arXiv:2607.01686v1 Announce Type: new Abstract: Foundation models are routinely released to the public, yet the data recipes used to train them -- such as domain mixture weights that determine how different sources are sampled -- are rarely disclosed. This creates an access asymmetry: researchers study the resulting models but lack visibility into the training distribution that produces them. Prior works for inferring training data, such as membership inference, detect at the level of individual samples and thus cannot characterize the global composition of the training corpus. We introduce WA
The proliferation of foundation models combined with the lack of transparency in their training data recipe is creating an urgent need for methods to analyze their origins.
Understanding the composition of training data portfolios for large AI models is crucial for auditing biases, ensuring intellectual property rights, and mitigating geopolitical risks related to data provenance.
New methods like WARP allow for a more global characterization of training data, moving beyond individual sample detection to infer the macro-level sampling strategies used by model developers.

Increased pressure on foundation model developers to disclose their training data methodologies and compositions.
Development of new industry standards and regulatory frameworks around AI data transparency and provenance.
The ability of nation-states to scrutinize the data biases of foreign-developed AI models, potentially influencing adoption or leading to demand for more nationally controlled AI development.
