🧠 Training & Data Policy
For self-hosted models, Stability AI has no access to your data. For the API, Stability AI's standard terms may allow limited data use for service improvement. Enterprise plans offer explicit data isolation guarantees.
Stable Diffusion's terms prohibit:
- No illegal or harmful content generation
- No non-consensual intimate imagery
- No content to build competing foundational AI models
- No misrepresentation of AI outputs as human-created
- Use-based restrictions propagate to derivative works
🏛️ Copyright & Legal Status
While Stable Diffusion's terms grant you ownership and commercial rights, the broader question of copyright protection for AI-generated content remains legally unsettled.
Under current U.S. Copyright Office guidance and the 2025 D.C. Circuit ruling in Thaler v. Perlmutter, purely AI-generated content cannot be copyrighted because it lacks the human authorship required by copyright law. This means:
- You can use outputs commercially — the platform grants you this right contractually
- You may not be able to stop copying — without copyright, others can freely reproduce AI-generated content
- Human contribution matters — if you substantially edit, direct, or transform AI outputs, your human creative contributions may qualify for copyright protection
- International variation — some jurisdictions (e.g., China) have begun recognizing copyright in sufficiently human-directed AI outputs
For maximum legal protection: (1) Use Stable Diffusion outputs as a starting point and add substantial human editing, (2) Keep records of your creative direction and editing process, (3) Consider the API or paid tiers for stronger data protection, (4) Consult an attorney for high-value commercial applications.
❓ Frequently Asked Questions
Yes. All versions of Stable Diffusion permit commercial use of generated images. For older models (SD 1.5, SDXL) under the CreativeML Open RAIL-M license, there are no revenue limits. For newer models (SD 3, 3.5), the Community License is free for organizations under $1M annual revenue; above that, an Enterprise license is required.
It's a permissive license that allows commercial use, modification, and redistribution of both the model and its outputs. The 'RAIL' stands for Responsible AI License -- it includes use-based restrictions (no illegal content, no harmful applications) but no revenue caps or royalty requirements. It applies to SD 1.5, SD 2.1, and SDXL.
No. Your ownership and commercial rights are identical whether you run Stable Diffusion on your own hardware or access it through Stability AI's API. The deployment method affects convenience and cost, not your IP rights.
Under current U.S. law, purely AI-generated images cannot be copyrighted because they lack human authorship. However, if you provide substantial creative direction (detailed prompting, img2img editing, inpainting, compositing), your human contributions may qualify for copyright protection.
Stable Diffusion 3 and 3.5 use a Community License that's free for commercial use if your organization generates under $1M in annual revenue from any source. Above $1M, you need a Professional ($20/mo) or Enterprise license. Older models (SD 1.5, SDXL) have no such threshold.
SD 1.5 and SDXL are released under the CreativeML Open RAIL-M license, which is very permissive but not technically 'open source' under the OSI definition due to its use-based restrictions. SD 3/3.5 use a more restrictive Community License with the revenue threshold. The model weights are freely downloadable for all versions.
Yes. You can integrate Stable Diffusion into commercial products and services. For SD 1.5/SDXL, there are no restrictions. For SD 3/3.5, ensure your organization's total revenue stays under $1M for the free Community License, or obtain a Professional/Enterprise license.
Stable Diffusion offers more flexibility: you can self-host (no API dependency), older models have no revenue limits, and the CreativeML license is more permissive. Midjourney requires paid subscription for commercial use and has a $1M revenue threshold for its basic plan. SD gives you more control but requires more technical setup.
