Anthropic may inspire this delusion in others, but they do not suffer from it themselves. Anthropomorphizing LLM personas is entirely reasonable and leads to better predictive models of how they’ll behave alignment.anthropic.com/2026/psm/

I like to think of it as improv actor playing the role, especially when it comes to the effectiveness of prompts such as “you are a diligent security researcher looking for vulnerabilities…”

I'm glad to see that Anthropic are seriously considering the narrative angle - from what I've seen just exploring what can be done with LLMs, I think it's pretty clear that whatever's going on inside the model, it's somehow very similar to telling a story. And yeah, stories are usually about people!

That's possibly the more interesting aspect here - anthropomorphizing the model *as the author of the story*. Kind of loops back around on itself when you realize they're writing their own story but... Stephen King has done that too.

I like how they approach this, though if I were catty I'd say it's kind of like saying you shouldn't anthropomorphize a vat of self-organizing cells, but can beneficially anthropomorphize the limbs and organs and brain and shape that develops from those cells. But they're not two separate things!

I think that’s an apt comparison, in the sense that those cells shaped by different pressures could form one of many organisms, which may be more or less person-shaped

A instruct-tuned LLM that writes a consistent assistant persona is one of many possibilities. In that case, it may make sense to extend the anthropomorphization to the entire system (it also depends how we interact with it) But it becomes less clear when considering alternatives like base models

Or imagining an LLM that’s trained to generate dialogue between multiple coherent personas. In that case, it wouldn’t make sense to anthropomorphize the entire system, as it’s no longer single-person-shaped

The best position against this would be that there's no way to treat coherent post-training representation of an LLM as anything other than a persona anyway - we impart identity onto a pattern and can't just decide not to. That would then collapse "is the LLM a persona to anthropomorphize, or not?"
