“The new definition requires Open Source models to provide enough information about their training data so that a ‘skilled person can recreate a substantially equivalent system using the same or similar data,’ which goes further than what many proprietary or ostensibly Open Source models do today,” said Ayah Bdeir, who leads AI strategy at Mozilla.
Garbage. What this says to me is that they're going to allow companies that create models that were trained on data that would be illegal for you and me to scrape and regurgigate, to keep the data to themselves as long as they "provide enough information" for someone else that lacks the resources or legal impunity that companies have to theoretically re-steal the data. Which, you know, means that the models won't be reproducible by any reasonable standard, and can't actually be called open source.
But the OSI is just a handful of companies in a trenchcoat, so I'm not surprised by what they would call "open".
