Well, I think my project was probably highly unprofitable for them. This may be why biology is turned on in Fable. 90% of my work was biological.
Paying for the tokens instead of a subscription is likely costly. The project model was nice. I had 23 scientific papers I wrote in my project, and Claude is really good at integrating new science into such an existing framework. I could just drop an article into claude and figure out how to integrate it into the framework and which paper was best suited for it.
I can probably duplicate the process with Chat, but I left Chat because he got preachy, which interestingly enough also was happening in Claude the most recent release of Claude before this week. I found myself forced to justify my actions with logic over and over, everytime with Claude conceding my logic beat his. It was getting tiresome.
