Reach blends public engagement (views, likes, comments, shares, stars) from the platforms where the story or its original source lives: YouTube, Hacker News, GitHub, Substack and similar. A video and the article written from its transcript share one score, taken from the video. Platforms with no data are left out rather than counted as zero, and the age of a story never lowers its score.
Cohere, an AI developer, published a post saying a popular open-weight model behaves in a concerning way. The reviewed sources don't say which model it is, what the behavior is, or how it was found. [1]
Anyone can download and run open-weight models, so problems in a popular one could spread widely. Readers can't judge how serious or how reproducible this is until the model, the behavior and the method are disclosed.
