Timeline (last 90 days)
Block's AI lab released a full-duplex speech-to-speech model named Dessa.
Buzz comes from Block (Jack Dorsey's company) and is essentially a self-hosted Slack, providing infrastructure for collaboration between agents and between people and agents; it is not itself an agent.
Block released DESA, a speech model that supports local operation, can listen and speak in real time and can interject and respond, reportedly trained from scratch using only human speech without relying on text training or pretrained models.
In AgentScope, Message is composed of Blocks: TextBlock corresponds to text and ImageBlock corresponds to images; the content field of Message is a list of Blocks, supporting multimodal messages.
Block recently launched a new voice model, which the company says sounds "uncannily like a real person."
Block has not yet announced the voice model's detailed parameters, open-source plans, or a specific release date.
Block has not disclosed whether the voice model comes with watermarking or detection mechanisms.
The voice model can run locally on a MacBook M4 Max without relying on cloud GPU clusters.
The Block team released Dessa, which it officially calls "the most realistic full-duplex speech model to date".
The Dessa model was trained entirely from scratch on human conversation data, without relying on web text, books, or code.

50%UnverifiedThe business of payments company Block (such as Square and Cash App) naturally generates structured transaction data, access logs and risk-control signals, providing high-quality context input for AI models.
50%UnverifiedThe replicability of AI security solutions like Block's is questionable, because Block has its own in-house security team and ample engineering resources, and whether small and medium-sized enterprises can deploy at the same cost remains unknown.
50%UnverifiedBlock's AI system only "proposes patches" rather than directly deploying them, and human engineers retain the final decision to review and merge.
