It's amusing. Meta's AI team is more open than "Open"AI ever was - they publish so many research papers for free, and the latest versions of Llama are very capable models that you can run on your own hardware (if it's powerful enough) for free as long as you don't use it in an app with more than 700 million monthly users.
That's because Facebook is selling your data and access to advertise to you. The better AI gets across the board, the more money they make. AI isn't the product, you are.
OpenAI makes money off selling AI to others. AI is the product, not you.
The fact facebook release more code, in this instance, isn't a good thing. It's a reminder how fucked we all are because they make so much off our personal data they can afford to give away literally BILLIONS of dollars in IP.
Facebook doesn't sell your data, nor does Google. That's a common misconception. They sell your attention. Advertisers can show ads to people based on some targeting criteria, but they never see any user data.
Selling your data would be stupid, because they make money with the fact that they have data about you nobody else has. Selling it would completely break their business model.
