance considerations, and content moderation obligations that may interact with the EU AI Act, GDPR for EU-based users, and sector-specific regulations depending on the use case. Compliance teams deploying OpenRouter in regulated industries should evaluate whether the upstream model provider terms create additional constraints that are incorporated by reference into the user's obligations under this policy.
