I have a feeling this is like llama.

Original llama models leaked from meta. Instead of fighting it they decided to publish them officially. Real boost to the OS/OW models movement, they have been leading it for a while after that.

It would be interesting to see that same thing with CC, but I doubt it'll ever happen.

Yes, I also doubt it'll ever happen considering how hard Anthropic went after Clawdbot to force its renaming.
