This is all marketing, you don't have to believe everything a company is saying about themselves, and you shouldn't.
Although, I could see Anthropic making a model purposely dangerous so there are bad outcomes and they can use that to their advantage for regulatory moats, and or in general make people think its more "alive" than it is. For some reason many people associate dangerous actions taken by llms with intent.
No kidding. If my LLM issues commands to an agent to delete files I want to keep, that's not "intent" or the model somehow become evil - it's just a bad model that's not doing what I want.
But, for marketing purposes, it's quite effective to portray your model as having some cosmic struggle between good and evil in itself.
