Jack Dorsey’s Block Announces Dessa AI Model Trained Exclusively on Human Conversation
Jack Dorsey’s company Block has introduced a new artificial intelligence model named Dessa. According to Block, the model was trained from scratch entirely on human conversation data. To demonstrate the capabilities and nature of Dessa, the company shared examples of chats it has had with humans. These shared interactions showcase conversations that can occasionally feel a bit awkward and uncanny. Dessa lead Ragavan Thurairatnam shared examples of these human-AI exchanges to highlight how the model communicates just like an awkward new friend.

In-Depth Analysis
Training from Scratch on Human Conversation
Jack Dorsey’s Block introduced Dessa, an artificial intelligence model built through a unique training methodology. Unlike many models trained on diverse web text, code, and mixed datasets, Block stated that Dessa was trained from scratch on nothing but human conversation. This specific focus shapes how the model interacts, aiming to mirror natural human dialogue dynamics rather than traditional assistant-style responses.
Demonstrating Uncanny and Awkward Interactions
To showcase Dessa, Block released examples of chats the model conducted with humans. According to details shared by Dessa lead Ragavan Thurairatnam, these conversations can occasionally be a little awkward and uncanny. Rather than presenting a flawless, hyper-polished assistant persona, the shared transcripts reveal a conversational style that resembles an awkward new friend navigating social dialogue.
Industry Impact
The introduction of Block's Dessa highlights ongoing experimentation in how artificial intelligence models are trained and presented to the public. By focusing training data exclusively on human conversation and embracing idiosyncratic or awkward communication styles, Block's approach contrasts with mainstream assistants designed for maximum efficiency and polish, pointing toward more niche conversational experiences in the AI space.
