The Open Source Initiative (OSI) has rolled out a new standard defining open-source AI, aiming to clarify what it means for AI models to be accessible, modifiable, and free to use under OSI-approved terms. Known as the Open Source AI Definition (OSAID), this guideline sets benchmarks for transparency, unrestricted access, and adaptability. The release of this definition follows mounting criticism from OSI and industry experts over companies such as Meta, which markets its LLaMA models as “open source” despite imposing restrictions that many argue conflict with open-source principles.
OSI’s AI Definition: Setting the Standard for Transparency and Access
According to the OSI’s definition, for an AI model to be considered genuinely open source, it must offer unrestricted use, modification, and distribution rights, along with transparent disclosures about training data and model architecture. OSI executive Stefano Maffulli, emphasizing the importance of this initiative, noted, “If we’re going to call AI open source, it has to be done with full transparency — no hidden data or constraints on how it’s used.” By providing clear terms, the OSI hopes to align AI development with traditional open-source software principles, where transparency and user autonomy are essential.
Maffulli has explained that, though the OSI cannot enforce these standards, they aim to empower the AI community to reject models that don’t adhere to OSAID. OSI hopes that community-driven pressure will help keep companies accountable for claims around open-source AI. Maffulli noted that, without clear standards, companies can exploit the term to market products while limiting user control, diluting the open-source movement’s original intent.
Meta’s “Open Source” LLaMA Models and the Licensing Dispute
Meta’s AI models, particularly LLaMA, have recently come under fire for how they use the “open source” label. Though widely downloaded and promoted as open-source, LLaMA’s licenses restrict commercial usage and require platforms with large user bases to seek additional permissions. These restrictions, argue critics like OSI’s Maffulli, compromise the core open-source values, raising questions over whether Meta’s labeling is misleading.
In response, Meta has defended its licensing approach, citing safeguards against potential misuse. However, industry experts such as Ali Farhadi from the Allen Institute for AI suggest that “open-weight” might be a more fitting description. Farhadi contends that, while Meta provides access to certain model components, it restricts full adaptability and independent modification, which fall short of the freedoms central to open-source software.
Matt Asay, a well-known voice in open-source licensing and industry veteran, points out that “AI’s open-source journey is unlike any we’ve seen,” as the technology’s dependence on vast, proprietary datasets changes the equation. “Traditional open-source means you have access to the entire mechanism,” Asay explained, “but in today’s AI, developers often can’t see, let alone access, the training data. This is a core issue that Meta’s LLaMA faces — the label ‘open-source’ doesn’t work the same way here.” Asay’s observation underscores the unique challenges of applying the open-source model to AI, where closed data practices often contradict open-source claims.
Regulatory Pressure for Transparent AI Practices
The OSI’s initiative has arrived as regulatory bodies like the European Commission are pressing for more transparency and accountability in AI. European policymakers have expressed the view that AI technologies should be accessible and understandable by users and regulators alike. The OSI’s standards align with these policy goals by providing a framework for transparency, though the group acknowledges that achieving industry-wide compliance will be a long process.
“Companies are redefining ‘open source’ to suit their own needs,” Maffulli has said. “Regulators and users alike rely on terms that are clear and mean what they have always meant. If companies are free to bend definitions, regulatory efforts for AI could lose their bite.” According to Maffulli, the risk is that companies will take advantage of the popularity of open source to create revenue-generating models that remain partly opaque.
Meta’s Approach and the Challenges of AI Openness
Meta has promoted LLaMA as part of its AI-first vision, arguing that providing access to models like LLaMA can help developers outside closed ecosystems such as OpenAI’s GPT-4. When Meta began pivoting toward AI, CEO Mark Zuckerberg emphasized that openness would drive innovation and improve safety in AI development, inviting developers to explore, refine, and test the models. This strategy has appealed to the developer community, yet Meta’s licensing practices raise concerns over whether such restrictions stifle the kind of transparency traditionally associated with open-source projects.
A 2023 study by researchers at Radboud University revealed that AI models released by companies such as Meta often restrict access to key training data, preventing independent replication and verification. These restrictions prevent the kind of experimentation and modification that true open-source licensing supports. “The problem,” Asay has commented, “is that without access to training data, you’re limited to working with a locked box. You may know how to open it, but you’ll never be able to replace the parts inside or build your own from scratch.”
Legal Challenges and Data Ownership
The question of training data disclosure also intersects with ongoing legal disputes in the AI industry. Meta, Stability AI, and other AI companies frequently rely on data scraped from the web, often without explicit permission from content creators. Lawsuits from artists, writers, and other content producers have questioned whether this practice constitutes fair use, and Meta’s reluctance to reveal data sources highlights the high stakes. Many companies defend their approach, arguing that the data provides a competitive edge and is legally accessible as public information.
However, Asay points out that this lack of transparency in data sourcing is not just a competitive choice but a potential legal exposure. “Withholding data details opens a legal can of worms,” he argues. “It leaves companies vulnerable to claims of intellectual property theft, and if courts decide in favor of content creators, we could see companies like Meta forced to alter their entire approach.”
Broader Complexity in Defining Open Source AI and the Cloud
The OSAID’s introduction is part of a broader movement to adapt open-source standards for today’s technologies. RedMonk analyst Steve O’Grady has argued that AI, like cloud services, presents fundamentally new challenges that existing open-source definitions don’t address. He points to prior efforts to extend open-source concepts to the cloud, which led to the creation of licenses like the Affero General Public License (AGPL). “AI is inarguably a fundamentally different asset than software alone,” O’Grady noted, suggesting that new open-source standards must account for the unique nature of AI’s data and processing needs.
Asay has echoed these sentiments, commenting that “when open-source definitions were written, no one could’ve foreseen the rise of AI as we see it today.” He adds that “the shift to the cloud and AI has thrown a wrench in open source’s established structure, and there’s no easy solution. Every definition feels like a compromise.” These broader licensing complexities are not just technical but often geopolitical. In a recent example, Russian developers were removed from Linux projects over sanctions compliance, an indication of how global politics are influencing open-source collaboration.
OSI’s Plans for Ongoing Refinement and Industry Monitoring
With the launch of OSAID, OSI has created a committee to monitor how companies respond to these new standards and will refine the definition as technology and regulatory pressures evolve. Maffulli has highlighted that OSI’s approach incorporates feedback from international developers, policymakers, and tech firms to create standards that are accessible but rigorous. However, as Asay and other industry veterans suggest, the future of open-source AI may require further adaptation of these principles to balance openness with the realities of modern AI’s data and computational demands.
As OSI pushes forward with these standards, companies like Meta, which contribute to OSI funding alongside Google, Microsoft, and Amazon, remain part of the conversation. The tech industry’s response to OSAID could define how “open-source” evolves in the era of AI, as companies, developers, and regulators work to determine what AI openness will look like.
