Summary

This is Stability AI's license agreement governing how users may access, deploy, and use Stability AI's generative AI models, including self-hosted options. The document establishes tiered licensing conditions, distinguishing between non-commercial and commercial use, with commercial licensing requiring a separate agreement for users or organizations exceeding specified revenue or deployment thresholds. The self-hosted model licensing structure authorizes users to run Stability AI models on their own infrastructure, subject to conditions set out in the applicable license tier.

Technical / Legal Breakdown

This document governs the licensing terms for Stability AI's generative AI models, including self-hosted deployment options, on the basis of a tiered commercial license structure. The agreement states conditions under which users may access, deploy, and build upon Stability AI models, with distinctions drawn between non-commercial, research, and commercial use cases requiring separate licensing agreements. The document's self-hosting license provisions and revenue-based thresholds for commercial licensing create operationally distinct eligibility conditions compared to purely API-based access models, though the full scope of these conditions cannot be confirmed from the truncated document text provided. Regulatory frameworks potentially engaged include the EU AI Act, which may impose transparency and conformity obligations on high-risk AI system deployments, as well as applicable consumer protection and intellectual property frameworks; the precise applicability of these frameworks depends on the jurisdiction of deployment and the use case category. Compliance teams should note that the bifurcation between open-access and commercially licensed model variants introduces data governance and downstream liability considerations that may require evaluation under applicable AI governance regulations.

What changed Stability AI removed two instances of 'Get in touch' call-to-action buttons from its Model License page on May 14, 2026. The first removal occurred in the Free license tier section, where one 'Get in touch' button was deleted. The second removal occurred in the Enterprise section, where a duplicate 'Get in touch' button was removed. These changes are formatting adjustments with no operational impact on license terms, pricing, features, or eligibility requirements.
Why this matters This change has no material impact on consumer terms or operations. The updated page removes redundant contact buttons but does not modify license terms, pricing, features, eligibility criteria, or support availability. Users seeking commercial licenses, enterprise solutions, or custom services can still request support through the remaining contact mechanisms.

Recent Provision Changes May 21, 2026

Added (3)
Tiered Commercial Licensing Requirement Medium

Introduction of a tiered licensing structure suggests Stability AI has implemented a more granular commercial monetization model with multiple licensing tiers based on revenue thresholds.

Non-Commercial and Research Use Carve-Out Low

New explicit carve-out for non-commercial and research uses clarifies that certain use cases are permitted without commercial licensing, potentially broadening accessibility for academic and non-profit entities.

Restrictions on Model Redistribution and Derivative Works Medium

New provision explicitly addresses control over redistribution and derivative works, indicating stricter IP protection measures compared to the previous version.

Removed (3)
Commercial Licensing Revenue Threshold

Removal of a specific revenue threshold provision suggests consolidation into the new 'Tiered Commercial Licensing Requirement', potentially making the licensing framework more flexible or variable.

Intellectual Property Ownership of Model Weights

Removal of explicit IP ownership provisions may indicate a shift in how model weight ownership is governed, possibly incorporated into other provisions or handled through separate agreements.

Downstream Use Restrictions and User Obligations

Removal of this standalone provision suggests these restrictions may have been redistributed among other provisions or refined into more specific limitation categories.

Modified (2)
Acceptable Use and Prohibited Content Restrictions

Provision was renamed from 'Acceptable Use Policy and Prohibited Content' to 'Acceptable Use and Prohibited Content Restrictions' and severity was reduced from high to medium, indicating a potential narrowing of enforcement scope.
