Stability AI Model License

This license sets out who can use Stability AI's models for free and who must pay. If your entire business earns less than USD $1M per year from any source, you can use and share the models at no charge; if you earn more, you may need to pay for an Enterprise License by contacting Stability AI directly. You own the outputs you create, but you must follow Stability AI's usage rules or risk losing your license.

The Stability AI Model License establishes a tiered access and licensing structure for Core Models and Derivative Works. Organizations with total annual revenue below USD $1M from any source may use and distribute Core Models and Derivative Works at no cost under the Community License; those exceeding USD $1M may be required to obtain a paid Enterprise License through direct contact with Stability AI. Research-only use is included within the Community License at no cost regardless of revenue, but commercial research use requires registration with Stability AI. Users own the outputs they generate as between themselves and Stability AI, and may use those outputs at their discretion subject to applicable law and Stability AI's Acceptable Use Policy, which also governs iterative fine-tuning workflows such as using LoRA outputs to train further LoRAs. Stability AI reserves the right to revoke the Community License upon violation of its terms.

An individual user or small organization with total annual revenue under USD $1M can use Core Models and Derivative Works, including iterative fine-tuning workflows, at no cost and owns the outputs they generate. That ownership applies as between the user and Stability AI and does not address any third-party claims. Output use is subject to applicable law and Stability AI's Acceptable Use Policy, and Stability AI can revoke the Community License for any violation of its terms. Users conducting research for a commercial purpose must register with Stability AI — that registration step is required for continued compliance.
