Summary from the TLDR newsletter

Jev is a new category of model called 'System One models' that accepts text inputs, but only returns floating point numbers corresponding to categories, yes/no questions, ratings, and associated confidence scores. It is fast and really cheap - output is free, and input is $0.042 per million tokens. The model was released just under a week ago, but the amount of activity around it has been extremely impressive.
