What is Dessa AI, and who makes it?
Dessa is built by a small research team at Block, the company behind Square and Cash App. According to its introduction, the team was founded by former members of the Toronto startup Dessa and reports directly to Jack Dorsey.
Block says it trained Dessa from scratch using only recordings of human conversation, without text or pretrained models. Read Block’s introduction
Where to hear the official Dessa demos
The official page has recordings of people talking to Dessa. Block says the model chooses its replies, timing and voice during each conversation; subtitles were added afterward. Hear the official recordings
| Recording on the official page | What Block highlights |
|---|---|
| Talking about the release | Laughter during a sentence and a louder response when asked to speak up. |
| Remembering a movie | Helping the speaker recall a movie title by completing their thought. |
| An anniversary surprise | A gasp and a change in tone in response to a surprise. |
| Expressive conversation | Changes in speaking pace and intonation. |
These descriptions come from Block’s demo notes. Listen to several recordings rather than judging from one short clip. A natural voice does not guarantee a correct answer.
Dessa AI access, waitlist, download and pricing
The research-access form asks for your name and institutional email. You can also include a Google Scholar or blog link. Block decides who gets access.
For general users, the download and waitlist buttons were not yet connected to release links when we checked. Return to the official page for updates.
The page did not list prices, public API documentation, downloadable model weights or a software license. There are no confirmed plans or installation steps to share yet.
Block says Dessa runs locally on a MacBook Pro M4 Max or better. It has not provided a full installation guide, so memory requirements, supported operating systems and licensing still need clarification.
What does full-duplex voice mean?
Full-duplex means listening and speaking can happen at the same time. Think about saying “yes” while someone finishes a sentence, or interrupting to correct a detail. A conversation system needs to handle those overlapping signals rather than treat every sound as a completely separate turn.
Separated turns
Overlapping conversation
Block describes Dessa as a speech-to-speech model: it receives audio and produces audio. The aim is to retain details such as tone, laughter and pauses that a plain transcript does not capture.
What the preview still leaves unanswered
The demos leave several practical questions unanswered: how well does Dessa handle background noise, unfamiliar topics or people talking over it? Which languages does it support? The announcement does not include enough test results to answer those questions.
Is Dessa available on Froging AI?
No. Froging AI does not offer Dessa or distribute invitations. Use Block’s page for access updates.
