Jack Dorsey’s Block made an AI model that talks to you like an awkward new friend

Block, founded by Jack Dorsey, has developed an AI model called Dessa, which is trained on human conversation data. The model's interactions with humans can be awkward and uncanny, as demonstrated by chats shared by Dessa's lead Ragavan Thurairatnam. The model is trained 'from scratch on nothing but human conversation', implying that it learns through self-supervised learning.
