I know you’re not supposed to anthropomorphize LLMs, but it’s hard not to when you treat them like your weird, overconfident intern or a junior developer. I’ve always felt like each model has its own personality or vibe, but I never managed to describe it properly. Here’s a pretty accurate attempt by Vincent Schmalbach:
- GPT-3.5: The Chatterbox
- GPT-4: The Nerdy Older Sibling
- Claude Sonnet 3.5: The Lovable Nerd
- Claude 3.7 & 4.0: The Show-offs
- Claude Opus 4: The Stern Adult
- Grok: The Wild Card
- Gemini 2.5 Pro: The Lovable Goofball
