The Restrictive Landscape of AI Model Licensing
Confusion and Uncertainty in the AI Ecosystem
This week, Google released a family of open AI models, Gemma 3, which quickly garnered praise for their impressive efficiency. However, as a number of developers lamented on X, Gemma 3’s license makes commercial use of the models a risky proposition.
A Pattern of Restrictive Licensing
It’s not a problem unique to Gemma 3. Companies like Meta also apply custom, non-standard licensing terms to their openly available models, and the terms present legal challenges for companies. Some firms, especially smaller operations, worry that Google and others could "pull the rug" on their business by asserting the more onerous clauses.
The Open Source Initiative’s Concerns
"The restrictive and inconsistent licensing of so-called ‘open’ AI models is creating significant uncertainty, particularly for commercial adoption," said Nick Vidal, head of community at the Open Source Initiative, a long-running institution aiming to define and "steward" all things open source. "While these models are marketed as open, the actual terms impose various legal and practical hurdles that deter businesses from integrating them into their products or services."
Reasons for Restrictive Licensing
Open model developers have their reasons for releasing models under proprietary licenses as opposed to industry-standard options like Apache and MIT. AI startup Cohere, for example, has been clear about its intent to support scientific — but not commercial — work on top of its models.
Gemma and Meta’s Licenses
Gemma and Meta’s Llama licenses, in particular, have restrictions that limit the ways companies can use the models without fear of legal reprisal. Meta, for instance, prohibits developers from using the "output or results" of Llama 3 models to improve any model besides Llama 3 or "derivative works." It also prevents companies with over 700 million monthly active users from deploying Llama models without first obtaining a special, additional license.
Gemma’s License
Gemma’s license is generally less burdensome. However, it grants Google the right to "restrict (remotely or otherwise) usage" of Gemma that Google believes is in violation of the company’s prohibited use policy or "applicable laws and regulations."
Consequences for the AI Ecosystem
These terms don’t just apply to the original Llama and Gemma models. Models based on Llama or Gemma must also adhere to the Llama and Gemma licenses, respectively. In Gemma’s case, that includes models trained on synthetic data generated by Gemma.
A Call to Action
"Most companies have a set of approved licenses, such as Apache 2.0, so any custom license is a lot of trouble and money," said Florian Brand, a research assistant at the German Research Center for Artificial Intelligence. "Small companies without legal teams or money for lawyers will stick to models with standard licenses."
Conclusion
The current landscape of AI model licensing is riddled with confusion, restrictive terms, and misleading claims of openness. The AI industry should align with established open source principles to create a truly open ecosystem.
