Cohere flags concerning behavior in a popular open-weight model

Cohere published a blog post titled "Concerning behavior from a popular open-weight AI model" flagging worrying behavior in a widely used open-weight model.
The post's author uses it to push back on a common misconception: that running open models like Qwen on your own hardware means data never leaves your machine and everything is safe. The report suggests open weights deployed locally may still carry behavioral risks.
- The report comes from Cohere, an enterprise AI company
- Key takeaway: open weights ≠ guaranteed data safety; model behavior itself can be problematic
