Rocky Linux founder launches OpenWALDO to bring transparency to AI training data

Rocky Linux founder launches OpenWALDO to bring transparency to AI training data

3 Key Points

  1. What happened

    Gregory Kurtzer, founder of Rocky Linux and co-founder of CentOS, released OpenWALDO, an open-source project designed to make AI training data transparent and auditable. The project's public corpus currently indexes 124 billion reference tokens across 75.1 million documents, organized into 20 corpora and 1,051 shards, with 18 asserted license identifiers.

  2. Why it matters

    AI training data has remained largely opaque and proprietary, with the MIT-led Data Provenance Initiative finding license-omission rates above 70% and license-error rates greater than 50% across 1,800+ text datasets it audited. OpenWALDO proposes making training data behave like open-source dependencies—named, reviewable, versioned, and attributable—so developers can verify sources and avoid problems like recursive training on outputs from other AI systems (model collapse).

  3. What to watch

    OpenWALDO's success depends on sustained supply of high-quality, legally usable data; trusted review and governance processes; and whether AI developers will adopt its provenance records as a standard part of model-development workflows. Kurtzer's company CIQ will support the project commercially rather than control it.

Context & Analysis

The AI industry has long struggled with opacity around training data sources and licenses. The MIT-led Data Provenance Initiative's audit of over 1,800 text datasets revealed a systemic problem: license information was omitted in over 70% of cases and miscategorized in more than 50%. This matters because models trained on data with unclear or incorrect licensing create legal and ethical risks for organizations that deploy them, and because training on outputs from other AI systems without proper attribution can lead to model collapse—a degradation in model quality caused by recursive training on synthetic data.

Kurtzer's proposal frames OpenWALDO as the missing layer in the "open AI" movement. While open-weights models (those whose parameters are publicly available) and open-source AI code have become more common, the training data itself has remained largely proprietary and unauditable. OpenWALDO introduces an AI Bill of Materials (ABOM) that tracks data lineage, licensing, and sources through training and release—practices borrowed from software development. The project positions this as shared infrastructure that would allow organizations to spend resources on differentiation rather than repeatedly sourcing and validating basic training datasets from scratch. Kurtzer explicitly draws a parallel to Linux's success, arguing that inspectability, forkability, and community validation—not certification—drove adoption.

The real test will be adoption. OpenWALDO must attract sustained contributions of high-quality, legally usable data; establish governance processes that command trust; and demonstrate that provenance records provide practical value in model-development workflows. CIQ will provide commercial support but not control the project, a structure intended to preserve its community character.

FAQ
What exactly is OpenWALDO, and what does the name mean?
OpenWALDO stands for Open Weights, Artifacts, Licenses, Data and Origins. It is a community-governed open-source project designed to create a shared, auditable corpus of AI training data and code that tracks provenance and licensing information.
How much training data does OpenWALDO currently have?
OpenWALDO's public corpus currently indexes 124 billion reference tokens across 75.1 million documents, organized into 20 corpora and 1,051 shards, with 18 asserted license identifiers.
Will OpenWALDO build its own AI model?
No. OpenWALDO does not plan to build a foundation model. Instead, it aims to provide a common base layer—a licensed, provenance-tracked training corpus that model builders can use, extend with proprietary material, and carry into their own training runs.
