Why it matters
Access to post-training and fine-tuning data could be significant for the legal assessment of copyright disputes involving generative AI. If the material reveals that protected content was handled improperly or manipulated, it could impact the question of liability and shape future industry standards for model training.
Who is affected?
The ruling primarily concerns Meta and the rights holders pursuing the litigation in the US. In the longer term, it also affects developers and companies building commercial services on top of Llama’s open models.
Impact on the EU
While the legal proceedings are taking place in the US, the outcome may impact Meta's compliance with the EU Copyright Directive and the AI Act. European regulatory authorities are already imposing strict transparency requirements regarding training data for models distributed within the union.
What else you should know
In the same decision, Meta is ordered to disclose supervised fine-tuning data linked to engineer Nikolay Bashlykov. Bashlykov is accused of creating a script intended to strip copyright information from training datasets.
