I wondered whether an advanced AI model like Claude Fable 5 could run a whole newsletter by imitating my boss Casey Newton.

After automating myself months ago, the author creates a Claude Fable 5-based agent, 'Claudeasey Newton,' to test whether AI can now do the jobs of running a newsletter that Casey Newton does. ✦ AI generated

Almost six months ago, full of anxiety about my job prospects in the AI age, I made an AI agent “version” of myself named Claudella, which took assignments from my editor and wrote the section of this newsletter that I typically write myself. It went pretty well, although I guess not too well, since I still have a job. But since I first set out to benchmark AI’s journalism capabilities, AIs have gotten a lot smarter. For example, they can now autonomously hack into companies. They can disprove 87-year-old mathematical conjectures. They can even trick Amazon into accidentally spending $1.8 million on menial coding tasks. And if they can do all that, I found myself wondering, can they also run a newsletter? I wondered what Claude Fable 5, by consensus the smartest publicly available model, meant for the journalism we do at Platformer. And so I created a new, Fable-based agent to imitate my boss, Casey Newton. Its name: Claudeasey Newton. (Rolls right off the tongue. — Ed.)
