The open-source model – a software development ethos in which source code is made freely available for public redistribution or modification – has long been a catalyst for innovation. The ideal was born in 1983 when Richard Stallman, a software developer, became frustrated with the black box nature of his closed-source printer on the fritz.
His vision sparked the free software movement, paving the way for the open-source ecosystem that powers much of today's internet and software innovation.
But that was over 40 years ago.
Today, Generative AI, with its unique technical and ethical challenges, is reshaping the meaning of “openness,” demanding that we revisit and rethink the open-source paradigm – not to abandon it, but to adapt it.
AI and the Open-Source Freedoms
The four fundamental freedoms of open-source software – the ability to run, study, modify, and redistribute any software code – are at odds with the nature of generative AI in several ways:
- Run: AI models often require very high infrastructure and computational costs, which limit access due to resource constraints.Study and modify: AI models are incredibly complex, so understanding and altering them without access to both the code and the data that informs it is a significant challenge.Redistribution: Many AI models restrict redistribution by design, particularly those with trained weights and proprietary datasets owned by the platform provider.
The erosion of these core tenets is not due to malicious intent but rather the sheer complexity and cost of modern AI systems. Indeed, the financial demands of training state-of-the-art AI models have escalated dramatically in recent years – OpenAI's GPT-4 reportedly incurred training costs of up to $78 million, excluding staff salaries, with total expenditures exceeding $100 million.
The Complexity of “Open Source” AI
A truly open AI model would require total transparency of inference source code, training source code, model weights, and training data. However, many models labeled as “open” will only release inference code or partial weights, while others offer limited licensing or restrict commercial usage altogether.
This impartial openness creates the illusion of open-source principles, while falling short in practice.
Consider that an analysis by the Open Source Initiative (OSI) found that several popular large language models claiming to be open source – including Llama2 and Llama 3.x (developed by Meta), Grok (X), Phi-2 (Microsoft), and Mixtral (Mistral AI) – are structurally incompatible with open-source principles.
Sustainability and Incentivization Challenges
Most open-source software was built on volunteer-driven or grant-funded efforts, rather than compute-intensive, high-cost infrastructures. AI models, on the other hand, are expensive to train and maintain, and costs are only expected to rise. Anthropic's CEO, Dario Amodei, predicts that it could eventually cost as much as $100 billion to train a cutting-edge model.
Without a sustainable funding model or incentive structure, developers face a choice between restricting access through closed-source or non-commercial licenses or risking financial collapse.
Misconceptions Around “Open Weights” and Licensing
AI model accessibility has become increasingly muddled, with many platforms marketing themselves as “open” while imposing restrictions that fundamentally contradict true open-source principles. This “sleight-of-hand” manifests in multiple ways:
- Models labelled as “open weights” may prohibit commercial use entirely, maintaining them more as academic curiosities than practical business tools for the public to explore and develop.Some providers offer access to pre-trained models but zealously guard their training datasets and methodologies, making it impossible to reproduce or verify their findings meaningfully.Many platforms impose redistribution restrictions that prevent developers from building upon or improving the models for their communities, even if they can fully “access” the code.
In these instances, “open for research” is just doublespeak for “closed for business.” The result is a disingenuous form of vendor lock-in, where organizations invest time and resources into platforms that appear openly accessible, only to discover critical limitations when attempting to scale or commercialize the applications.
The resulting confusion doesn't merely frustrate developers. It actively undermines trust in the AI ecosystem. It sets unrealistic expectations among stakeholders who reasonably assume that “open” AI is comparable to open-source software communities, where transparency, modification rights, and commercial freedom are upheld.
Legal Lag
GenAI’s rapid advancement is already outpacing the development of appropriate legal frameworks, creating a complex web of intellectual property challenges that compound preexisting concerns.
The first major legal battleground centers on the use of training data. Deep learning models source large data sets from the Internet, such as publicly available images and the text of web pages. This massive data collection has ignited fierce debates about intellectual property rights. Tech companies argue that their AI systems study and learn from copyrighted materials in order to create new, transformative content. Copyright owners, however, contend that these AI companies unlawfully copy their works, generating competing content that threatens their livelihoods.
Ownership of AI-generated derivative works represents yet another legal ambiguity. No one is quite sure how to classify AI-generated content, except for the U.S. Copyright Office, which states that “if AI entirely generates content, it cannot be protected by copyright.”
The legal uncertainty surrounding GenAI – particularly regarding copyright infringement, ownership of AI-generated works, and unlicensed content in training data – becomes even more fraught as foundational AI models emerge as tools of geopolitical importance: Nations racing to develop superior AI capabilities may be less inclined to restrict data access, putting countries with stricter IP protections at a competitive disadvantage.
What Open Source Must Become in the AI Age
The GenAI train has already left the station and shows no signs of slowing. We hope to build a future where AI encourages rather than stifles innovation. In that case, tech leaders need a framework that ensures safe and transparent commercial use, promotes responsible innovation, addresses data ownership and licensing, and differentiates between “open” and “free.”
An emerging concept, the Open Commercial Source License, may offer a path forward by proposing free access for non-commercial use, licensed access for commercial use, and acknowledgment of and respect for the provenance and ownership of data.
To adapt to this new reality, the open-source community must develop AI-specific open licensing models, form public-private partnerships to fund these models, and establish trusted standards for transparency, safety, and ethics.
Open source changed the world once. Generative AI is changing it again. To preserve the spirit of openness, we must evolve the letter of its law, acknowledging the unique demands of AI while addressing the challenges head-on to create an inclusive and sustainable ecosystem.
