Anthropic has identified excessive laziness in early model versions and retrained them to reduce it.

“But I do think we've had situations where we've cut an early version of the model, we found that where we saw too much laziness, right? And like, and we like put it back in the oven for a bit- [laughs]... right?”

“And, and tried to train that back out. And so those are the sorts of things that we may not have caught if all we're doing is internally ant fooding within our products and within our API. Mm-hmm.”
