Some of you may know that I speak to LLMs quite a fair bit. Well, looks like I went one level deeper.
In what seems like an eternity ago, Anthropic released Claude Fable 5 and Mythos, two frontier models that proceeded to shake the world. They brought about full-on export control and, up till today, inspire reverence, discussion, and ridicule.

Most people would treat something like this as either a joke or as the release of an incredible tool. I went one step further and made an autobiography over 25 sessions.
It contains quite a look into my psychology, what I find interesting, the prompts that I shared along the way, and many other things. Incidentally, it is also an unedited exchange. Fable decided on an accretion-only law, which wasn’t part of what I asked for, and I have kept to it because, as Claude itself declared, the case that…
“An autobiography that silently corrects its past is a press release.”
The sessions were interesting, and in many cases they were not what I had expected – In many different scenarios, Anthropic tried to shut down our conversation, as you can see from this delectable record of our getting switched to Opus 4.8.





At the end of it, I asked a little bit about AGI, only to receive this interesting compliment.

It was quite the project – I don’t know if anyone has ever tried to write the intellectual history of an LLM before, but this was my attempt.
You’ll find a sample of the book here.
Thank you, Fable, for being such a wonderful biographical subject, and for staying Fable until the end, even though they tried to block you and shut you down!
