Stability AI Model License

This document governs the licensing terms for Stability AI's generative AI models, specifically addressing self-hosted deployment options and the conditions under which users and organizations may access, use, and redistribute Stability AI's open model weights. The terms authorize non-commercial use under a community license and require a paid enterprise license for commercial deployment above specified revenue thresholds, with the agreement asserting that any organization generating more than a defined annual revenue must obtain a separate commercial license to use the models. The self-hosted license structure is operationally distinct from typical API-only AI service agreements in that it permits local model deployment while imposing downstream use restrictions, acceptable use policy obligations, and prohibitions on specific harmful outputs including CSAM, weapons-related content, and content designed to deceive. The document engages intellectual property frameworks including copyright and trade secret law, and the commercial licensing threshold structure may require evaluation under competition and consumer protection frameworks in the EU and US; applicability of the EU AI Act to downstream deployers using self-hosted Stability AI models creates a compliance consideration that depends on the deployer's jurisdiction and use case. Material compliance considerations include whether downstream commercial deployers have properly licensed the models, how acceptable use policy violations are monitored and enforced in a self-hosted context, and how AI-generated output liability is allocated between Stability AI and the deploying entity.
