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.

Air Taxis: The Future of Urban Travel?

Joby Aviation and Virgin Atlantic Announce Partnership for Electric Air Taxi Service in the UK

Virgin Atlantic has announced a partnership with California-based Joby Aviation to launch an air taxi service in the UK, marking the latest move in the growing trend of electric aircraft vying to become the taxis of the sky. The partnership will allow customers to book a seat in one of Joby’s multi-rotor aircraft through the Virgin Atlantic website and app, with the vehicles featuring both companies’ logos.

How it Works

Joby’s all-electric aircraft has six rotors and seats five, including the pilot. The vehicle can take off vertically, like a helicopter, and then shift into forward flight using tilt rotors. According to Joby, the aircraft can reach a top speed of 200mph, travel 150 miles on a single battery charge, and is 100 times quieter than a conventional aircraft.

Regulatory Hurdles

Air taxi operators face several hurdles before they can become a reality, including safety regulations and airport designs. The UK’s Civil Aviation Authority has started looking into how airports would need to be reevaluated for air taxi flights, including charging and air space.

Future of Air Taxis

Joby and Virgin Atlantic envision 15-minute flights from Manchester Airport to Leeds, or 8-minute journeys from Heathrow Airport to Canary Wharf. Joby is planning a network of landing locations around the UK, and expects to offer prices that are comparable with "existing premium ground ridesharing options at launch."

The Competition

Air taxis, sometimes misidentified by the mainstream media as "flying cars," are essentially helicopters without the noisy, polluting gas motors (though they certainly have their own unique noise profile). In addition to Joby, companies like Archer Aviation, Volocopter, and Beta Technologies have claimed they are on the cusp of launching services that will eventually scale up nationwide. However, others have floundered; German company Lilium recently said that two of its subsidiaries were insolvent and could cease operations.

Joby’s Progress

Joby has made significant progress in completing four of the five stages required for commercial passenger service in the US, and expects to carry its first passengers late this year or early next. The company has also recently delivered a second aircraft to the US Air Force as part of a testing partnership.

Conclusion

The partnership between Joby and Virgin Atlantic marks an exciting step forward in the development of air taxis, but there are still many regulatory hurdles to overcome. As the industry continues to evolve, it will be important to closely monitor the progress of companies like Joby and others, as they work to bring this innovative mode of transportation to the masses.
