If you create and share a modified version of Llama 3, you must include the phrase 'Built with Meta Llama 3' in its documentation but cannot use the name 'Llama' or Meta's trademarks in the product name without Meta's written permission.
This analysis describes what Meta's agreement states, permits, or reserves. It does not constitute a legal determination about enforceability. Regulatory applicability and practical outcomes may vary by jurisdiction, enforcement context, and individual circumstances. Read our methodology
This clause creates dual obligations for derivative model creators: a mandatory attribution requirement and a trademark restriction, meaning licensees must affirmatively identify their work as Llama-derived while simultaneously being prohibited from using Llama branding in product names without consent.
Developers releasing modified versions of Llama 3 must include 'Built with Meta Llama 3' attribution in their README documentation, which creates a visible disclosure of the model's origins for downstream users and developers who rely on that derivative model.

"If you create derivative works or modifications based on Llama 3, you will not use the name 'Llama' or any other Meta trademark without prior written consent from Meta. If you create derivative works or modifications based on Llama 3 and distribute or make available such derivative works or modifications to third parties, you will add to such derivative works or modifications the following attribution in the relevant README: 'Built with Meta Llama 3'.— Excerpt from Meta's Llama Community License Agreement
(1) REGULATORY LANDSCAPE: Trademark law governs the restriction on using the 'Llama' name, and violations would be actionable under the Lanham Act in the US and equivalent trademark statutes in other jurisdictions. The EU AI Act's transparency requirements for general-purpose AI models may independently require disclosure of the underlying model used, potentially overlapping with this attribution requirement. (2) GOVERNANCE EXPOSURE: Low to Medium. The attribution requirement is operationally straightforward for organizations maintaining standard documentation practices, but the trademark restriction requires IP review of any product naming decisions involving derivative models. (3) JURISDICTION FLAGS: Trademark enforcement varies by jurisdiction; the restriction on using 'Llama' branding applies globally under the agreement but the practical enforcement of trademark rights depends on Meta's trademark registrations in specific countries. (4) CONTRACT AND VENDOR IMPLICATIONS: Organizations distributing derivative models to enterprise clients should ensure that client-facing documentation, model cards, and technical specifications include the required attribution. B2B contracts involving derivative model distribution should reference this obligation to ensure downstream compliance. (5) COMPLIANCE CONSIDERATIONS: IP and product teams should implement a review process for all derivative model releases to confirm attribution text is present in README files and that product names do not incorporate 'Llama' or other Meta trademarks without written consent.
