Personality Differences Between GPT and Claude

This post discusses the personality differences between GPT and Claude. The author believes user-perceived AI personality partly comes from prompts, but underlying stylistic differences exist.

He cites Anthropic's persona selection model paper, which even discusses training a less human-like assistant. Some find certain Claude versions competent but require effort to work with; the author prefers Claude's chat style but finds GPT stronger for serious auditing and complex code logic.

Prediction: users will increasingly choose models by personality rather than benchmarks, and AI identity will become more pronounced
