Dessa AI on Hugging Face and GitHub: Is There an Official Model Page or Repo?
If you build with voice models, your first instinct after a launch like Dessa's is predictable: go and find it. Search Hugging Face for a model page. Search GitHub for an official repository. Look for weights, a demo Space, sample code — anything you can actually run. Developers are doing exactly that: searches for Dessa on GitHub have been arriving on this site in new phrasings all week. So here is the short, honest answer first: as of November 10, 2026, Block has published no official Dessa model page on Hugging Face and no official Dessa repository on GitHub. There is nothing to download, clone or run.
What you will actually find when you search
Search the model hubs for "Dessa" today and you will find the usual launch-week mixture: unrelated projects that happen to share the name, fan-made placeholders, discussion threads, and occasionally uploads that borrow a famous model's name to attract clicks. None of them is Block's model. Block's only official home for Dessa is its own page at block.xyz/dessa, which hosts the announcement, the team list and the live demo recordings. Everything Dessa is — for now — lives behind that page and the waitlist described in our Dessa AI waitlist guide.
This is consistent with everything else Block has held back. As we covered in is Dessa's code open source?, Block has released no source code and announced no licence. And as our open weights explainer sets out, it has released no model weights either. A Hugging Face model page is, in practice, a weights distribution channel — so no weights means no model page. The absence is not an oversight; it is the same gated, research-preview posture applied to every channel at once.
Why the hubs matter, and why rivals are there
The contrast with Dessa's closest rival is instructive. Kyutai's Moshi, the other full-duplex speech-to-speech system in this space, was released with open weights, which is precisely why it has a real presence on the model hubs: researchers can download it, inspect it, fine-tune it and publish derivatives such as NVIDIA's PersonaPlex. That openness is a large part of why Moshi became the field's reference implementation. Dessa makes the opposite trade. Block, a payments company whose products move money, is putting a small group of AI safety researchers first and keeping every artifact — code, weights, API — unreleased until that testing has run its course.
Neither choice is irrational. Open weights accelerate outside scrutiny and adoption; a gated preview limits impersonation and scam misuse of a voice that sounds convincingly human. But it does mean the developer experience of Dessa today is reading and listening, not building. If you need a full-duplex model you can actually obtain this week, Moshi is the one that exists on the hubs.
The impostor problem: treat hub uploads as untrusted
There is a safety dimension to the empty search results, and it matters more than the inconvenience. A model file is executable trust: downloading an unknown "Dessa" upload from a hub or a code repository and running it locally means running a stranger's code and weights on your machine. Launch hype creates exactly the conditions in which malicious or junk uploads spread — a famous name, no official artifact, and thousands of people searching for one. Our Dessa download guide makes the same point for apps and files: anything offered as a Dessa download today is not from Block.
Three habits will keep you safe while the official channels stay empty. First, verify provenance from Block's own page outward — if Block releases weights or code, it will be announced at block.xyz/dessa, not discovered on a hub. Second, treat any repository using the Dessa name, Block branding or the team's names with suspicion unless Block links to it directly. Third, never enter payment details, API keys or credentials into a "Dessa" demo, Space or installer; the real waitlist is free and lives on Block's page only.
What would change, and what to watch
Three announcements would change this picture overnight: model weights (which would make a Hugging Face page meaningful), source code under a stated licence (which would make an official GitHub repository real), or an API (which would give developers a hosted route instead — see our API documentation, SDK and keys explainer for what exists on that front: nothing yet). Block has announced none of the three, given no timeline for any of them, and published no parameter count that a model card would normally carry.
So the honest status is simple. Dessa has a web page, a waitlist and a set of remarkable demo recordings. It does not have a Hugging Face page, a GitHub repository, a download or a model card — and until Block says otherwise from its own page, anything you find under its name on the hubs is unofficial. We track every change to that status on this site, and the day an official repo or model page appears, we will link it here.

Frequently asked questions
Is Dessa AI on Hugging Face?
No. Block has published no official Dessa model page on Hugging Face, because it has released no model weights. Anything uploaded under Dessa's name there is unofficial and should be treated as untrusted.
Is there an official Dessa AI GitHub repository?
No. Block has released no Dessa source code and announced no licence, so there is no official repository. Block's only official Dessa home is block.xyz/dessa.
Why is Moshi on the model hubs but Dessa is not?
Kyutai released Moshi with open weights, so it can be downloaded, inspected and fine-tuned. Block chose a gated research preview for Dessa, with safety researchers first and no weights, code or API released yet.
