If you're concerned about humans anthropomorphizing AI models, you might want to steer well clear of Anthropic, as their entire positioning (starting with the product name and continuing with UX choices and model releases) is built to attract the kind of researchers who are prone to believe in sentient machines.
They are going in the "Claude is alive" direction already and that line of communication is likely going full throttle in the nearby future.
I suspect the next big marketing gimmick is this supposed leak about capybara. I suspect the leak is intentional and meant to influence their expected IPO.
I think the big reveal is going to be that frontier models are no better than the open source models that you could feasibly run on retail hardware however they have a highly complex harness behind the API where the magic is.
