Of course you are right, I'd put it less carefully: The quoted Linux line is deceptive marketing.
- If we start with the closed training set, that is closed and stolen, so call it Stolen Source.
- What is distributed is a bunch of float arrays. The Llama architecture is published, but not the training or inference code. Without code there is no open source. You can as well call a compiler book open source, because it tells you how to build a compiler.
Pure marketing, but predictably many people follow their corporate overlords and eagerly adopt the co-opted terms.
Reminder again that FB is not releasing this out of altruism, but because they have an existing profitable business model that does not depend on generated chats. They probably do use it internally for tracking and building profiles, but that is the same as using Linux internally, so they release the weights to destroy the competition.
Isn't price dumping an anti trust issue?
