"I am working within the organisation to create AI which integrates with machines and man from a manufacturing stand points . Having Open source definitions in Manufacturing is of utmost important from the point of worker safety and protections as workers within our org takes decisions based on how AI functions. Open source AI help my team develope and explain model behaviour to end workers and this in turn , based on worker feedbacks our models improve. I want to sponsor and be a part of this initiative so that I can passionately advocate openess to AI algorithms and model behaviour to make manufacturing safer for workers."

"Bloomberg supports the Open Source Initiative’s initial efforts to begin establishing a clearer definition for open source AI. This timely initiative is crucial as we and others navigate the rapid evolution of artificial intelligence models and increasing pace of adoption of this technology across enterprises. As an open source-first company, we hope that a common framework and definition for open source AI systems, data, code, models and weights will help foster more collaboration, faster innovation, and increased transparency within the AI community. We look forward to working with the OSI and others in the community to shape the future of open source AI for the benefit of all."

"We proudly support the Open Source AI License as it sets much-needed standards for transparency and accountability in open-source AI. For too long, the term 'open source' in AI has been used loosely, often without the clarity and transparency that traditional open-source software provides. Even in disagreements, the license provides a common framework and starting point to support further discussions. By requiring transparency in source code, data, model weights, and training processes, this license ensures that open-source AI is truly open, reproducible, and community-driven."

"Dear decision‑makers and professionals, The Open Source Initiative has issued a clear definition of Open Source AI. This definition is essential because: * It **prevents openwashing** and ensures products truly meet openness principles. * It **aligns OSAI industry to the EU the AI Act**, easing compliance and protecting citizens. * It **promotes transparency, reproducibility, and accountability** for models, code, and data. * It **fosters competitive innovation and international collaboration**, lowering entry barriers. * It **boosts user trust and AI safety**. The “open” claims of major tech firms' models are often proprietary, training data is undisclosed, and development processes are closed. This façade of openness masks centralized control and tracking, limiting verification, accountability, privacy and collective improvement. I strongly support this definition because it guarantees that AI is genuinely open—not just a marketing label—and delivers tangible benefits across Europe and the world."

"As a strong advocate for Open Source Software, I firmly believe that the future of AI lies in transparency and accessibility. Kerala State has long been an ardent supporter of Open Source Software, and we are committed to advancing Open AI systems that allow for collective inspection, continuous improvement, and a more ethical approach to technology development. In Kerala, we aim to ensure that AI systems are transparent, inclusive, and designed to serve the public good. Unlike closed-source systems where algorithms are opaque and their behavior unknown, Open AI fosters collaboration, ensures accountability, and helps eliminate bias through a community-driven process. I fully endorse the Open Source AI Definition as a pivotal step in ensuring AI technologies remain open, transparent, and beneficial for all. It is essential that we embrace openness in AI to not only make technological advancements but to ensure they are aligned with public interests and ethical standards."

"This is a much-needed definition. The industry has been loosely using the term "open source" to refer to machine learning models that are somewhat available to the general public, even though the benefits associated with the "open source software" concept are often absent in these models; this can potentially lead to confusion, misuse, and legal trouble. Having a precise baseline to classify models according to the same principles as open source software ensures users and businesses can understand how to choose, use, and benefit from the technology without having to worry about the fine print."

"The Open Source and Free Software ecosystem is a dynamic community of diverse organizations and individuals constantly innovating and improving, and, as such, has wholeheartedly embraced the artificial intelligence (AI) movement with all its potential for good, imprecisions and ethical misgivings, just as it has done with all previous technological advances. Given the indefiniteness and abuse surrounding Ai, it was therefore necessary to reach a clear and concise agreement on the meaning of Open Source in the context of Ai. The community is very grateful to the Open Source Initiative for starting the discussion and helping create a consensus around this definition.
