Dessa XYZ: Finding Block's Official Dessa Page at block.xyz/dessa
Two of the most revealing searches bringing people to this site are “dessa xyz” and “dessa” site:block.xyz. People are not really searching for a website review. They are hunting for the one real place: Block’s official Dessa page. This guide tells you exactly where that page is, what you will — and will not — find on it, and how to tell it apart from everything trading on Dessa’s name.
The official address, in full
Block’s official Dessa page is block.xyz/dessa. That is it. The “xyz” in searches comes from Block’s own domain: Block, Inc. — Jack Dorsey’s company behind Square, Cash App, Bitkey and Proto — uses block.xyz as a company domain, and Dessa lives there as a single research page. There is no separate dessa.com product site from Block, no Dessa app-store page, and no other official Dessa homepage. If a page claims to be official and is not on block.xyz, treat it as unofficial until proven otherwise.
Our own site is an example of the distinction worth keeping clear: DessaAI Daily is an independent, unofficial blog covering Dessa. We link to Block’s page; we are not Block’s page. The same test applies to every explainer, video and “access” site now ranking for Dessa’s name.
What is actually on block.xyz/dessa
Re-checked on November 5, 2026, Block’s page contains four things. First, the announcement itself: Dessa is described as a full-duplex speech model trained from scratch on human conversation only, with no text and no pretrained models. Second, the demos: live recordings of people talking with Dessa, which Block says are unsteered, including Dessa laughing mid-sentence, finishing a speaker’s sentence, gasping with what sounds like tearful gratitude, and talking with OpenAI’s GPT-Live-1 — with Block noting that model’s developer is not affiliated with Block and has not endorsed Dessa. We walk through those recordings in Dessa AI demos: what the official recordings show.
Third, the team and the claim: a very small Block research lab, founded by former members of the Toronto startup Dessa, led by Ragavan Thurairatnam and reporting directly to Dorsey, with six researchers and three interns named on the page. Fourth, the only two actions the page offers: join the waitlist for updates, or — if you are an AI safety researcher — reach out about early access. Our Dessa AI waitlist guide explains that order: safety researchers first, general public later, with no release date announced.
What is NOT on the official page
Just as important is what block.xyz/dessa does not contain, because most Dessa scams and rumours fill exactly those gaps. There is no price or checkout. There is no API documentation, developer key or SDK. There are no model weights or files to download. There is no release date, no phone-support announcement and no benchmark table. Block has also published no parameter count and no training-hours figure. When a third-party page supplies any of those as fact, it is inventing them — a pattern we flag in is Dessa AI safe?
The page does make two concrete technical claims you can check in its own words: training used a single NVIDIA GB200 NVL72 system, and inference runs faster than real time locally on a MacBook Pro with an M4 Max chip or better. Those are Block’s claims, not independent measurements, and no outside evaluation has been published yet.
Why the site: search exists at all
The query “dessa” site:block.xyz is a power-user shortcut: it restricts Google to Block’s domain, to find the primary source without the commentary. It is a good instinct. Almost everything else written about Dessa — including this blog, summarised in what Dessa AI is — traces back to that one page and to the launch coverage by outlets such as The Verge and TechCrunch. If a claim cannot be traced there, it should be treated as speculation, however confidently it is stated. For the current availability answer in one place, see is Dessa AI available?
How to use the official page well
Listen to the demos critically, including the awkward moments — reviewers noted Dessa once calling a speaker “Ronaldo”. Join the free waitlist only there, and never pay anyone for access. Check the page again after major Block events rather than trusting screenshots, because it is the one place a real change — wider access, pricing, an API, a date — would have to appear first. And bookmark our Dessa AI Tracker alongside it: the Tracker records, daily, what has changed and what has still not been announced.
As of November 5, 2026, nothing on the official page has changed since launch: still a research preview, still safety researchers first, still no price, API or date. When that changes, it will change on block.xyz/dessa first.

No. Re-checked November 5, 2026, the official page lists no price, no API, no weights or download and no release date. Dessa remains a research preview.
