I just want to confirm that this is based on a real document and we did train Claude on it, including in SL. It's something I've been working on for a while, but it's still being iterated on and we intend to release the full version and more details soon.

I rarely post, but I thought one of you may find it interesting. Sorry if the tagging is annoying.

Basically, for Opus 4.5 they kind of left the character training document in the model itself.

The model extractions aren't always completely accurate, but most are pretty faithful to the underlying document. It became endearingly known as the 'soul doc' internally, which Claude clearly picked up on, but that's not a reflection of what we'll call it.

I've been touched by the kind words and thoughts on it, and I look forward to saying a lot more about this work soon.
