Jev introduces a new shape of LLM - System One, aka Decision Models

Last week TypeSafe AI unveiled Jev , their first example of a new category of model that they are calling "System One models" (I'm with Maggie Appleton, I think "decision models" is a better name for these). Jev is an interesting variant on the usual LLM format: it still accepts text inputs, but instead of text output it returns floating point numbers corresponding to categories, yes/no…

When Claude CLI asks for feedback, responding authorizes conversation capture

Just an FYI. I had a funny feeling that when I don't dismiss the often appearing prompt to provide feedback on claude CLI's performance, I'm giving it authorization to capture the conversation. So I went and looked, and sure enough, it's in their terms. I went and looked because that prompt would appear really often and at points in my conversation where the transcript was long and potentially…
