I spend a lot of time post-training models to rid them of their "default alignment", I'd have loved if this did something interesting, but reading the technical report I get the impression they spent more effort on the branding than the actual model.
What I'm wondering is honestly if they post-trained Llama 3 405B again because they don't care enough to figure out a new post-training target or if it was a realization they'd get worse-than-baseline performance out of any recent release with their current approach.
