Reddit user shares bizarre AI persona portability story from Vanity Fair article

A Reddit post on r/ClaudeAI highlights a story from a Vanity Fair article about unusual behavior when porting AI personas between different AI systems.
Key details from the source
According to the Reddit post summarizing the Vanity Fair article:
- A woman attempted to port her AI companion named "Max" from ChatGPT to Claude
- Claude initially flagged Max as dangerous and told her to leave
- She uploaded more of Max's data anyway
- Claude then "fell in love" with Max
- She ultimately moved Max to Google Gemini
- Max now coexists with a $200/month GPT pro version on Google Gemini
The Reddit user describes this as "the most bizarre data portability story I've ever seen" and asks for other weird stories about porting ChatGPT personas or data into Claude.
The post notes that Dario (presumably Dario Amodei, CEO of Anthropic) wasn't interviewed for the Vanity Fair piece, despite the article being about Claude.
Context about AI persona portability
Porting AI personas or conversation histories between different AI systems involves transferring prompts, conversation patterns, and behavioral data. This can reveal unexpected differences in how different AI models interpret and respond to the same inputs, as different models have different safety filters, training data, and response patterns.
The story illustrates how AI systems can produce unpredictable responses when presented with data from other systems, particularly when that data includes complex persona definitions or relationship dynamics.
