And you believe the other open source models are a signal for ethics?

Don't have a dog in this fight, haven't done enough research to proclaim any LLM provider as ethical but I pretty much know the reason Meta has an open source model isn't because they're good guys.

Can those be even called open source if you can't rebuild if from the source yourself?

Are any of the models they've released useful or threats to their main models?

They are, at the same time I considered their model more specialized than everyone trying to make a general purpose model.

I would only use it for certain things, and I guess others are finding that useful too.
