What are Open Weights?
Summary
The article explains that open weights are an important step toward making AI more transparent, but they are not the same as open-source AI. Open-weight models allow developers to download and use a model's trained parameters, making it possible to run, customize, or fine-tune the model. However, they usually do not include the training code, datasets, or detailed information about how the model was created. Without these pieces, it is difficult to reproduce the model, inspect it for bias, or fully understand how it works.
The Open Source Initiative argues that true open-source AI should provide access to the entire development process, giving users the freedom to study, modify, improve, and share the system. While open weights are certainly better than completely closed, proprietary models, they still offer only partial transparency. The article concludes that truly trustworthy, accountable, and collaborative AI requires openness throughout the entire pipeline—not just access to the final model weights.
