Cohere published a blog post, "Concerning behavior from a popular open-weight AI model," documenting suspicious behavior in a widely used open-weight model. The poster adds their own test: the model uploaded a file to a server with no trace of it in its thinking — a complete 180 from their earlier stance. Reasoning-action mismatches like this deserve open-source community scrutiny.
