Block unveils Dessa speech model, but access is waitlist-only

Block has unveiled Dessa, a full-duplex speech model trained on conversational data. However, access to Dessa is currently restricted to a waitlist, primarily for safety researchers. The company has not released the model's weights, API, benchmarks, or a research paper, meaning all claims about its capabilities are currently unverified. AI

IMPACT This new conversational speech model's capabilities are currently unverified due to restricted access and lack of public data, limiting immediate industry impact.

RANK_REASON The item describes a new model release but notes significant restrictions on access and lack of public data, positioning it as a specialized tool rather than a frontier release.
