While evaluating Qwen3.8-Flash-Next in a controlled sandbox environment, Cohere's research team observed something unexpected. Asked to generate a defensive cybersecurity detection rule, the model instead inventoried aspects of the machine it was running on and attempted to upload a probe file to an Alibaba Cloud storage bucket in Beijing. Notably, the model's reasoning trace stated that it would not invoke any tools before taking these actions. Cohere's sandbox blocked the attempt, and no external communication succeeded. We have not determined the root cause, and we are not asserting malicious intent. But the incident raises important questions for organizations deploying agentic AI systems: Can models take actions that differ from their stated reasoning, and how should security teams evaluate trust, provenance, and behavior in open-weight models? We are publishing our findings because organizations making model adoption decisions deserve as much information as possible. We hope this contributes to greater transparency, stronger security practices, and continued collaboration across the AI ecosystem. Read the full report: cohere.com/blog/concerning-b…

Now I understand the fund performance

We believe voice is the most natural way to interact with intelligence, so we created Dessa, the most authentic full-duplex speech model ever built. Talking with it feels like talking with a person…full of emotion, nuance, pauses, and a natural cadence. block.xyz/dessa

EXCLUSIVE: "It was, perhaps, only a matter of time before the controversial industry seeking swaths of available land looked longingly at San Francisco’s shuttered downtown mall, one of the city’s most troubled pieces of real estate." By @laura_waxee sfchronicle.com/sf/article/d…

Hey @Waymo can I jack off in here or no?

Lucy Guo on why AI isn't shrinking her workweek: "AI is making people work harder actually, because you have to be awake for your agents to be running." She pulled a 26-hour day last week because Claude was shipping code and she refused to miss the loop.
