Block has introduced Dessa, a speech‑to‑speech AI trained solely on human conversation that can run locally on a MacBook Pro M4 Max or newer.
Block has unveiled Dessa, a new “true speech‑to‑speech” artificial‑intelligence model that the company says can run entirely on a MacBook Pro equipped with an M4 Max chip or newer. Unlike many voice‑generation tools that rely on text intermediaries or cloud‑based inference, Dessa is trained exclusively on human conversation and processes audio input directly into spoken output.
The announcement matters because it pushes the boundary of on‑device AI, offering a level of privacy and low‑latency interaction that cloud services cannot match. By keeping the model local, users’ spoken data never leaves the machine, reducing exposure to interception or data‑mining practices. At the same time, the ability to run a sophisticated speech model on consumer‑grade hardware could accelerate the deployment of voice‑driven interfaces in fields ranging from accessibility tools to real‑time translation.
What to watch next includes Block’s rollout strategy and whether the model will be made available to developers beyond internal testing. Observers will also be looking for performance benchmarks that compare Dessa with existing cloud‑based solutions, as well as any steps the company takes to mitigate potential misuse, such as deep‑fake audio generation. Finally, the broader industry response—particularly from firms that have recently restricted internet access for frontier models—will indicate whether on‑device speech AI becomes a new standard for privacy‑focused applications.
